4.6.2 Film thickness and appearance. The bonded solid film lubricant specimens
shall be examined visually and microscopically at a magnification of 12X for uniformity
in color, smoothness and evidence of cracks, scratches, pinholes, blisters, bubbles,
runs, sags, foreign matter, grit, rough particles, and separation of ingredients.

4.6.3 Solids content. Stir the lubricant thoroughly, weigh 5.0 ± 0.5 grams into a
disposable weighing dish (Fisher Scientific catalog number 08-732). Place the dish
and contents into a forced draft oven maintained at a temperature of 49 ± 3°C for
18 ± 1 hour. Remove from oven and place in desiccator. Raise temperature of oven to
204 ± 3 °C and replace dish with residue into 204 °C oven for 1 additional hour.
Remove dish and contents and cool in a desiccator. When cool, weigh dish and
contents. Calculate percent by weight of solids in fluid lubricant as follows:

Percent total solids = Weight of solid materials (grams) X 100

Weight of sample (grams)

4.6.4 Storage stability. Set aside a one-quart qualification sample in a storage area
maintained at 25 ± 3°C for a period of 1 year ± 7 days. At the end of the storage
period, determine the endurance life (see 3.4.4), of the cured lubricant film, the
sulfurous acid - salt spray (see 3.4.7) for types I & III, and the salt-spray (fog) test
(see 3.4.8) for types II & III.

6. NOTES

(This section contains information of a general or explanatory nature that may be

helpful, but is not mandatory.)

6.1 Intended use. The solid film lubricant covered by this specification is intended
for use on aluminum, aluminum alloys, copper and copper alloys, steel and stainless

13
 MIL-L-0046010D

steel, titanium, and chromium and nickel bearing surfaces (see appendix for application
instructions). It is useful under the following conditions:

a. To touch up worn surfaces originally coated with lubricant conforming to

MIL-L-8937 or MIL-L-46010.
b. For sliding motion applications such as plain and spherical bearings, flap
tracks, hinges, threads, and cam surfaces.
c. Where conventional lubricants are difficult to apply or retain, or where other
lubricants may be easily contaminated with dirt and dust.
d. For use within 12 months from the date of manufacture.
e. Where temperatures may range from -68 °C to 204°C, intermittent exposure
to 260°C are acceptable.
f. If mechanisms are operated at infrequent intervals or are lubricated for life.
g. Where long-term corrosion protection is required under static conditions.
h. Where a solvent-resistant coating is required.
i. Where a lubricant requires extremely heavy load ability in initial start-up of
heavy loaded mechanism designed for fluid lubrication.

6.1.1 Use limitations. This lubricant should not be used under the following
conditions:

a. On materials which will be adversely affected by the curing temperatures of

204 ± 15°C for l hour.
b. In operations consisting of rotary motion above 100 rpm under heavy loads
where the possibility of conventional fluid lubricant contamination exists. The
cured lubricant film is highly resistant to conventional fluid lubricants, but the
high fluid pressures developed in heavily loaded sleeve type bearings
drastically reduces the wear life provided by the solid lubricant film.
c. On bearings containing rolling elements.
d. Where there is potential contact with liquid oxygen.

6.1.2 Corrosion protection life. This lubricant, when under static conditions, can be
expected to provide corrosion protection for five years in indoor storage and
approximately two years protection in outdoor storage when lubricant is applied over
phosphated steel to a thickness of 0.013 mm. Where maximum corrosion protection on
steel is desired, the lubricant should be applied over phosphated steel to a thickness of
0.025 mm. The heavier coating can be expected to provide outdoor corrosion
protection for approximately four years.

6.2 Acquisition requirements. Acquisition documents should specify the following:

a. Title, number, and date of this specification.

b. Issue of DoDISS to be cited in the solicitation, and if required, the specific
issue of individual documents referenced (see 2.1.1 and 2.2).
c. Type and color required (see 1.2).

14
 MIL-L-0046010D

d. Packaging, packing, and marking data with requirements in detail (see 5.1).
e. Quantity (see 6.2.1.1).
f. Specify application and surface preparation requirements.
g. Hazardous material identification and material safety data.

6.2.1 Age limitation. The lubricant should not be ordered for use beyond
12 months from the date of manufacture.

6.2.2 Packaging options. In the preparation of contracts or orders, it must be noted

that various options, choices and alternatives, as indicated in MIL-STD-290, may be
exercised in the preparation of this lubricant for delivery.

6.3 Qualifications. With respect to products requiring qualification, awards will be

made only for products which are, at the time set for opening of bids, qualified for
inclusion in qualified products list (QPL-46010D) whether or not such products have
actually been so listed by that date. The attention of the contractors is called to these
requirements, and manufacturers are urged to arrange to have the products that they
propose to offer to the Government tested for qualification in order that they may be
eligible to be awarded contracts or purchase orders for the products covered by this
specification. The activity responsible for the qualified products list is: Director,
US Army TACOM Mobility Technology Center - Belvoir, ATTN: AMSTA-RBF,
10115 Gridley Rd., Ste 128, Fort Belvoir, VA 22060-5843. Products will not be
considered for inclusion in QPL-46010D until such time as appropriate departmental
medical activity has reviewed all pertinent material safety data sheets (FED-STD-313).

6.4 Falex lubricant tester. Information pertaining to the Falex lubricant tester
(see 3.4.4) can be obtained from the Falex Corp., 2055 Comprehensive Dr., Aurora,
IL 60505. The attention of the operator is called to the fact that repeatable and
reproducible test results can only be obtained if the test instrument is in proper
calibration.

6.5 Material Safety Data Sheets. The contracting officer should identify those
activities requiring copies of completed Material Safety Data Sheets.

6.6 Application to end item. The lubricant shall be applied to end items in
accordance with the appendix of this document (unless otherwise specified in the
contract or purchase order) over surfaces that have been pre-treated as per the
appendix (unless otherwise specified in the contract or purchase order).

6.7 End Item Testing. When possible, it is recommended that film thickness and
adhesion be tested when lubricant has been applied to an end item. Testing with
laboratory coupons and test panels may not fully support lubricant performance when
applied to actual end item.

15
 MIL-L-0046010D

6.8 Disposal. Place in non-leaking containers and dispose of containers in

accordance with latest EPA, state and local regulations.

6.9 Classification changes. MIL-L-46010D provides a limited availability for type I

and type II lubricants. These products will no longer be acceptable for use in military
applications after two years beyond the publication date of this document. A type III
lubricant has been added which meets VOC content restrictions of a maximum 250g/L.
Type III can be cured at either 150 ± 15°C for 2 hours or 204 ± 15°C for 1 hour. When
cured at either temperature, type III will meet all performance requirements in this
specification (performance requirements will often be exceeded by the lubricant when
cured at the higher temperature).

30. REQUIREMENTS

30.1 General application instructions for all metals. Do not touch the pretreated
surfaces with the fingers. Stir the lubricant until thoroughly mixed, using a low shear
mixing blade. A mechanical paint shaker may be used for types I and II, but is not
recommended for type III as excessive foaming with waterborne products may occur.
Minor viscosity adjustments to type III may be made by adding deionized water
(1 megohm/cm or greater). DO NOT USE ORDINARY TAP WATER. Apply the
lubricant by brushing, dipping, or spraying to a nominal film thickness of 0.01 with no
reading less than 0.005 mm or greater than 0.018 mm and permit the coated parts to
air dry for at least 30 minutes (or flash cure at 65 to 70°C for 10 to 30 minutes) to
assure complete removal of solvent. Bake at 204 ± 15°C for one hour (type II and III)
or 150 ± 15°C for 1 hour (type I) or 2 hours (type III). The coated surface of the piece
must remain at the cure temperature for the specified time. This may require that the
coated piece remain in the oven for a period longer than that specified to assure
compliance with this requirement. The use of a thermocouple attached to the coated
surface to indicate the temperature of the coating has been found to be satisfactory for
determining the beginning of the timed baking period. In addition, the application of the
coating to parts shall be as specified in 30.2 through 30.7 unless otherwise specified in
the contract or purchase order.

30.2 Application on aluminum and aluminum alloys. Preclean the surfaces to be

coated with Aliphatic Naphtha conforming to TT-N-95 or any environmentally safe
cleaner that sufficiently cleans surfaces to pass ASTM F 22, but does not harm the
surface (i.e. hydrogen embrittlement, etc). Anodize and seal the surface in accordance
with MIL-A-8625, types I, II, or III, class l.

30.3 Application on copper and copper alloys. Preclean the surfaces to be coated
with Aliphatic Naphtha conforming to TT-N-95 or any environmentally safe cleaner that
sufficiently cleans surfaces to pass ASTM F 22, but does not harm the surface
(i.e. hydrogen embrittlement, etc). Sandblast the surfaces with 180-220 grit clean, dry
sand. Form a black oxide finish on the surfaces in accordance with MIL-F-495.

30.4 Application on magnesium and magnesium alloys. Preclean the surfaces to

be coated with Aliphatic Naphtha conforming to TT-N-95 or any environmentally safe
cleaner that sufficiently cleans surfaces to pass ASTM F 22, but does not harm the
surface (i.e. hydrogen embrittlement, etc). Anodize the surface in accordance with
MIL-M-45202, type I, class A, B, or C.

30.5 Application on steel. Preclean the surfaces to be coated with aliphatic

Naphtha conforming to TT-N-95 or any environmentally safe cleaner that sufficiently
cleans surfaces to pass ASTM F 22, but does not harm the surface (i.e. hydrogen
embrittlement, etc). Sandblast the surfaces with 180-220 grit aluminum oxide.
Phosphate in accordance with DOD-P-16232 (weight should be 11 - 22 g/m2), type M,
class 3 or type Z, class 3.

 MIL-L-0046010D
APPENDIX

30.6 Application on stainless steels. Preclean the surfaces to be coated with

aliphatic Naphtha conforming to TT-N-95 or any environmentally safe cleaner that
sufficiently cleans surfaces to pass ASTM F 22, but does not harm the surface
(i.e. hydrogen embrittlement, etc). Sandblast the surfaces with 120 grit aluminum
oxide. Passivate the surfaces with QQ-P-35, types II, VI, or VII as applicable.

30.7 Application on titanium and titanium alloys. Degrease the surfaces to be

coated with aliphatic naphtha meeting the requirements of TT-N-95 or any
environmentally safe cleaner that sufficiently cleans surfaces to pass ASTM F 22, but
does not harm the surface (i.e. hydrogen embrittlement, etc). Sandblast the surface
with 180-220 grit aluminum oxide and alkaline anodize.

30.8 Engineering tolerances. The operating thickness of this lubricant averages

from 0.008 to 0.013 mm per lubricated surface. This thickness seldom requires
alteration of established clearances between moving parts. There is one exception.
The lubricant coating thickness must be considered in the case of small parts which
normally operate with very little clearance. The cured lubricant film is relatively soft
and any interference produced by the thickness of the lubricant will cause rapid wear of
the lubricant film to the point where interference is eliminated.
