Dry film Q&A's; Mil-PRF-46010
RFQ: I am in need of a dry lubricant that has very low VOCs and passes MIL-L-46010/MIL-PRF-46010 [from DLA] . We currently are using the Nordson electrostatic rotary atomizers (RA-20s) to spray the material. Therefore, we are unable to use a water-based material without doing a major overhaul to the system. Is there anyone out there that has found a compatible low VOC lubricant and uses it in such a system? I currently use an Acheson product and I am investigating EM coatings, Dicronite, and Tioga. Any others?

A. You could try using Boron Nitride formulations produced by Saint-Gobain advanced ceramics.

Q. What is MIL-L-46010/MIL-PRF-46010 [from DLA] dry film lube? I have a print in which that spec. is called out. I need to know a process or product.

A. Hello Mike!
The current version of that specification is MIL-PRF-46010
[from DLA]
F, and the 20 page document is available for free at
assist.daps.mil. But it really sounds like you want the Qualified Products List that the military sometimes publishes for their specs. Here, you're in luck- you can get QPL-46010
[on DLA], a one page document listing two products. That doesn't mean you can't use others- just that the ones listed are OK by the DoD folks, and you may have to prove to them that others are acceptable.
Good Luck!

Dry film lube in single aerosol cans
Q. Do any of you know a source for small quantities, such as aerosol cans, of moly or PTFE dry film lube?

A. Hi Jeffrey. Bicycle shops have spray cans of teflon, as this is the lubricant of choice for bicycle chains. Auto stores may have it. You can also order Molybdenum Spray [affil links], but qualifying to a particular MIL spec might be something else.

A. Any industrial supply house such as Grainger or MSC. A wide variety of manufacturers sell dry film lube in aerosol cans. Also check out LPSlabs.com for technical information on these products.

DOD-L-85645 cross references
Q. Since DOD-85645 dry lube has been deactivated, what is a MIL Spec equal?
I hear that MIL-PRF-46010 [from DLA] Rev. F is an equal, but I have nothing to confirm.
This is Tungsten Disulfide in a lamellar form.
Hardness- 1.0 - 1.5 Moh's scale
Molecular weight: 248.02
Thickness: 0.000020 inch (0.5 microns) max.
Temp. range: -350 °F to +1000 °F.
Thanks for any information you may be able to give me.

A. DOD-L-85645 is inactive for new designs as you point out. There is an analogous SAE specification AMS 2530 which links to DOD-L-85645 Type 1 and can be used going forward. We provide a coating that conforms to this, Dicronite dry lubrication.

Q. Per the MIL-PRF-46010 [from DLA] QPL, I'm spraying material 9002. We do not have the other two products listed. We are having some difficulty having it adhere to the parts. We have Stripped (abrasive blasted) the parts twice now. Should I order the other materials listed in the QPL? What material do you recommend?

A. MIL-PRF-46010
[from DLA]
is a qualifying specification, it qualifies the product out of the can. There is not an application specification for Dry Lube.
You didn't state what you are trying to get the Dry Lube to adhere to, I'm assuming you are applying it to steel. We phosphate before applying the Dry Lube and have no problems with adherence. If you can't phosphate prior to Dry Lube alkaline dip your parts to remove any organic residue that may be left on the surface.
Hope this helps.

Need a High Volume Immersion Dry Film Source PRF-40610
RFQ: I have an opportunity for high volume (500,000 pieces) anodized work that requires dry film per MIL-PRF-46010
[from DLA]
.
I do not have a source for the dry film as of yet. This must be an immersion process to be cost competitive.

Q. Dear Sir,
I want to coat dry wax film on silver plated stainless steel 316 nut. Please help me with the procedure of coating.

A. Hi, Abdullah. I am a little unclear about what kind of coating you wish to apply and why -- but I am thinking you are probably interested in a Dry Lube? The appendix of the referenced spec, Mil-PRF-46010, includes application instructions.

Suggested OVEN for baking parts after Dry Film Lubrication
Q. We are a small-mid size company in NJ.
Some of the parts that we manufacture require Dry lubrication coating per MIL-PRF-46010.
We need help in selecting the right oven to do this.
Job run would typically require an oven space 12" x 12" x 12".
Can you please help?
Thank you

A. Hi Charles. This is a dry graphite spray, and MIL-L-24131 [link on DLA] covers dry graphite sprays, but I'm wouldn't know if LU204 can or can't comply. Could you please try to explain your situation that motivates this question? Thanks.

Q. We are new to the process called Solid film lubricant as per MIL-PRF-46010H and when I read the standard I found a few queries in coming months and planning for an NADCAP audit. Please help me out.
Questions as mentioned below:
1) Tiolube 20/20 is the lubricant we are using on Stainless steel and steel., This is a water base SFL; my question is whether sandblasting is a must for the process on stainless steel and steel? And should I need to record viscosity using a viscosity meter?
2) MIL-PRF-46010
[from DLA]
calls for many tests and my customers ask for testing like thickness, load carrying capacity, salt spray, film adhesion, solids content. My question is should we do all the testing in periodic (monthly) as MIL-PRF-46010H does not show any line telling periodic tests.
3)MIL-PRF-46010 4.4.2.2 says 2 steel disks and six sets of pins and vee blocks and not understanding what is all that exactly meant, all those are readily available (or is there any dimension)?
