DOD-L-85645 A updated to AMS 2530 A
“Military Specification, Lubricant, Dry Thin film, Molecular Bonded”
How We Apply DOD-L-85645
AMS 2530 is the most recent mill spec for Tungsten Disulfide but if a drawing was made before 2007 the tungsten disulfide specification will be DOD-L-85645. There are many modified tungsten disulfide blends going under different brand names that reference DOD-L-85645 A, but the specification was written for tungsten disulfide (WS2) and tungsten disulfide is what we do.
DOD-L-85645 A vs. AMS 2530 A
The biggest difference between DOD-L-85645 A and AMS 2530 A is that AMS 2530 defines and clarifies the procedure of DOD-L-85645 A. DOD-L-85645 does not state a processing method it only gives suggestions in the appendix. However to pass the tests stated in DOD-L-85645 A an impingement method is necessary.
Still 100% Impinged
We process with Tungsten Disulfide (WS2). The Mil Spec DOD-L-85645 A alludes to impingement but doesn’t specifically state an application method.
