CORROSION OF SOLID FILM LUBRICANTS: ASTM D2649
EXPLANATION
This test method evaluates the corrosion characteristics of dry solid film lubricants under conditions of high humidity. Surfaces are examined for signs of corrosion, which is an indication of potential field failure.
TEST SUMMARY
An aluminum panel with a solid film deposited on one surface is contacted under load with the surface of an unlubricated panel. The specimen is subjected to 95 +/- 3 % relative humidity at 49° C (120° F) for a period of 500 h. At the end, the surface of the unlubricated panel is examined for the evidence of corrosion.
TEST PRECISION
This is a pass-fail test and normal precision or bias statements are not applicable.
