PLTL-23 Steel and Copper Corrosion per SAE-AMS-M-7866
Molybdenum disulfide has excellent lubricity properties and is therefore commonly used as a powder lubricant or incorporated into lubricating greases or oils. This test is intended to ensure that there are no corrosive components that could damage components in systems employing the MoS2 powder.
A steel panel and a copper panel are coated with a slurry of the sample and mineral spirits, heated, and examined microscopically for pitting, etching or stains. A “pass” is reported if no corrosion is observed.
