ASTM D2649: Corrosion of Solid Film Lubricants

ASTM D2649 Corrosion Characteristics of Solid Film Lubricants

Aluminum is lightweight, strong, durable and corrosion resistant, making it attractive for use in construction, transportation and many other applications. This test determines the corrosion resistance of aluminum panels coated with solid film lubricants. It is intended to predict problems that may occur when aluminum is subjected to high humidity environments.

Two aluminum panels are compared in this test. The first panel is treated and cured with the test solid film lubricant. The second is left untreated. The two panels are placed together in the test assembly, a load is applied, and the assembly is heated and placed in a constant humidity chamber for the test time. The assembly is removed, disassembled and visually examined. Any pitting, etching or formation of white deposits is reported.
