Molybdenum-Based Coating for Aerospace Applications
Background
Chromate conversion coatings (CCC) are applied to the surface of aluminum alloys to prevent corrosion; however, chromate is a known carcinogen. The United States and Europe have even banned the currently used CCCs, but the ban has been suspended for aerospace and defense industries since no replacement has been found; thus, the development...
