Corrosion preventive compounds (CPCs) were evaluated using substrates comprised of five commonly used rotary wing aviation materials. The materials used were magnesium alloy AZ31B-H24 aluminum alloy 2024-T3, 4130 low alloy steel. 4340 high strength steel, and AM-355 stainless steel. The relative performance of each CPC was assessed in combination with the materials under several different tests. These tests consisted of general corrosion resistance. resistance to crevice corrosion attack. stress corrosion ...
