Abstract
Electroplated chromium coatings on automobile suspension damper piston rods are replaced with thermal or kinetic spray coatings of: (a) suitable corrosion-resistant metal alloys such as iron and chromium containing nickel-based alloys or chromium containing steels, or (b) suitable ceramic coatings such as electrically insulative alumina ceramics. The spray coatings are porous, and the metal alloy coatings usually should be sealed for corrosion protection.
