New Protective Coatings for Replacing Cadmium Coatings on Steel Parts

  • Published:
Metal Science and Heat Treatment Aims and scope

Abstract

Works aimed at solving the problem of replacing toxic cadmium coatings used for protection of aircraft steel parts are reviewed. Numerous electrolytic alloys based on zinc and zinc-bearing coatings of the “Colsil” and “Dacromet” types are suggested for the purpose. A VIAM-designed coating based on a Zn – Sn alloy in combination with a modified phosphate coating is considered. It is shown that the protective properties of the combined coating are close to those of a cadmium coating, and the former is recommended for commercial use.
