SURFACE TREATMENT OF TITANIUM ALLOYS: A REVIEW OF PUBLISHED INFORMATION,

Abstract

This report reviews the use of lubricants and surface coatings to improve the wear and galling resistance of titanium alloys. The methods of coating discussed are anodic oxidation, plating, metal spraying, deposition from a vapour phase, diffusion treatments with gases and in active salt baths, metallic diffusion coatings, surface hardening by heat treatment, chemical conversion coatings and plastic coatings. It is concluded that the most important criteria for a coating for highly stressed components with heavy surface loads are: (1) wear and galling resistance must be good; (2) strong adhesion between coating and substrate must be achieved; (3) the coating must withstand high loads and sliding forces, and (4) mechanical properties of the underlying titanium alloy should not be impaired by the coating.
