Description
The behavior of several different types of plasma-sprayed coatings applied to typical α + β titanium alloys was studied in air at elevated temperatures. Ductile coatings of MCr and MCrAlY type were found to confer protection against oxidation and embrittlement for hundreds of hours during rapid thermal cycling in flowing air to at least 850degC. Measurements of the extent of interdiffusion of elements across the coating-alloy interface as functions of time and temperature were made. Typically, cobalt and iron from a coating may penetrate to depths of a few tens of micrometers into the alloy substrate after 1000 h exposure at 850degC. (orig.)
