Abstract
TiN- and (Ti,Zr)N-coated (sic)-961 steel turbine blades were tested in a specially designed electrically heated test unit for gaseous abrasi ve-corrosive wear. The relative decrease in the wear resistance of the coatings with an increase in temperature is inversely proportional to the concurrent squared relative decrease in the internal macrostress of the coatings. (Ti,Zr)N coating proves to be more efficient for corr osion and erosion protection.
