The scheme of gas-abrasive wear test of turbine compressor blades under free vibration of blades, including at high temperatures, is proposed. The amplitude-and time-dependences of the wear rate of ∋Ee Cyrillic sign961-steel and BT8-alloy blades, having either with or without a (Ti,Zr)N coating, were compared. The coating's effectiveness is almost the same for both cases at 20°C, but at 150°C, it is lower for steel blades because of spalling the coating due to its deficient adhesion.
