Abstract

The effect of the intermetallic compound layer formed by atmospheric controlled induction heating fine particle peening (AIH-FPP) treatment on the wear resistance and high-temperature oxidation resistance of titanium alloy was investigated. To form an intermetallic compound layer on a titanium alloy by AIH-FPP treatment, pure titanium, aluminum and nickel particles were mechanically milled using a planetary ball mill, and the prepared particles were used as shot particles in the AIH-FPP treatment. The results showed that intermetallic compound layers, consisted of Ti3Al and Ti2NiAl3, were formed on titanium alloy by AIH-FPP treatment using the prepared particles. The wear resistance and high-temperature oxidation resistance of the AIH-FPP treated specimen were higher than those of the untreated ones.
