Abstract

En 中文

• Trace Ti addition inhibits NbC agglomeration, achieving uniform morphology control. • Ti-modified alloy exhibits superior friction/wear resistance from RT up to 600℃. • Protective oxide film thickens with temperature on the coating surface, dominating the enhanced wear resistance.
