Research progress on high-temperature wear properties of metal materials containing wear-resistant phases
With the continuous development of aviation,military industry,nuclear industry and other fields,higher requirements have been put forward for the mechanical equipment and its components working in high-temperature environments.High temperature wear is the main cause of failure for mechanical parts,and wear-resistant phases play an important role in the high-temperature wear performance of metal materials.This article reviews the research progress on the high-temperature wear performance of metal materials containing wear-resistant phases such as oxides and carbides at home and abroad,and analyzes the role of wear-resistant phases in high-temperature wear.On the one hand,the wear-resistant phases improve the hardness and strength of the metal matrix by refining the grain size,thereby improving wear resistance.On the other hand,the oxide formed during high-temperature wear promotes the formation of a protective film,improving the material's oxidation resistance and high-temperature wear resistance.
