Development and wear resistance enhancement of wear-resistant steel
Wear is one of the main causes of material failure.Wear-resistant steel is a kind of wear-resistant ma-terial widely used in various wear conditions.The continuous development of industrialization level puts for-ward higher requirements for the performance of wear-resistant steel,and both high strength and good tough-ness are important directions for the development of wear-resistant steel.Driven by demand,wear-resistant metal materials have experienced the iterative development of manganese steel,nickel hard cast iron,high chromium cast iron and low alloy steel,resulting in many types of wear-resistant steel.In this paper,accord-ing to the development history of wear-resistant steel,the characteristics,application scenarios,research sta-tus and shortcomings of various wear-resistant steel are introduced in turn on the basis of the classification of wear-resistant steel,and four methods of wear-resistant steel including alloying,rolling,heat treatment and surface engineering are summarized,and the future research direction and development prospect of high-per-formance wear-resistant steel are prospected.
