Research progress in preparation technology of high temperature wear resistant coating on H13 hot working die steel surface
In industry,H13 hot working die steel is widely used,but it experiences wear at high temper-atures,and fatigue failure is widespread,which greatly affects the safety of production,and seriously damages the economic effect.In order to better investigate and analyze the high temperature wear of H13 hot working die steel,domestic and foreign scholars apply the surface modification technology to improve its performance and its service time,this paper summarizes those research status,on the laser cladding,thermal spraying,va-por deposition,chemical heat treatment boronizing,carburizing,nitriding,and multi-element penetration technologies,analyzes the advantages and disadvantages of the modification of H13 hot working die steel ac-cording to its different methods,and prospects the development of preparation technology of high temperature wear coating for H13 steel.
