激光熔覆在新型耐磨板ZM4-13上的应用
Application of laser cladding on the new wear-resistant plate ZM4-13
摘要
Abstract
To further enhance the service life of the chute,iron-based self-fluxing alloy powder was chosen,and laser cladding was employed to conduct surface strengthening on the new wear-resistant plate ZM4-13.The microstructure,microhardness,wear resistance,and impact resistance were analyzed using optical microscopes,scanning electron microscopes,energy dispersive spectrometers,Vickers hardness testers,wet rubber wheel testing machines,and impact testing machines.The results indicate that the wear-resistant layer is mainly composed of Cr-rich dendrites and eutectic structures between dendrites.After the strengthening by laser cladding,the performance of the wear-resistant plate has been significantly improved compared to the ZM4-13 substrate.Specifically,the microhardness of the cladding layer is 251.9HV5 higher than that of the substrate,the wear resistance of the cladding layer is 3.02 times that of the substrate,and the longitudinal and lateral impact resistance has increased by 26.0J and 20.4J,respectively.This research provides laboratory data references for the industrial application of laser cladding surface strengthening of the ZM4-13 middle plate.关键词
