  • A laser cladding has been processed on the 30CrMnSiNi2A which is often used in mading plane landing gear by using three kinds of alloy powder,and the contact fatigue erosion test is done with the high-frequence queching sample,then the wearing resistance is compared by using the method of weight loss. The microhardness distribution,microstructure and properties of cladding and transition layer of nickel-based alloysample are analysed.The results show:the wearing resistance can be greater improved by laser cladding process,among these three kinds of alloy powder,the wearability of Ni+ 30% WC is the best.
