Influence Mechanism of Y2O3 on Stellite156 Co-based Alloy Coating Prepared by Laser Cladding AITranslate
Abstract AITranslate
In order to improve the toughness and hardenability of H13 die steel,as well as prolong its service life,Stellite156 Co-based alloy coating was prepared on its surface by laser cladding.During the cladding process,in order to reduce the pores,refine the grain size and improve the hardness and wear resistance of the coating,Stellite156 Co-based alloy coatings with different Y2O3 contents(0,0.5%,1.5%,2.5%,3.5%)were prepared.The morphology and porosity of the coatings were analyzed by metallographic microscope,the microstructure and phase composition of the coatings were analyzed by SEM and XRD,the segregation of alloy elements in the coatings was analyzed by EDS,the hardness of the coatings was tested by microhardness tester,and the wear resistance of the coatings was tested by friction and wear tester.The experimental results reveals that Y2O3 content has little effect on the appearance of the coating,and less Y2O3 content can improve the heat convection in the molten pool and effectively reduce the number of pores in the coating.When Y2O3 content is 2.5%,the pores in the coating increase,and the coating phases mainly include Cr-Ni-Fe,Cr,Ni17W3 and a small amount of Y2O3 and(Cr,Co,Ni)23C6.Compared with the coating without Y2O3,the grain size of the coating with 2.5% Y2O3 is significantly reduced,the grain arrangement is more compact and orderly,and the composition segregation in crystal grains and grain boun-daries of the coating is also significantly improved.When the Y2O3 content increases from 0 to 2.5%,the maximum average HV microhardness of the coatings reaches 560,which is higher than 500 of the substrate.However,when the Y2O3 content continues to increase to 3.5%,the hardness of the coating significantly decreases,even lower than that without Y2O3.Therefore,a proper amount of Y2O3 can improve the pore defects,refine the grains,improve the composition segregation,increase the hardness of the coating,and then improve the wear resistance of the coating.
