Open publisher page 0 citations

Abstract

The Cu alloy coating on the surface of 45 steel was prepared using plasma spraying technology,then remelting treatment was carried out.The effects of remelting treatment on microstructure and properties of 45 steel coating were studied by metallographic microscope,XRD,and so on.The results show that the microstructure of the coating becomes more uniform and density with remelting treatment.The metallurgical bonding strength increases a lot,the hardness of coating and the matrix near combined improves greatly.
