- W2358421127 abstract "To solve the wear resistance of wear parts involving vertical mill,squeeze roller,and wear resistant plate used in cement,power,and metallurgical and mining industries,the iron-based flux-cored wire for hardfacing was developed.The hardfacing alloys with carbon(4%-6%),chromium(20%-35%)and other alloy elements of no more than 10% were prepared with the method of overlaying welding by designing different proportion of graphite,chromium carbide-iron powder and some additive agents of flux-cored wire.The microstructure and hardness of hardfacing alloy were tested and analyzed.The percentage of area and size of carbides in hardfacing alloy were determined.The wear resistance of alloys was evaluated.The results show that the microstructures of hardfacing alloys consist of primary carbide(Cr,Fe)7C3,eutectic carbide(Cr,Fe)7C3,residual austenite and other trace amount of carbide.The more the amount of primary carbides is,the higher the hardness of hardfacing alloys is.The mass loss increases first,and then decreases.Proper additional elements such as Nb,and Mo can improve wear resistance of hardfacing alloy by forming solid solutions and producing fine and dispersed hard carbides.Six types of flux-cored wires are successfully developed by designing and expermenting." @default.
