Plasma-powder surfacing of composite alloys based on cast tungsten carbides
A.I. Som
Plasma-master, Ltd., Kiev, UkraineAbstract
Wear resistance of deposited metal, depending on the quantity and shape of the reinforcing tungsten carbide particles, methods for their addition to the weld pool and type of matrix has been investigated. It is shown that the best combination of service and technological properties of the deposited metal is achieved at its carbide content of about 50 vol.%.
Keywords: plasma surfacing, filler powder, spherical tungsten carbide, matrix, wear resistance, carbide distribution, hardness, surfacing equipment
