High-efficiency hard alloy surfacing electrode and process flow thereof

The invention relates to a high-efficiency hard alloy surfacing electrode and a process flow thereof, in particular to a surfacing material for working such as oil drilling, well-repairing tool, fishing and windowing and the like. The high-efficiency hard alloy surfacing electrode is made of hard alloy particles and matrix alloy, wherein the matrix alloy comprises the following materials in partsby weight: 48-52 parts of copper, 28-32 parts of zinc, 13-15 parts of nickel, 3.5-4.5 parts of aluminium and 1.5-2.5 parts of manganese. The process flow comprises the following steps of: a, arranging a forming mold into a preheating box for preheating, and adding hard alloy particles; b, adding matrix metal in the obtained product, and moving into a high-temperature vacuum box; c, moving into a low-temperature box; and d, obtaining a finished product. The matrix metal is selected from alloy materials of copper, nickel, zinc, aluminium, manganese and the like and has the advantages of large tensile ...
