Investigation on the Bonding Strength between the Hard Alloy Cladding Layer and the Steel Substrate

Abstract:

By virtue of the technology characteristics of liquid-phase sintering ternary boride hard alloy cladding material, two steel plates were bonded together by a ternary boride hard alloy cladding material through a liquid phase sintering procedure. The bonding strength between a hard alloy cladding layer and a steel substrate was characterized by means of measuring the bonding strength of two steel plates bonded by the hard alloy cladding layer. The bonding strength between hard alloy cladding layer and the steel substrate was measured by transverse rupture strength method, tensile fracture method and single side shear method, respectively. The results show that a firm metallurgical bonding is formed during the liquid phase sintering.
