 Abstract
Microstructure and tensile strength of the vacuum brazed stainless steel(STS304) and WC-8 %Co were investigated. For brazing, the BNi-2, 3(A.W.S standard) were used as filler metals. It was found that metallic compounds of W-Ni were observed at the between WC metrix and brazed layer. Among these filler metals, the BNi-2 showed excellent wettability, but tensile strength was lower than BNi-3. The fracture of the brazed specimens with BNi-2 was occurred at the between WC metrix and brazed layer. The fracture of the brazed specimens with BNi-3 was occurred at the between WC metrix and brazed layer, and between brazed layer and stainless steel.
