【摘要】 本文研究了4J33、纯 Ni 和40Cr 钢与 ZrO₂的钎焊连接,结果表明:对 Ag₆₆Cu₃₀Ti₄活性钎料,4J33与 ZrO₂在1183K 时能形成连接,而在1103K 和1133K 时连接失败;纯 Ni 与 ZrO₂在温度升至1273K 仍不能形成连接,这是因为纯 Ni 和4J33所含的 Fe、Ni、Co 元素扩散到钎料中并与之发生反应形成化合物所致。40Cr 钢和 ZrO₂的连接钎料中未形成化合物,它们在1133K 就能形成连接。更多还原

【Abstract】 In this paper,the brazing joining of 4J33、pure Ni and steel 40Cr with ZrO₂ was studied.The results indicate:as brazing alloy Ag₆₆Cu₃₀Ti₄ is concerned,4J33 can be bonded with ZrO₂ at 1183K while can’t be done at 1103K and 1133K,The attempt to join pure Ni and ZrO₂ failed even at 1273K.Because the pure Ni and Fe.Ni、Co which 4J33 contains diffuse into brazing alloy and react with it,the joints are failing,There is no reaction product in the brazing alloy be- tween steel 40Cr and ZrO₂,Thus steel 40Cr and ZrO₂ can be bonded at 1133K.更多还原
