CuZn钎料钎焊白口铸铁润湿性及力学性能

The Wettability and Mechanics Property of the CuZn Filler Metals Brazing White Cast Iron

研究了ＣｕＺｎ 系钎料钎焊白口铸铁润湿性及力学性能。结果表明， 含Ｚｎ３８％ ＣｕＺｎ 钎料润湿性和剪切强度最高。ＣｕＺｎ 系钎料在白口铸铁表面的润湿性和钎缝剪切强度低于在 ３５＃ 钢表面的润湿性和钎缝剪切强度。白口铸铁向钎料过度溶解所造成的溶蚀， 是钎料润湿性差和接头强度低的主要原因。

The wettability and mechanics property of the CuZn filler metals brazing white cast iron was investigated in this paper It′s shown that the wettability and the shear strength of the CuZn filler metals containing 38% Zn are the best The wettability and the shear strength for the CuZn filler metals brazing white cast iron are lower than these of the CuZn filler metals brazing 35 # steel The erosion of the white cast iron over dissoluing into the filler metals is the main reason reducing the wettability and shear strength
