摘　　要：研究了6061铝合金钎焊用中温钎料Al-Si-Cu-Ni钎料的熔化特性、钎焊强度、钎料和接头抗腐蚀性能。结果表明,Al-Si-Cu-Ni钎料熔化温度与Al-Si-Cu钎料HL401接近,钎焊强度、钎料和接头抗腐蚀性能均优于HL401;Al-10Cu-10Si-2Ni钎料熔化温度低,抗拉强度和接头抗腐蚀性能高,适用于6061铝合金的钎焊。Melting characteristics,brazing strength,corrosion resistance of filler metals and joints of the Al-Si-Cu-Ni brazing filler metals for 6061 alloy brazing were studied.The results show that,the melting temperature of Al-Si-Cu-Ni brazing filler metals are close to the Al-Si-Cu solder HL401and the brazing strength,the corrosion resistance of filler metals and joints are better than HL401;Al-10Cu-10Si-2Ni filler matel with low melting temperature,high brazing strength and better corrosion resistance of joint is suitable for 6061 aluminum alloy brazing.
