摘要
通过电化学Tafel曲线的测试,在室温3.5%氯化钠溶液中,对铜铝异种金属钎焊接头的电化学腐蚀性能进行了研究。结果表明:在钎焊过程中,施加一定压力,在一定的保温温度下,延长保温时间,可以提高接头的耐腐蚀性能。
The electrochemical corrosion properties of welded joints of Dissimilar Metal Connections of Copper and Alloy were studied hy measuring Tafel polarization curves. The results shows that the corrosion resistance of welded joint is better if imposed appropriate pressure and if made it in the longer holding time under the certain temperature.
