%X 摘要 采用LD30铝合金与304不锈钢低温钎焊工艺进行润湿性研究。通过润湿性研究对比,选用了60Sn-40Pb、Sn-3.5Ag和35Sn-40Pb-25Bi3种 适用于LD30铝合金和304不锈钢的低熔点钎料,并针对每种钎料选取与之相匹配的钎剂。分析了接头的微观组织、化合物相成分和X射线探伤。结果表明:60Sn-40Pb 和35Sn-40Pb-25Bi与H3PO4组合在304不锈钢上润湿性很好;不锈钢与镀镍层铝合金钎焊试验时,60Sn-40Pb和35Sn-40Pb-25Bi与50% H3PO4+50%乙二醇组合润湿性很好;Sn-3.5Ag 钎料润湿性相对较差。<br>Abstract：LD30 aluminum alloy with 304 stainless steel using low temperature brazing was performed in the wettability research. Through wettability study contrast, three kinds of low melting point solders 60Sn-40Pb, Sn-3.5Ag and 35Sn-40Pb-25Bi which were suitable for LD30 aluminum alloy and 304 stainless steel were chosen, and solder flux was selected. The joint of microstructure, phase composition, X-ray inspection were analyzed. Results show that the 60Sn-40Pb and 35Sn-40Pb-25Bi combine with H3PO4 have good wettability on 304 stainless steel; the 60Sn-40Pb and 35Sn-40Pb-25Bi combine with 50% H3PO4 and 50% glycol have good wettability in the brazing experiment and the Sn-3.5Ag has relatively poor wettability.
