| 摘 要： | 针对电弧钎焊连接镀锌钢板时的锌层破坏行为进行了系统的研究,使用氩气作为保护气体,分别对当电流为直流和交流,燃弧时间从1s至5s时的镀锌钢板表面宏观形貌和微观形貌进行了分析。结果表明当采用直流电弧加热镀锌钢板时表面Zn层除蒸发外,还有熔化并形成FeZn合金表层熔膜,但基体Q235钢没发生熔化。但因交流电弧"阴极锌层气化-剥离作用"使表面锌层严重破坏,并影响钎料的润湿铺展,因此交流电弧不能连接镀锌钢板。

| Abstract: | The destruction behavior of the galvanized layer during the argon arc brazing process is studied systematically.The arc brazing experiments are conducted by using the alternating arcing current and the direct arcing current separately from 40A to 80A.Results show that during the galvanized layer is melted and vaporized,the FeZn compound layer is formed on the base metal surface.However,the steel matrix will not be melted when the direct arcing current is used.On the other hand,the galvanized layer is heavil... |
