摘要(Abstract)：

采用溶剂法在430~530℃分别在Q235钢基体上制备了热镀Galfan合金镀层,运用扫描电镜、X射线衍射仪分析了浸镀温度对合金镀层界面组织的影响。结果表明:浸镀温度为430~450℃时,界面层生长速度缓慢;当温度高于470℃时,界面层生长速度变快,高温时界面层的生长速度为低温界面层生长速度的2倍。浸镀温度为430~450℃时,界面层分为两层,远离基体部分为圆片状组织,尺寸为1~3μm;靠近基体部分为椭球状组织,尺寸约为几百纳米。浸镀温度为470~530℃时,界面层全部为椭球状组织,尺寸为3~6μm。其中圆片状组织为FeAl_3相,椭球状组织为Fe_2Al_5Zn_(0.4)组成。随着浸镀温度的提高,界面层组织晶粒逐渐变大。
