摘　　要：在无铵助镀剂中添加不同浓度的表面活性剂,助镀后的工件经烘干处理,利用扫描电镜观察、测量盐膜厚度以及使用电子天平称重等方法,研究表面活性剂对助镀剂盐膜微观形貌、盐膜厚度和工件表面上单位面积盐膜质量(载膜量)的影响。结果表明:表面活性剂能有效改善助镀剂盐膜在工件表面的形貌和分布,有助于改善助镀后工件表面盐膜厚度均匀性,并且能够显著地减少工件表面上助镀剂盐膜的质量。Adding surfactant of different concentrations in ammonia-free fluxing agent and drying after fluxing, the effects of surfactant on the properties of ammonium-free fluxing fill in hot dip galvanizing were studied by SEM, thickness measuring and weighing method. The results show that the surfaetant can effectively improve the fluxing film morphology and distribution on the workpieee surface, can improve the uniformity of the fluxing film thickness and can significantly reduce the qualities of the fluxing film.
