扩散处理对黄铜上电镀铝层结构与性能的影响牛洪军，宋国泰（吉林工业大学长春１３００２５）（吉林省电力试验研究所长春１３００２１）１前言与热浸镀铝和固体粉末渗铝相比，熔盐电镀铝具有操作温度低、工艺易控制、镀层表面质量好等优点．但是，熔盐电镀铝常常会形成粗大树枝晶，出现镀层疏松和显微裂纹ｔ‘－’］，使镀层的耐蚀性下降．本工作以黄铜为基体材料，采用ＡＩＣＩ。－ＮａＣＩ熔盐为镀浴，并通过低温扩散处理，?...
The structure, adherence and corrosion resistance of aluminium coating electro-plated on brass from amolten salt bath consisting of AlCl3-NaCl were studied. after heating in the temperature range of 300-380℃, the grains of the aluminium coating were refined, its compactness increased, Cu and Cu9Al4 phaseswere formed and corrosion resistance was improved.
