The results show that the addition of accelerators to the treating bath will accelerate the coating formation, and the added ammonium salt and chloride will change the Ce content in the coating from 5.93% to 4.15% and 9.27%, respectively. The added accelerators of ammonium salt and chloride could also increase the coating anti-corrosion performance to 2.6 times and 6.6 times against that treated without accelerator, respectively, and increases the micro-hardness of the Al surface from HV68.8 to HV389 and HV450, respectively.

结果表明：处理液中添加成膜促进剂可提高转化膜的生长速度，并且添加铵盐、氯化物后转化膜的铈含量从5.93%改变为4.15%和9.27%；还发现添加成膜促进剂铵盐、氯化物后转化膜耐腐蚀性提高为原来的2.6和5.6倍，其中后者的耐点滴腐蚀能力优于传统铬酸盐转化膜，并且还可将铝合金表面的显微硬度从HV68.8增大至HV389和HV450。
