Iron-base fluxed alloy is produced by adding suitable amount of boron and silicon into iron-carbon alloy, which is usually used on the wearable and weak-acid-medium proofing accessories under 500℃. Although the performance of iron-base fluxed alloy can not match with that of the nickel or cobalt alloy, it has wide source materials and low prices, which is the great advantage for application.

铁基自熔性合金是铁——碳合金中加入一定量的硼、硅元素制成的，通常应用在常温——500℃以下耐磨损、耐弱酸腐蚀介质的机械零部件上，仅管铁基自熔性合金，综合性能不如镍、钴基合金，然而原料来源广泛，价格便宜，这是其得以普及应用的较大优势。

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。
