Non ferrous metals , aluminium alloy ( LY12 ) and aluminium bronzes ( QAl 9 1 1 5 ), can be used as slot wedges of generator rotors . Their management and properties are mainly determined by suitable techniques of heat treatment .

有色金属材料铝合金（LY12）和铝青铜（QAl9115）用作发电机转子槽楔，其性能主要由合适的热处理工艺决定。

By using plasma arc method an Sn-P bronze hardfacing formed on steel 25 , which contains more strengthening phases . The wearing property of the friction pair consisted of Sn-P bronze and Cr-plated wheel is better than that of bronze QAl 9-4 and Cr-plated wheel .

25钢基体锡磷青铜合金粉末等离子孤喷焊层，含有较多的强化相，与镀铬轮组成摩擦副，耐磨损性能明显优于由QA19-4青铜和镀铬轮组成的摩擦副。
