摘要
研究了La(NO_3)_3对Ni-Fe-La合金镀层的耐蚀性、高温抗氧化性、硬度、微观形貌和成分的影响。结果表明:随着La(NO_3)_3的质量浓度的增加,Ni-Fe-La合金镀层的耐蚀性、高温抗氧化性、硬度均得到明显提升,并且在La(NO_3)_3的质量浓度为0.4g/L时达到最优;Ni-Fe-La合金镀层结晶细致、结构紧密,其中含稀土La。
Effect of La resistance, hardness, micr （NO3）3 on the corrosion resistance, high-temperature oxidation o-morphology and component of Ni-Fe-La alloy coating were studied. Results showed that the corrosion resistance, high-temperature oxidation resistance and hardness of Ni-Fe-La alloy coating was obviously improved with the increasing of La （NO3）3 mass concentration. When the mass concentration of La（NO3）3 was 0.4 g/L, the corrosion resistance, high-temperature oxidation resistance and hardness of Ni-Fe-La alloy coating was the best. Ni-Fe- La alloy coating was fine and compact, coating contain rare earth La.
