Characteristics of SUS 3O4/Ni-P alloy composite coatings sprayed on carbon steel substaretes were investigated by X-ray dffraction, EPMA analysis, hardness test, wear test and adhesion test between substrate and coating. And also interface structure between substrate and coating and or sprash particles west investigated by TEM observation. The obtained results are as follows.(1) Sprayed coatings consist of mixture of SUS3O4 splashes and Ni-P alloy splashes.(2) It can be seen from TEM diffraction pattern that a part of Ni-P alloy splashes are amorphized.(3) Hardness of composite coating increases with increasing Ni-P alloy content(4) Wear loss of composite coatings shows minimum in the range between 60 and 8O vol%Ni-P alloy content(5) Surface of coatings are smooth wity increasing Ni-P alloy content, while surface roughness is low.(6) 6Ovol%Ni-P alloy coating shows maximum adhesion strength between substrate and coaling.(7) All of the SUS 3O4/Ni-P alloy composite coalnigs are attackedin l0% HCl solution. Bad corrosion resistance is due to presence of pores and cracks in coatings.(8) Specimens for TEM observation can be made. But, interface between substrate and coating and or splashes were not distinguished.

采用X射线衍射、电子探针分析、硬度测试、磨损试验和结合力测试等方法研究了碳钢表面喷涂SUS 3 O 4/Ni-P合金复合涂层的性能。并通过透射电镜观察了涂层与基体的界面结构和飞溅颗粒。所得结果如下。(1)喷涂层由SUS 3 O 4飞溅物和Ni-P合金飞溅物组成。(2)从TEM衍射图可以看出，部分Ni-P合金飞溅物发生了非晶化。(3)复合镀层的硬度随Ni-P合金含量的增加而增加。（4）复合镀层的磨损量在Ni-P合金含量为60 ~ 80 vol%时最小。（5）随着Ni-P合金含量的增加，复合镀层表面光滑，但表面粗糙度较低。(6)60 vol %Ni-P合金镀层的结合强度最大。(7)所有的SUS 3 O 4/Ni-P合金复合镀层都附着在10%HCl溶液中。差的耐腐蚀性是由于涂层中存在孔隙和裂纹。(8)可制作TEM观察用试样。但是，基体与涂层和/或飞溅物之间的界面没有被区分。
