| 摘要: |
| 制备了由FeO4粉、Ni／Al粉和超细铝粉组成的FeO4基一次喷涂粉末，用抛光至镜面的试样研究了喷涂层的形成特征，用XRD、SEM对其等离子喷涂层的组织与相结构进行了分析。结果表明：FeO4基一次喷涂层中出现FeO4高温生成相Fe13Mo2B5，涂层与基体的结合为机械、微冶金结合；其结合强度比FeO4等离子喷涂层提高了93.2％，耐磨性比FeO4喷涂层提高了84％。 |

| Abstract: |
| One step plasma spray powders were synthesized with FeO4, Ni/Al and superfine aluminum powder. The polished mirror sample was used to investigate the formation characteristics of the coating, the micro- and phase structures were studied by XRD and SEM. The result showed that the high-temperature phase Fe13Mo2B5 occurred in the coating and the bonding of coating with substrate was mechanical and micro-alloying. The bonding strength of coating was 93.2% and its wear resistance was 84 % more than that of pure FeO4 coating. |
