摘要(Abstract)：

以Ni-Mo-Si-C-Ti混合粉末为原料,利用等离子熔敷技术在Q235基材表面原位合成了以MoSi_2和TiC为增强相,以γ-(Ni,Fe)为主要基体相的耐磨抗高温氧化复合涂层。利用XRD、OM、SEM、EDS分析了涂层及氧化膜的显微结构和相组成,测试了涂层在1000℃恒温氧化条件下的抗氧化性能。结果表明:涂层组织致密、细小,具有快速凝固显微组织特征,与基材呈良好的冶金结合;涂层显微组织为不规则块状初生相MoSi_2和颗粒状TiC金属陶瓷初生相弥散分布于强韧性良好的γ-(Ni,Fe)过饱和固溶体基体上;涂层氧化膜主要组成相为SiO_2、TiO_2和少量Fe_2O_3,氧化动力学曲线近似符合抛物线规律,复合涂层具有良好的抗高温氧化性能。
