以TiFe粉、Cr粉、Ni粉、Fe粉、胶体石墨等为原料,利用合金粉粒埋弧堆焊技术在Q235钢表面原位反应合成TiC颗粒增强Fe基复合涂层.利用SEM,XRD和EDS等分析了涂层的显微组织,并在室温干滑动磨损条件下测试该涂层的耐磨性能.结果表明:利用合金粉粒埋弧堆焊技术,可以原位合成粒径在2 μm以下、弥散分布的TiC颗粒.涂层组织由TiC颗粒、马氏体和奥氏体构成.涂层平均显微硬度达601HV0.2,约是碳钢基体的3倍.由于TiC颗粒和马氏体的抗磨损性能使涂层具有优异的耐磨性能,因此涂层磨损质量约是基体金属的1/10.埋弧堆焊双层涂层与单层涂层相比,马氏体含量减少,奥氏体和TiC含量增加,耐磨性更好.
