摘　　要：采用硼砂盐浴的方法进行TD处理,得到碳化物涂层,用X射线衍射仪、扫描电镜、显微硬度仪及划痕法测量了涂层的组织和性能。结果表明,所得的涂层物相结构单一,均匀致密,显微硬度高达3200HV,涂层与基体是冶金结合,结合力强。A surface layer of carbide was gained in the fused borax bath. The microstructure and performance were investigated by XRD, SEM, microhardness instrument and scarification. The results show that the phase structure of coating is single and dense. The microhardness arrives to 3200HV. The coating bonds substrate with metallurgical bonding. The binding force is strong.
