| 摘 要： | 利用等离子熔覆技术,在钢基体表面熔覆了一层铁基合金,获得了与基体呈冶金结合的、性能良好的涂层;采用金相显微镜对熔覆层的组织进行观察,发现熔覆层整体组织由柱状树枝晶向等轴晶转变,无气孔、夹杂,其中枝晶组织粗大,等轴晶组织细小;利用显微硬度计分析表明,熔覆层具有较高的硬度,并且由表面到基体呈梯度分布;磨损试验结果表明熔覆层的耐磨性是淬火45钢的2.56倍.

| Abstract: | In the paper, plasma cladding processing was performed using Fe - based powder on steel substrate. The coating obtained is well bonded with the substrate. The microstructure and properties of the coating have been analysed. There is no void and inclusion in the layer. The arborescent structure is coarse and equiax crystal is minute. The microhardness of the coating is high and the wear resistance of the coating is as 2. 56 times that of quenched 45 steel. |
