| 摘 要： | 通过在D256焊条药皮中加入钛铁、钒铁、石墨、稀土等,利用焊接电弧冶金反应在金属堆焊层中自发生成碳化物增强颗粒以提高其耐磨性。实验结果表明:含碳化物颗粒的金属堆焊层具有良好的耐磨损性能,其单位面积磨损质量损失仅为D256焊条相应金属堆焊层的约1/3,该耐磨堆焊材料的堆焊层组织为奥氏体组织和弥散分布于基体中的硬质碳化物颗粒,从而有利于显著提高金属堆焊层的抗磨性能。

| Abstract: | With addition of ferrotitanium,ferrovanadium,graphite,rare earth,etc,in electrode coating of D256,the carbide particles was spontaneously generated by welding arc to improve wear resistance of metal surfacing layer.The experimental results show that the metal surfacing layer which contains carbide particle has good wear resistance and is about 1/3 of wearing quantity in unit area in comparison with D256.Microstructures of metal surfacing layer are austenite and dispersively distributed rigid carbide particl... |
