摘　　要：在镐形截齿受力分析的基础上,利用先进的等离子束表面冶金技术,从截齿的结构和材料两方面入手对截齿生产工艺进行了改进,并对新工艺生产的截齿的组织性能进行了测试分析。研究结果表明,等离子束表面冶金技术在采煤机截齿上具有很高的应用价值。On the basis of analyzing the stress of cutting picks by using the finite element software of ANSYS,plasma surface plating was employed to improve process of production of cutting picks in both structure and material design. The microstructure and performance of improved cutting picks were tested and analyzed. Results show that the new technology has high application value.
