| 摘 要： | 针对秸秆压块机模块磨损失效问题,分析了模块失效机理,提出了采用电弧喷涂3Cr13丝材对秆压块机模块表面进行强化和修复新工艺。采用正交试验和极差分析法研究了喷涂电流、喷涂电压、喷涂距离、喷涂气压对涂层耐磨性的影响规律,优化了压块机模块电弧喷涂3Cr13工艺参数,测试了3Cr13涂层的摩擦系数。结果表明:涂层摩擦系数为0.36,远低于铸钢摩擦系数0.8,涂层具有优异的耐磨性。

| Abstract: | Considering the wear failure problem of the straw cuber,failure mechanism of its briquette was analyzed and a new surface strengthening process of arc-sprayed 3Cr13 coatings was proposed.Influences of the arc-spraying technological parameters,including spraying current,spraying voltage,spraying distance and spraying pressure,on wearing resistance were studied by range analysis and orthogonal experiments,the technological parameters for arc-spraying 3Cr13 coatings were optimized,and coefficient of friction of the coatings was tested.The results indicated that the coefficient of friction of the coatings(0.36) was much lower than steel-cast(0.8),and the coatings performed excellent wear resistance. |
