| 摘 要： | 针对当前秸秆压块机模块耐磨性差、易失效等问题,分析了模块失效机理,提出了采用等离子喷涂改善模块表面性能。通过试验,研究了电压、电流及喷涂距离等因素对材料耐磨性的影响,优化了等离子喷涂工艺参数。结果表明:喷涂电流的影响最为显著,其次是喷涂距离;等离子喷涂Ni60+50WC涂层后,试样的抗磨损性能大幅提高。

| Abstract: | In allusion to the problems of bad wear resistance and easy efficiency-losing,etc.of the current straw press block,the failure mechanism of the module was analyzed,a new technology on improving the properties of the module surface by plasma spraying was put forward.The effect of the voltage,electric current,spraying distance and so on on the material wear resistance was studied through test,the technological parameters of plasma spraying were optimized.The results show that the spraying current influences most significantly,and followed by the spraying distance;After the plasma spraying Ni60+50WC coating sample,wear resistance of the test sample increases greatly. |
