【摘要】 研究了一种可在普通电火花加工机床上实现的金属工件表面涂层新方法。对其原理进行了探讨,并在实验基础上对涂层的特性进行了详细的分析。结果表明,用电火花加工的方法进行表面涂层可以明显改善金属工件的性能。在普通车刀上初步应用此种新方法,切削实验结果表明,涂层车刀的寿命较未涂层车刀的寿命提高一倍以上。更多还原

【Abstract】 A new method of surface modification of metal workpiece by ordinary electrical discharge machining(EDM) tool is described.Its principle of this surface modification method is studied.Based on the experiments,the characteristics of the coating are discussed in detail and the result shows that the metal workpiece characteristics are improved evidently by using EDM.The technology is applied to the ordinary cutting tools successfully.Through the cutting test,compared to the non-coated tool,the life of the coated tool is improved over one time.更多还原
