为了减少磨损，从而提高微电火花加工（µ-EDM）的效果，采用了涂层电极。本文研究了掺硼CVD金刚石涂层的晶粒尺寸对微细电火花加工磨损性能的影响。实验结果表明，纳米晶涂层的放电坑比微晶金刚石涂层小，且放电坑周围存在熔融物质。这一发现将受到进一步调查。
In order to reduce wear and therewith enhance the microelectrical discharge machining (µ-EDM) results, a coated electrode was used. The paper presents the results of investigations into the influence of grain size of the boron-doped CVD diamond coating on the wear behavior in microsinking EDM. Experimental investigations show that nanocrystalline coatings exhibited smaller discharge craters compared to those for microcrystalline diamond coatings, and microcrystalline coating showed melted material around the discharge crater. The finding will be subjected to further investigations.
