中文摘要
鑽石具有高硬度、高絕緣性及高崩潰電壓等優越的特性,然而其缺點為不易被加工。鑽石為非導體,故無法以一般的放電加工法進行加工,所以本研究使用鎳基鑽石顆粒複合鍍層,以鎳為基材夾持鑽石顆粒。再以單發放電方式,探討電弧放電之後的鎳基鑽石顆粒複合鍍層及鑽石顆粒電損傷型態變化。
實驗結果發現,當鑽石顆粒位於電損傷區域較中心位置時,由於鑽石顆粒的阻擋使得原本集中的電弧散開,會使電損傷區域增大。當鑽石顆粒位於電損傷區域較邊緣位置時,阻止了熔融鎳基材向四周的噴濺使電損傷區域減小。當脈衝電壓條件小於300V,或鑽石顆粒位於電損傷區域較邊緣位置時,鑽石顆粒的電損傷輕微,表面變的圓滑且有小裂縫產生,表面殘留噴濺的熔融鎳液滴。脈衝電壓大於300V,且鑽石顆粒位於電損傷區域較中心位置時,鑽石顆粒的電損傷嚴重,表面呈現碎裂狀,凸起的邊緣呈現類似片狀的剝落。
Abstract
Diamond has superior characteristics, such as high hardness, high isolation, and high breakdown voltage, but it is also difficult to manufacture for industrial application. Because diamond is a nonconductor, the usual electrical discharge machining (EDM) method cannot be used. Hence, this study uses the plating nickel to keep the diamond powder as the composite electroplated layer of nickel-diamond powder. The variation of the composite layer and the diamond particle erosion characteristic after arc discharge can be realized by single-arc discharge.
By the result of experiment, it can be known that the erosion area will be enlarged when the diamond particle is near to central erosion area, because the diamond that has good heat stability makes plasma to spread. The erosion area will be decreased when the diamond particle is near to edge of erosion area, because it stops the melted nickel to spread. The surface of diamond particle is broken slightly that the particle become more spherical and has some nickel remain on it when pulse voltage is less than 300 volt or the diamond particle is near to edge of erosion area. The surface of diamond particle is broken seriously that the particle is cracked to pieces when pulse voltage is more than 300 volt or the diamond particle is near to central erosion area.
