摘要
提出了一种全新的工程陶瓷经济型加工方法。自行研制了高频引弧微爆炸加工电源和冲击波发生器,利用高频引弧效应诱导电极微爆炸产生的具有高温和高能量密度的轰击波加工工程陶瓷。在一定的电参数和轰击参数条件下,成功地在陶瓷试件上加工出通孔和矩形槽。对加工后的陶瓷试件进行了SEM分析、能谱分析和X射线衍射分析,发现轰击后的试件表面存在易加工的变质层。高频引弧微爆炸加工方法的加工机理包括高温气化、氧化和分解去除,以及爆轰冲击去除。
A novel economical method was advanced for ceramic materials processing by micro-- explosion of arc ignition. The power supply of micro--explosion in high frequency arc ignition and shock wave generator were developed. During the micro--explosion in high frequency arc ignition, the shock wave with high temperature and high energy density were generated, and the shock wave was used for ceramics processing. Through hole and rectangular notch were machined successfully in the definite parameter by this method. The metamorphic layer which can be machined easily was found after SEM analysis, spectroscopy analysis and X--ray diffraction analysis. The machining mechanism includes high temperature gasification, oxidation, decomposition and detonation.
