真空电弧点火法是一项日本发明专利.其要点为:将被处理物作为阴极(此阴极可在真空电弧装置中进行来回移动),在上游部安设一个电弧点火装置,这样上游部的被处理物就可借助阳极进行不间断地连续点火,即使被处理物移动至下游部亦无妨.本真空电弧点火方法的优点是:被处理物的移动速度不受限制;不受被处理物表面任何特性的限制. The vacuum arc ignition method is a Japanese invention patent, which has the following points: The object to be processed is used as a cathode (this cathode can be moved back and forth in the vacuum arc device), and an arc ignition device is installed in the upstream part so that the upstream part The processed object can be continuously and continuously ignited by the anode, and the object to be processed is moved to the downstream portion. The advantage of the vacuum arc ignition method is that the moving speed of the object to be processed is not limited and is not affected by any Characteristics of the restrictions.
