Method and apparatus for vaporizing materials by plasma arc discharge

摘要

In order to ignite a vaporizing arc on a target which includes at least at its surface a material of a high melting point to be vaporized, and to stabilize and guide same, an electron beam gun or a laser is forseen for generating of a local vapor cloud or a premelted spot on the surface of the target in order to therewith ignite and guide the arc spot.
