DEVICE FOR EVAPORATING MATERIAL BY MEANS OF A VACUUM ARC DISCHARGE AND PROCESS

摘要

Deg. of ionisation of vapour produced for surface coating by vacuum arc discharge with consumable cold cathode and hot anode is controlled by preventing straight-line current flow between the operating surface (3a) of the material to be evaporated on the anode (14) by providing a movable wall (6) between them, having a window (6a) to ensure current flow between cathode and anode. ADVANTAGE - Adhesion of coating can be controlled.
