Target in the shape of a cylinder for cathodic arc coating with continuous groove to control arc

摘要

A target in the shape of a cylinder (170) for providing a coating material in a cathodic arc coating system has a generally uniform depression (174) formed at the outer periphery (172). The depression (174) ensures that an arc from the coating apparatus (10) will move uniformly about the outer periphery (172) of the target (170), such that a coating cloud will also be uniformly applied to parts to be coated.
