Abstract:
A method of etching PVD-coated stainless steel, may include machining to form irregularities on a surface of a steel member; coating the steel member by providing a coating layer on crests of the irregularities but not on throughs, the coating layer imparting color and texture to the steel member; masking in which the surface of the steel member is partially provided with a masking layer such that the surface of the steel member includes a masking area and an exposed area; and etching the coating layer provided on the exposed area to remove the coating layer.

Claim (Index 1):
A method of etching physical vapor deposition (PVD)-coated stainless steel, the method comprising:\n machining a steel member to form irregularities on a surface of the steel member; coating the steel member by providing a coating layer on crests of the irregularities but not on throughs of the irregularities, the coating layer imparting color and texture to the steel member; masking the steel member, wherein the surface of the steel member is partially provided with a masking layer and the surface of the steel member includes a masking area and an exposed area; and etching the coating layer provided on the exposed area to remove the coating layer, wherein the etching is started from the throughs of the irregularities to the crests of the irregularities to corrode the coating layer such that the coating layer provided on the crests of the irregularities is removed.
