WORKPIECE WITH SURFACE PRE-TREATED PRIOR TO SPUTTERING, PRE-TREATMENT METHOD OF WORKPIECE SURFACE PRIOR TO SPUTTERING AND PRE-TREATMENT DEVICE OF WORKPIECE SURFACE PRIOR TO SPUTTERING

摘要

FIELD: metallurgy.SUBSTANCE: workpiece with treated surface includes parts in the form of grooves and parts in the form of flanges, which are formed in turn on the workpiece surface. Besides, the workpiece has uneven surfaces formed on tops of parts in the form of flanges and small-roughness sections being smaller than uneven surfaces and formed by treatment on parts in the form of grooves among alternatively formed parts in the form of flanges and parts in the form of grooves.EFFECT: improvement of adhesion of a coating to surface.29 cl, 18 dwg
