FIELD: process engineering.
SUBSTANCE: invention relates to sputtering made for attaching preset properties, for example, high adhesion, durability. Microrelief is created by four tandem rollers with milled-out triangular teeth located at forty degrees to roller axis. Tandem roller teeth are shifted relative to each other by tooth pitch P=0.5. Note here that two of said tandem rollers have their teeth directed to the right while other two rollers have their teeth directed to the left.
EFFECT: simplified process, higher adhesion between microrelief and substrate and fatigue strength.
