The invention discloses a high-
hardness and low-friction multi-layer composite cutter
coating and a preparation method thereof.The high-
hardness and low-friction multi-layer composite cutter
coating is prepared through a multi-arc
ion plating and high-power pulse magnetron
sputtering co-deposition technology and structurally comprises a Ti base layer, a
TiN transition layer, a TiSiN hard supporting layer and a TiSi-DLC anti-friction layer, and the TiSiN hard supporting layer and the TiSi-DLC anti-friction layer are alternately deposited. According to the high-
hardness and low-friction multi-layer composite cutter
coating and the preparation method thereof, through the alternate deposition design of the coating, the
internal stress between
layers is effectively balanced, the
binding force between the coating and a base body is improved, the
surface modification requirement of an industrial
cutting tool is met, meanwhile, the comprehensive
mechanical property of the coating is further improved by changing the modulation period, and the service life of the coating is prolonged. The popularization value is realized.
