Embodiment 1
[0027] A kind of TiCrN&MoS 2 / Ti / Cr composite laminated coating tool, the tool is an ordinary milling insert, and its base material is: cemented carbide YT15. The deposition method is to prepare a combined coating by arc plating and intermediate frequency magnetron sputtering composite coating method, including a Ti target arc target, a Cr target arc target, and 2 MoS 2 Magnetron sputtering target: Arc ion plating deposits Ti transition layer and Ti / Cr transition layer for 4-5 minutes each, and then alternately deposits TiCrN coating (arc ion plating) with thickness of about 30-40nm and TiCrN coating with thickness of about 15-25nm MoS 2 / Ti / Cr coating (magnetron sputtering + arc ion plating), the final surface is MoS 2 / Ti / Cr lubricating coating, its preparation process is:
[0028](1) Pre-treatment: Polish the surface of the tool base to remove impurities such as oil stains and rust on the surface, then place them in alcohol and acetone in turn, and ultrasonically clean t...
Embodiment 2
[0040] A kind of TiCrN&MoS 2 / Cr / Ti laminated coating tool, the tool is an ordinary twist drill, and the tool base material is: high-speed steel W18Cr4V. The deposition method is to prepare a combined coating by arc plating and intermediate frequency magnetron sputtering composite coating method, including 1 Ti target arc target, 1 Cr target arc target, 2 MoS 2 Magnetron sputtering target: Arc ion plating deposits Ti transition layer and Ti / Cr transition layer for 4-5 minutes each, and then alternately deposits TiCrN coating (arc ion plating) with thickness of about 30-40nm and TiCrN coating with thickness of about 15-25nm MoS 2 / Ti / Cr coating (magnetron sputtering + arc ion plating), the final surface is MoS 2 / Ti / Cr lubricating coating, its preparation process is:
[0041] (1) Pre-treatment: Polish the surface of the tool base to remove impurities such as oil stains and rust on the surface, then place them in alcohol and acetone in turn, and ultrasonically clean them for ...
