Development of low friction coating films containing free carbon and their application to machining difficult-to-machine materials.

本研究以非平衡磁控溅镀法制备低摩擦薄膜，并应用于难加工材料的高速铣削加工。UBMS涂层，特别是UBMS-TiCN涂层具有更光滑的表面，没有液滴和更低的摩擦系数比任何其他AIP涂层工具研究。UBMS-TiCN薄膜的润滑能力降低了切削力、切削温度和切屑的粘附，从而获得长的刀具寿命和良好的加工表面。

In this study, some low friction coating films by Unbalanced Magnetron Sputtering(UBMS) method are developed, and are applied to high-speed milling of difficult-to-machine materials. The UBMS coated films, especially UBMS-TiCN have smoother surface without droplets and lower friction coefficient than those of any other AIP coated tools studied. The lubricating ability of the UBMS-TiCN film reduces the cutting force, cutting temperature and adhesion of chips, so that long tool life and good finished surface are obtained.
