(Al)TiSiN multi-layered coatings are promising candidates for use in processing of difficult-to-machine materials. In this study, AlTiN and three different Si-containing multi-layered coatings were designed to fabricate by arc evaporation technology to compare the effect of composition and structure on their microstructure, mechanical and tribological properties, oxidation behavior, and cutting performance. The results indicate that (Al)TiSiN G-3 (AlTiN + AlTiSiCN + AlTiSiCN/TiSiN + TiSiN) coating exhibits high adhesion strength (~87.3 N), low residual stress (~3.89 GPa) and high hardness (H ~ 34.2 GPa) combined with a high elastic modulus (E ~ 403.7 GPa) and a high ratio of H³/E*² (~0.21 GPa). (Al)TiSiN G-2 (AlTiN + AlTiSiN + AlTiSiN/TiSiN + TiSiN) and (Al)TiSiN G-3 had lower friction coefficients and wear rates than AlTiN and (Al)TiSiN G-1 (AlTiN + AlTiSiN) coatings due to a greatly reduction of abrasive wear. Oxidation resistance of the coatings was estimated in the following order: (Al)TiSiN G-1 > (Al)TiSiN G-2 > (Al)TiSiN G-3 > AlTiN. In addition, (Al)TiSiN G-3 coated tool possessed the optimal cutting performance in continuous and intermittent turning of 304 stainless steel due to the highest hardness and best toughness.

(Al)TiSiN 多层涂层是用于加工难加工材料的有前途的候选材料。在这项研究中，设计了 AlTiN 和三种不同的含硅多层涂层，通过电弧蒸发技术制造，以比较成分和结构对其微观结构、机械和摩擦学性能、氧化行为和切削性能的影响。结果表明，(Al)TiSiN G-3 (AlTiN + AlTiSiCN + AlTiSiCN/TiSiN + TiSiN) 涂层具有高附着力 (~87.3 N)、低残余应力 (~3.89 GPa) 和高硬度 ( H  ~ 34.2 GPa)结合高弹性模量 ( E  ~ 403.7 GPa) 和高比值H ³ / E * ²(~0.21 GPa)。(Al)TiSiN G-2 (AlTiN + AlTiSiN + AlTiSiN/TiSiN + TiSiN) 和 (Al)TiSiN G-3 具有比 AlTiN 和 (Al)TiSiN G-1 (AlTiN + AlTiSiN) 涂层更低的摩擦系数和磨损率大大减少磨料磨损。按以下顺序估计涂层的抗氧化性：(Al)TiSiN G-1 > (Al)TiSiN G-2 > (Al)TiSiN G-3 > AlTiN。此外，(Al)TiSiN G-3涂层刀具硬度最高，韧性最好，在304不锈钢连续和断续车削中具有最佳切削性能。
