提供增强的抗月牙洼磨损性能的AlCrN基涂层
摘要：
沉积在基材(201)表面上的涂层(210)，包括多层膜(216)，其由相互交替沉积的多个A层和多个B层组成，形成了A/B/A/B/A...结构，所述A层包含铝铬硼氮化物，而所述B层包含铝铬氮化物而不含硼，所述多层膜(216)至少包括初始部分(216a)和最后部分(216c)，其中，在所述初始涂层部分(216a)中的平均硼含量大于在所述最后涂层部分(216c)中的平均硼含量，并且所述初始涂层部分(216a)和最后涂层部分(216c)都显示出固有压应力，且其中在所述初始涂层部分(216a)中的固有压应力小于在所述最后涂层部分(216c)中的固有压应力。
摘要（英）：

A coating (210) deposited on a surface of a substrate (201) comprises a multi-layered film (216) consisting of a plurality of A-layers and a plurality of B-layers deposited alternating one on each other forming a A/B/A/B/A... architecture, the A-layers comprising aluminium chromium boron nitride and the B-layers comprising aluminium chromium nitride and not comprising boron. The multi-layered film (216) comprises at least a first portion (216a) and a last portion (216c), wherein the average boron content in the first coating portion (216a) is higher than the average boron content in the last coating portion (216c), both the first coating portion (216a) and the last coating portion (216c) exhibit inherent compressive stresses, and the inherent compressive stress in the first coating portion (216a) is lower than it in the last coating portion (216c).
