Coating system for plastic processing applications

A multi-layer coating exhibiting good corrosion resistance and good abrasion resistance, comprising a layer A and a layer B deposited in a sequence of formation of A/B/A/B/A/A, where layer A is a CrN-based layer or a CrN layer and layer B is a CrON-based layer or a CrON layer, where the multi-layer coating exhibits a modulation ratio of the thickness of the layers A and B in such a way that the thickness of the layers A and B is less than the thickness of the layers A, B, C, B, C, B, C, B, C, B, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, C, the multi-layer coating comprises at least two different coating portions over the entire thickness of the multi-layer coating, with different tuning ratios of the thickness of the A layer and the B layer. 一种表现出良好的耐蚀性和良好耐磨性的多层涂层，该多层涂层包括按照形成类型为...A/B/A/B/A...顺序的方式沉积的层A和层B，层A是基于CrN的层或CrN层，层B是基于CrON的层或CrON层，其中，所述多层涂层按下述方式表现出A层和B层的厚度的调制比，即，所述多层涂层包括在整个多层涂层厚度上的至少两个不同的涂层部分，其中有A层和B层的厚度的不同调节比。
