Coatings are now frequently used on cutting tool inserts in the metal production sector due to their better wear resistance and heat barrier effect. Protective hard coatings with a thickness of a few micrometers are created on cutting tools using physical or chemical vapor deposition (PVD, CVD) to increase their application performance. Different coating materials are utilized for a wide range of cutting applications, generally in bi-or multilayer stacks, and typically belong to the material classes of nitrides, carbides, carbonitrides, borides, boronitrides, or oxides. The current study examines typical hard coatings deposited by PVD and CVD in the corresponding material classes. The present state of research is reviewed, and pioneering work on this subject as well as recent results leading to the construction of complete "synthesis-structure-property-application performance" correlations of the different coatings are examined. When compared to uncoated tools, tool coatings prevent direct contact between the workpiece and the tool substrate, altering cutting temperature and machining performance. The purpose of this paper is to examine the effect of cutting-zone temperatures on multilayer coating characteristics during the metal-cutting process. Simplified summary and comparisons of various coating types on cutting tools based on distinct deposition procedures. Furthermore, existing and prospective issues for the hard coating community are discussed.
由于具有更好的耐磨性和隔热效果，涂层现在在金属生产领域的切削刀具刀片上被频繁使用。通过物理或化学气相沉积（PVD、CVD）在切削刀具上形成厚度为几微米的保护性硬涂层，以提高其应用性能。不同的涂层材料被用于广泛的切削应用，通常为双层或多层堆叠，并且通常属于氮化物、碳化物、碳氮化物、硼化物、硼氮化物或氧化物等材料类别。当前的研究考察了通过PVD和CVD沉积在相应材料类别中的典型硬涂层。回顾了研究现状，并考察了该主题的开创性工作以及导致构建不同涂层完整的“合成-结构-性能-应用性能”相关性的最新结果。与未涂层刀具相比，刀具涂层可防止工件与刀具基体直接接触，从而改变切削温度和加工性能。本文的目的是研究金属切削过程中切削区温度对多层涂层特性的影响。基于不同沉积工艺对切削刀具上各种涂层类型进行简化总结和比较。此外，还讨论了硬涂层领域当前存在的问题和未来的问题。
