One method is to cover sliding components with materials that have low friction and wear characteristics. Surface functionalization is a fast-growing field emerging subject, owing to the need for surface modification being less expensive than designing and manufacturing a whole new material, and allowing the retention of some characteristics of the initial material, such as mechanical properties. Coatings are used as an alternative in the machining process to extend tool life, improve product surface quality, and speed up production. Multilayer coatings are particularly appealing among coating design concepts because they provide for more flexibility in tailoring surface qualities. For tribological performance improvement, the ability to regulate residual stress, hardness to elasticity modulus ratio, and substrate adherence, for example, by stacking coating layers, is advantageous. In this context, multilayer coatings have sparked a surge of interest as a feasible option for minimizing friction and wear. This paper looked at the properties of multilayer coating systems for tribological applications. The purpose of this work is to investigate the performance of coated tools in the machining process. Multilayer coating, nano-coating materials, and cutting tool are some of the terms used in this paper.
