Various Ceramic-Based Coatings on High-Speed Steel (HSS) Substrate: Mechanical and Tribological Properties

Abstract

In modern times, tribology plays a significant role in energy degradation, primarily due to friction, which leads to substantial energy loss and material degradation. Coating is a highly viable technique to reduce this impact. In this paper, ceramic-based coatings, specifically oxide and non-oxide types, are considered for mechanical and tribological use with a high-speed steel (HSS) substrate. Ceramic coatings are vital to HSS cutting tools from mechanical and tribological damage. A comprehensive surface morphology of coatings and mechanical and tribological properties, such as hardness, elastic modulus, surface roughness, wear rate, and coefficient of friction, are thoroughly investigated. The findings indicate that ceramic-based coatings significantly enhance the lifespan and efficiency of HSS tools, making them indispensable in high-performance machining and cutting tool industries.
