Abstract

The advancements in materials and surface modification methods have gained significant attention in various industrial applications. In this study, we investigate the efficacy of ceramic-coated SS304 by depositing a coating consisting of 8 % Yttria Stabilized Zirconia (YSZ). This paper explores the application of ceramic coatings, particularly 8-YSZ, onto SS304 substrates at thicknesses of 50 microns and 100 microns. Microhardness tests reveal a direct correlation between coating thickness and hardness numbers, with the coated substrate exhibiting a higher hardness, up to 1.6 times greater than the uncoated substrate. The coating process significantly enhances mechanical strength, surpassing the uncoated substrate. Wear analysis shows that as the coating thickness increases, the wear rate decreases by up to 40 % compared to the substrate material, indicating the effectiveness of thicker coatings in mitigating wear and enhancing substrate durability. Microstructure tests before and after wear provide insights into structural changes induced by wear phenomena, elucidating the evolution of microstructural features under abrasive conditions. The findings highlight the critical role of engineering materials, particularly zirconia-based ceramic (8-YSZ), in improving the mechanical properties and wear resistance of substrates through coating applications.
