Advancing Surface Hardness and Wear Resistance: Microwave-Assisted Cladding of Ni-TiC Mixture onto SS-304

This study focuses on enhancing surface hardness and wear resistance through microwave-assisted cladding of a Ni-TiC mixture onto SS-304 substrates. Meticulous preparation steps were employed, including substrate cleaning and preheating of the coating material, to ensure optimal adhesion and prevent defects. Microwave hybrid heating (MHH) was utilized to facilitate rapid and uniform heating, enhancing the efficiency of the coating process. A scanning electron microscope (SEM) image revealed a uniform cladding layer devoid of cracks, indicating successful deposition and consolidation. Surface hardness was improved by 46.87%, demonstrating a significant enhancement in mechanical properties. The measured wear rate and coefficient of friction provided critical insights into the surface’s wear resistance and frictional behavior. Overall, this study highlights the efficacy of microwave-assisted cladding in improving the performance and durability of SS-304 substrates, with implications for various engineering applications requiring enhanced surface protection and mechanical properties.
