摘要

This study investigates the effect of silicon carbide reinforcement on the hardness and wear resistance of stainless steel 304 L (SS304L) components fabricated using the WAAM process. SiC particles, known for their high hardness and excellent wear resistance, are incorporated into the SS304L matrix in varying weight percentages (1%, 2%, 3%, and 4%) to assess their influence on mechanical performance.The research follows a systematic approach, beginning with the fabrication of thin-walled SS304L components using the WAAM technique. During the deposition process, SiC particles are introduced into the molten pool to achieve uniform dispersion within the metallic matrix. The fabricated specimens are then subjected to extensive experimental testing to evaluate their mechanical behaviour. A series of tribological tests, including wear and hardness evaluations, are conducted to observe the effect of SiC reinforcement on the material’s performance. Optical microscopy, scanning electron microscopy (SEM), and Energy Dispersive spectroscopy are used to analyse the microstructural characteristics and particle distribution within the matrix. In this work, It was observed that Hardness improved by 128% and wear rate reduced by 30% with 4 wt% SiC reinforcement.The findings of this research will contribute significantly to the development of advanced metal matrix composites (MMCs) fabricated using WAAM. The enhanced properties achieved through SiC reinforcement make WAAM-fabricated SS304L components useful for demanding industrial applications like automotive, aerospace and marine engineering, where durability and resistance of wear are essential.
