摘要

The present study investigates high-chromium heat-resistant steel matrix composite (SMC) reinforced with WC tool tip scraps to enhance the wear resistance of the material. The wear rate and microstructure of the fabricated SMC using an in situ casting technique were examined in this study. Microstructural analysis revealed that the grain boundaries of the base metal increased, albeit not significant, with increasing distance from the WC tool tip scraps. A mechanical bond was formed between the WC tool tip scraps and the high-chromium heat-resistant steel due to the presence of WC particles from the main body, which facilitated fluid infiltration into these WC particles. High-chromium heat-resistant steel with the addition of the WC tool tip scraps demonstrated superior wear resistance compared to the steel without reinforcement of WC tool tip scraps. The highest wear resistance was achieved in the sample reinforced with seven pieces of WC tool tip scraps.
