摘要

This study aims to resolve the critical issue of rapid corrosion failure in key components used in hot-dip galvanizing processes by developing an innovative WC-10CoCrFeNi cemented carbide incorporating TiCN additions. The research systematically examines how varying TiCN contents influence microstructure evolution, mechanical properties, wear behavior, and corrosion resistance in molten zinc environments. Experimental results demonstrate that introducing 1 wt% TiCN most effectively refines WC grains, producing the finest and most uniform microstructure. This optimal composition achieves peak mechanical performance with a hardness of 2106.14 HV and superior wear resistance, exhibiting a remarkably low friction coefficient of 0.246 and minimal wear rate of 2.472 × 10− 6 mm3·N −1·m −1. In corrosion testing, this material shows exceptional stability in molten zinc, with the lowest corrosion rate of 1.592 × 10 −3 mm/h. The enhanced performance mechanism involves both grain refinement strengthening and the formation of a continuous Cr-rich protective layer at the corrosion interface, which effectively impedes further zinc penetration. The corrosion process initiates through selective dissolution of the high-entropy alloy binder phase, followed by intergranular corrosion propagation, and culminates in surface spalling. These findings provide crucial insights for developing durable materials for galvanizing applications.
