摘要：

The inadequate wear durability of CoCrFeNiMo high-entropy alloy coatings poses great challenges to achieving reliable surface protection for engineering components. This study strategically addresses this limitation by incorporating ceramic carbide particles. The pure CoCrFeNiMo (P0), CoCrFeNiMo-10wt%Cr 3 C 2 (CrC10), and CoCrFeNiMo-10wt%B 4 C (BC10) composite coatings were deposited onto Q235 substrate utilizing laser cladding. Those coatings' structural characteristics, mechanical properties, tribological behavior, and wear mechanisms were an...
