摘要

采用电沉积法在铜基体上制备了FeCoNiCrMn-WC高熵合金（HEA）涂层。系统研究了电解液中纳米晶WC含量（0 ~ 8 g/L）对合金微观结构、力学性能和腐蚀行为的影响。该涂层具有均匀致密的单面心立方相。关键研究结果表明，含6 g/L WC的涂层达到了最佳性能，最大显微硬度为689.3 hv，约为基体硬度的4倍，与不含WC的涂层相比，摩擦系数降低41.7%，磨损率降低46.3%。此外，它在3.5% NaCl溶液中表现出优异的耐腐蚀性。

Performance of FeCoNiCrMn-WC high-entropy alloy coatings fabricated by composite electrodeposition

FeCoNiCrMn–WC high-entropy alloy (HEA) coatings were fabricated on a copper substrate via electrodeposition. The influence of nanocrystalline WC content (0–8 g/L) in the electrolyte on the microstructure, mechanical properties, and corrosion behavior was systematically investigated. The coatings exhibited a single face-centered cubic (FCC) phase with a uniform and dense morphology. Critical findings indicate that the coating produced with 6 g/L WC achieved optimal properties, demonstrating a maximum microhardness of 689.3 HV—approximately four times higher than that of the substrate—along with a 41.7 % reduction in the friction coefficient and a 46.3 % decrease in the wear rate compared to the coating without WC. Furthermore, it exhibited superior corrosion resistance in a 3.5 % NaCl solution.

期刊介绍： This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys. The journal reports the science and engineering of metallic materials in the following aspects: Theories and experiments which address the relationship between property and structure in all length scales. Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations. Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties. Technological applications resulting from the understanding of property-structure relationship in materials. Novel and cutting-edge results warranting rapid communication. The journal also publishes special issues on selected topics and overviews by invitation only.
