Traditional binary or ternary nitride protective coatings are unable to achieve a coordinated improvement in terms of hardness, wear resistance, and structural stability. In this manuscript, a high-entropy composite nano-coating of CrWNbTaMoVSiN with an alternating structure of metal and nitride layers was prepared by using anode layer ion source-assisted magnetron sputtering technology. The influence of substrate bias voltage on the microstructure, phase structure, surface chemical state, friction and wear properties of coatings was systematically studied. The findings demonstrate that the substrate bias voltage has a substantial impact on the structure and performance of the CrWNbTaMoVSiN coatings. As the bias voltage increases, the coating deposition rate and thickness decrease, while the grain growth morphology gradually transitions from directionally aligned columnar crystals to equiaxed crystals. The primary phase of the coating is a solid solution with a face-centered cubic (FCC) crystal structure. At a bias voltage of 60 V, the coating exhibits a denser surface and cross-sectional microstructure, fewer structural defects, higher hardness, superior wear resistance, and enhanced electrochemical corrosion protection performance. This study provides critical experimental evidence and theoretical insights into the bias-voltage-dependent regulation mechanism of high-entropy nano-multilayer coatings, thereby supporting the process optimization of high-performance protective coatings and their engineering deployment under extreme service conditions.<\/jats:p>","DOI":"10.3390\/nano16181145","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T08:10:23Z","timestamp":1789373423000},"page":"1145","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Anode-Layer Ion Source-Assisted Deposition and Bias Voltage Tuning of CrWNbTaMoVSiN High-Entropy Nanostructured Coatings"],"prefix":"10.3390","volume":"16","author":[{"given":"Yan","family":"Ling","sequence":"first","affiliation":[{"name":"School of Physics Science and Technology, Lingnan Normal University, Zhanjiang 524048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shikun","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Physics Science and Technology, Lingnan Normal University, Zhanjiang 524048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Canxin","family":"Tian","sequence":"additional","affiliation":[{"name":"School of Physics Science and Technology, Lingnan Normal University, Zhanjiang 524048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changwei","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Physics Science and Technology, Lingnan Normal University, Zhanjiang 524048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"137","DOI":"10.1016\/j.jmapro.2026.04.065","article-title":"Exploration of SPS and cold-roll forming processes of Cu-Ag alloy applied in space conductive slip rings base on vacuum current-carrying tribological behavior","volume":"169","author":"Deng","year":"2026","journal-title":"J.
