Abstract

High entropy alloys have attracted significant attention due to their exceptional corrosion resistance, which makes them excellent candidates for protective coatings on stainless steel substrates. This review critically examines the corrosion behavior of high entropy alloy coatings applied to stainless steel using various laser-based fabrication techniques. The focus is on the role of elemental and ceramic additions in enhancing the corrosion resistance of these coatings. By analyzing recent studies in detail, the review explores the synergistic effects of different elements on the microstructure, phase formation, and electrochemical performance of high entropy alloy coatings fabricated by various laser-based methods on different stainless steel substrates. The aim of this review is to provide insights into optimizing high entropy alloy coating compositions through laser fabrication processes to achieve superior corrosion-resistant coatings, thereby extending the service life of stainless steel components in corrosive environments.

元素添加对激光制备不锈钢高熵合金涂层耐腐蚀性能的影响

高熵合金由于其优异的耐腐蚀性而引起了人们的极大关注，这使得它们成为不锈钢基材保护涂层的优秀候选者。本文综述了采用各种激光加工技术对不锈钢表面的高熵合金涂层的腐蚀行为。重点是元素和陶瓷添加剂在提高这些涂层的耐腐蚀性方面的作用。通过详细分析近年来的研究成果，探讨了不同元素对不同激光方法在不同不锈钢基体上制备的高熵合金涂层的显微组织、相形成和电化学性能的协同作用。本综述的目的是通过激光加工工艺优化高熵合金涂层成分，以获得优异的耐腐蚀涂层，从而延长不锈钢部件在腐蚀环境中的使用寿命。图形抽象

期刊介绍： Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
