摘要

高熵合金是近年来一种突破传统合金设计理念的新型多主元合金材料，在抗压强度、硬度、热稳定性、耐磨性、耐腐蚀性等方面具有显著优于常规金属材料的特质。冷喷涂作为一种固态沉积技术，在高性能涂层制备、零件修复与再制造和零构件增材制造等方面受到国内外的广泛关注，为高熵合金的制备提供了一种新的途径。通过分析国内外冷喷涂制备高熵合金的研究现状，重点阐述了冷喷涂高熵合金原料粉末制备、喷涂工艺参数优化、涂层显微组织结构及性能、粒子结合机制和后处理工艺等方面的进展，并对冷喷涂制备高性能高熵合金未来的研究方向提出了展望。

Abstract

High - entropy alloys are a kind of novel multi - principal component alloy that recently breaks through the design concept of traditional alloys, which were significantly superior to conventional metallic materials in compressive strength, hardness, thermal stability, wear resistance and corrosion resistance. Meanwhile, cold spray is a solid - state deposition technology, attracting great attention around the world in preparing high - performance coatings, repairing, and remanufacturing parts, and additive manufacturing parts and components, which could provide a new approach for preparing high - entropy alloys. In this work, by analyzing the research status of cold spraying high entropy alloy at home and abroad, the recent progress of cold spraying high - entropy alloys was reviewed from feedstock powders preparation, spraying process parameter optimization, microstructure and properties of coating, particle bonding mechanisms, and post - treatment processes. Besides, the future research direction of cold spraying high performance high - entropy alloys was also prospected.

Key words： cold spray; high - entropy alloy; coating; additive manufacturing
