Abstract: The research progress of FeCoNiCr high-entropy alloy coatings prepared by atmospheric plasma spraying is reviewed, and the research progress of alloy components selection, spraying technology, coating structure and properties, and post-treatment technology are summarized in detail. Several problems such as the immature optimization of existing spraying process, the insufficient design of coating composition and the lack of research on the structure and properties are proposed, and the research directions and routes are put forward in a targeted manner, which provides reference and guidance for the follow-up research, application and development of FeCoNiCr high-entropy alloy coatings.
