The effect of Gr on microstructure, mechanical properties, and corrosion resistance of the HEAs is studied. The experimental results indicate that the main microstructure of Gr/CoCrFeNiTi HEAs is equiaxed grains, with precipitated phases filled between the grains. Graphene plays a role in refining grains. The Gr/CoCrFeNiTi HEAs composite coating consists of the face centered cubic (FCC), body centered cubic (BCC), and M<sub>23</sub>C<sub>6</sub> in-situ formed carbides. Graphene ptroduces the effect of promoting the formation of BCC and M<sub>23</sub>C<sub>6</sub> carbides. The coatings hardness tends to increase with the increase of Gr addition, and the hardness is closely related to solid solution strengthening, fine grain strengthening, and dispersion strengthening. As Gr increases, the both wear resistance and corrosion resistance increase first and then decrease. The hardness, Gr, and the content of hard and brittle carbides in the coating have impact on the wear resistance.</p></div>","PeriodicalId":663,"journal":{"name":"Journal of Russian Laser Research","volume":"44 5","pages":"590 - 596"},"PeriodicalIF":0.7,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138525128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
