Microstructures, phase compositions, mechanical properties and tribological behaviors of Cu-YB2C2 composites were investigated. The results indicated that Cu-YB2C2 composites had good chemical compatibility. Compared with pure copper, the hardness, tensile strength and wear resistance of Cu-YB2C2 composites were all significantly improved. Cu-10 vol% YB2C2 composites exhibited the highest tensile strength and the best tribological performance, with an ultimate tensile strength of 203 \u00b1 2 MPa and a wear rate of (3.1 \u00b1 0.4) \u00d7 10\u22128 mm3\/mm. The wear mechanism changed from adhesive wear to a combination of adhesive wear and abrasive wear with the addition of YB2C2, while surface oxidation and fatigue were also present in all tribosystems. Cu-YB2C2 composites have application prospects in electrical contacts and aerospace fields.<\/p>\n\n\n\n<p><strong>Keyword \/&nbsp;\u5173\u952e\u8bcd<\/strong><\/p>\n\n\n\n<p>Metal-matrix composites;Microstructure analysis;Mechanical properties;Wear<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"728\" src=\"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/10\/\u56fe\u7247-1024x728.jpg\" alt=\"\" class=\"wp-image-737\" srcset=\"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/10\/\u56fe\u7247-1024x728.jpg 1024w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/10\/\u56fe\u7247-300x213.jpg 300w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/10\/\u56fe\u7247-768x546.jpg 768w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/10\/\u56fe\u7247-1536x1092.jpg 1536w, https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-content\/uploads\/sites\/20\/2024\/10\/\u56fe\u7247-2048x1456.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"featured_media":737,"template":"","acf":[],"_links":{"self":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/paper\/736"}],"collection":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/paper"}],"about":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/types\/paper"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/media\/737"}],"wp:attachment":[{"href":"https:\/\/frontbasic.sslab.org.cn\/ceramics\/wp-json\/wp\/v2\/media?parent=736"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
