Abstract：Ceramic powders of Al2O3 and TiC are coated with a layer of cobalt. Successfully the hot-pressed Al2O3-TiC-Co(ATC) modified ceramic possesses improved mechanical properties. Especially its bending strength and fracture toughness are much higher than that of Al2O3-TiC (AT30) ceramic. The abrasion wear behaviour, mechanisms and wear resistance of ATC and AT30 ceramics are compared and studied. The results show that ATC ceramic possesses driproved wear resistance. 收稿日期: 1998-03-18      基金资助:国家自然科学基金!59332060 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 郦剑 茅东升 黄立萍 郭绍义 毛志远 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1998/V34/I3/332 1Culter R A, Hurford A C.
