It showed that the co-filtration of steel surface carbonitride together with rare earth, as an active element, leads to result microalloying . The carbonitriding rate may be accelerated up to 20—25% with improved quality of concentrated case. 收稿日期: 1986-03-18      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 韦永德 陈刚 刘金香 高秀英 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I3/132 1 Waudby, P.E., Int.
