The chemical composition of coating and the distribution of Ce and La along the depth beneath the surface of the steel specimens have been analyzed by ion-probe, SEM energy spectrum and fluorescent X-ray. It is shown that RE is remarkably influenced upon the carbonitriding process. 收稿日期: 1983-05-18      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 刘志如 王春义 范爱龄 程建民 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I5/121 1 Stephens, J.
