It was found that the compositionuniformity depends on the shape coefficient of fusion zone, and the later is a func-tion of both power density and interaction time. If the power density is certain va-lue, it is proportional directly to the interaction time. A complete uniformal moltenpool can be gotten, when the shape coefficient is between 1.6 and 3.0. Key words： laser alloying    composition uniformity    shape coefficient of molten pool 收稿日期: 1990-02-18      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 梁勇 曾晓雁 佟百运 斯重遥 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1990/V26/I2/120 1 Chande T, Mazumder J.
