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      Received:  18 February 1990      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1990/V26/I2/120 1 Chande T, Mazumder J.
