The feasibility of fairly uniform surface alloying using high-power continuous lasers has been firmly established.1-3 Experimental studies have produced highly alloyed beads,1 while limited data on the effect of traverse speed on the depth, width, and solute content of the alloyed bead are available.3 Important questions remain unanswered, however,4 and more experimentation is required to examine the nature of the interactions between the process parameters, to establish the reproducibility, and to clarify the role of fluid flow in the molten pool.
