摘要

•Innovative fabrication of a < NiCrAlY-IN625> system by SLM was demonstrated.•Several criteria were used to select the most appropriate SLM process conditions.•As-built coatings exhibited significant dilution characteristic of SLM remelting.•Laser power P = 250 W and scanning speed v = 800 mm/s were found optimal.
