There is a growing interest in use of the nickel-based alloy Inconel 625 coatings due to itsability to improve base materials high temperature properties. Thermal spraying methods such as AirPlasma Spraying (APS) can be considered as a convenient method to deposit this material. Thepresent work deals with APS deposited Inconel 625 structures consisting of huge number ofindividual splats formed by impacting molten droplets on substrates during spraying process. It isclear that the splat formation mechanism which dominates its size, cohesion, and boundaries highlyinfluences the microstructure of the coating. This paper presents a developed numerical techniqueperformed to simulate splat formation using a three dimensional model. In this method flow field issolved by Finite Volume Method (FVM) and free surfaces are determined from Youngs’ Volume ofFraction method (VOF). Finally, the model prediction is correlated with the actual splat geometries
