The deformation and spreading of fully molten particles impacting onto a rough surface have been investigated by numerical simulation. A numerical technique, based on finite element analysis, was developed specifically for this simulation. The Lagrangian method with an automatic remeshing technique has been used to trace accurately the free surface of the molten matter and to improve the accuracy of the computation. A friction limiting condition at the particle substrate interface was introduced to describe the effects of the substrate surface roughness. This surface characteristic significantly influences the flattening degree, the flattening time, the spreading velocity of the liquid particle and its final shape.

This paper is devoted to the investigation of the transient pressure occurring at the impact of a molten particle onto a flat substrate surface under different thermal spray conditions. In this paper, the mathematical model developed is based on the following assumptions: laminar, viscous and incompressible fluid; the mixed velocity-pressure model is employed to construct the finite element model. The choice of pressure penalty coefficient, which depends on the Reynolds number, is crucial for the results. This is discussed in this paper. The numerical results show that the pressure at the particle-substrate interface is strongly affected by the processing parameters, especially by the particle density and the impact velocity. The influence of spray parameters and material properties are also discussed.
