A splat shape of most metallic and ceramic material onto a flat substrate surface has a transitional changing tendency from a distorted with splash to a lenticular without splash at a narrow temperature range with an increase of the substrate temperature. It has estimated from our results that the physical wetting strongly affects the transition behavior with the change of the substrate temperature. In this study, the effect of surface morphology of the substrate on the flattening behavior of thermal sprayed particle onto substrate surface was fundamentally investigated. The relation between the flattening behavior of the particle on the substrate surface and the surface morphology of the substrate was investigated. The morphology of the substrate was analyzed by Atomic Force Microscope : AFM and the surface roughness was evaluated as a quantitative characteristic of the substrate surface. Consequently, it was revealed that the surface roughness of the substrate in nm order significantly affects the shape of the sprayed particle. From the fact, it is inferred that the better wetting of the substrate by the flattening particle is induced by the surface roughness of the substrate.
