Flattening behavior of the metallic particles plasma sprayed onto flat substrate surface was systematically investigated by changing both substrate temperature and ambient pressure in the chamber, independently. Transition phenomenon from a splashing splat to a disk splat in the flattening pattern for each particle material was recognized both by changing the substrate temperature and the ambient pressure. The relation between fraction of disk splat and both substrate temperature and ambient pressure was summarized as a three dimensional transition curvature for each sprayed material and the relationship between physical properties of the materials sprayed and character of 3-D curvature was investigated.
