Critical conditions were recognized both in the substrate temperature and the ambient pressure in the flattening of thermal sprayed particles onto the flat substrate surface. That is, the flattening behavior changed transitionally on the critical temperature and pressure .range, respectively. For those critical conditions, a transition temperature, Tt, and a transition pressure, Pt, were defined and introduced, respectively. Equivalence in the dependence both of transition temperature and transition pressure on the sprayed material's order indicated that the wetting of the substrate by the molten particle is a common domination in the flattening. Three dimensional transition map by combining both transition behavior in the flattening was proposed as a controlling principle for the thermal spray process.
