Notes:
Effect of both substrate temperature and ambient pressure on a flattening behavior ofthermal sprayed particles was systematically investigated. In the flattening of the sprayed particlesonto the flat substrate surface, critical conditions were recognized both in the substrate temperatureand the ambient pressure. That is, the flattening behavior changed transitionally on the criticaltemperature and pressure range, respectively. A transition temperature, Tt, and a transition pressure,Pt, for those critical conditions were defined and introduced, respectively. Equivalence in thedependence both of transition temperature and transition pressure on the sprayed material’s orderindicated that the wetting of the substrate by the molten particle is a common domination in theflattening. Three dimensional transition map by combining both transition behavior in the flatteningwas proposed as a controlling principle for the thermal spray process
