Thermal spray

Thermal spray is a surface modification technology which was designed so that the base material surface can withstand extremely harsh environments and conditions. The particles of molten powder, wire, or other material (metal, ceramic, cermet, or other), heated by a variety of heat sources until it is molten or nearly molten, are accelerated and sprayed onto the base material surface at high speed, forming a functional membrane.

Thermal spray

Features of thermal spray

  • Allows coating by ceramic, resin, or other materials, producing a high-quality composite membrane.
  • Does not damage the base material, and is unlikely to result in strain or other problems caused by heat.
  • Pores in the membrane provide thermal shock resistance and impregnating ability.
  • The thermal spray membrane thickness can be controlled as needed.
  • Repeated spraying of NEWSIC and other materials is possible, for a reduction in costs.
