Controlled Atmosphere Plasma Spray Systems

Controlled Atmosphere Plasma Spray Systems

These systems operate in a controlled atmosphere, producing coatings that are dense, oxide-free, and very pure. Because of these properties, applications include land-based and in-flight turbine components and medical implants using metallic, ceramic, and cermet materials.

Our portfolio of controlled atmosphere plasma spray systems is comprised of:

  • Vacuum Plasma Spray (VPS)
  • Low Vacuum (LVPS) / Low Pressure (LPPS) Plasma Spray
  • Low Pressure Plasma Spray-Hybrid (LPPS-Hybrid)

The presence of oxygen can undesirably affect coating characteristics. Spraying materials in a controlled atmosphere ensures coatings are very pure, dense, and oxide-free. Prior to coating, components are preheated and cleaned to reduce coating stress and ensure a clean, oxide-free substrate. Many types of surface protection can be achieved with controlled atmosphere plasma spray, such as:

  • Oxidation
  • Hot corrosion
  • Chemical attack
  • Erosion
  • Wear
  • Electrical resistance
