Plasma Spraying

Expert solutions to help you succeed

Plasma spraying involves the spraying of molten or heat-softened material onto a surface to provide a coating, using inert gases as plasma gas and carrier gas. In plasma spraying process, the material to be deposited — typically as a powder, sometimes as a liquid, suspension or wire — is introduced into the plasma jet, emanating from a plasma torch. In the jet, where the temperature is on the order of 20,000 K or more, the material is melted and propelled towards a substrate. There, the molten droplets flatten, rapidly solidify and form a deposit. Typical plasma gases are argon, helium, nitrogen and hydrogen. Single gas or mixtures can be used.

Plasma Spraying Expertise and Solutions

  • Argon – key process gas for plasma spraying. Completely inert and easily ionized, and it can be used as the primary plasma gas or as a secondary gas with nitrogen to increase its energy. Also used as a powder carrier gas.
  • Hydrogen – used as a process gas in atmosphere plasma spray applications.
  • Helium – high heat transfer coefficient and thermal conductivity; also used as a secondary gas with argon in plasma spray applications.
  • Nitrogen – a variety of uses in thermal spray processes, particularly as a carrier gas.
  • Decades of experience – our application engineers can help you select a supply system to meet your pressure and volume requirements.
