Plasma Spray Coating


  • Plasma spray coatings allow your components performance to be highly enhanced.
  • Whatever criteria is important to you (heat barrier, corrosion protection, contamination reduction, osteocompatibility, component life... ) it can be improved, leading to higher equipement availability, longer component life and reduced equipment cost of ownership.
  • Our plasma torch are robotic to ensure maximum process repeatability.
  • Our engineering teams validate your specifications and needs and ensure adequate coatings to your applications.


  • Typical thickness: 50 to 3000 µm
  • Tunable Roughness depending on application: 5 µm to 30 µm Ra
  • Porosity: tunable from < 1%
  • Machining/polishing possible

Principle: a plasma gas is heated by an arc and accelerated through a shaped nozzle. This creates a plasma jet with a gas velocity up to Mach 2. Temperatures in the plasma jet are close to 10,000°C, which melts the respective material and allows it to be projected onto a surface where it cools and forms a layer.

Sprayed material: because of the versatility of plasma spray technology, a wide range of materials can be deposited. This ranges from low-temperature polymers up to metals, and also includes ceramics such as zirconia, yttria, aluminia, titanium- and chrome oxide, spinel and hydroxylapatite (Hap).

Properties of sprayed layers: adjustable thicknesses, roughness, porosity and purity, tailored to customer needs as ensured by our internal lab facilities.

Methodology: after the required specifications have been defined, Cleanpart implements the entire coating procedures that include tooling, surface preparation, controls and measurements, analytics and inline testing.
