Discuss Repair CoatingProcess Overview
What Is Plasma Spray Coating?
Plasma spray coating is a thermal spray process that uses a high-temperature plasma jet to melt powder materials. Molten or semi-molten particles are projected onto a prepared substrate surface, where they solidify and build a protective or functional coating system.
Plasma spray is especially suitable for ceramic coatings, oxide coatings, thermal barrier coatings and selected high-melting-point materials where surface performance is more important than changing the base component.
Typical purposes include plasma coating for wear resistance, thermal barrier coating performance, electrical insulation coating, oxidation resistance, surface restoration and application-specific surface engineering.

Materials
Plasma Spray Coating Materials
Material selection is one of the most important decisions in a plasma coating project. APT Coating helps evaluate the substrate material, operating temperature, wear mechanism, corrosion environment, required surface finish and inspection requirements before recommending a coating system.
| Material Type | Typical Materials | Common Purpose |
|---|---|---|
| Ceramic Coatings | Alumina, zirconia, chromium oxide | Wear resistance, electrical insulation, thermal protection and chemical stability |
| Thermal Barrier Coatings | YSZ and zirconia-based ceramics | Heat insulation for turbine, engine and high-temperature components |
| Oxide Coatings | Al2O3, Cr2O3, TiO2-based coatings | Wear resistance, dielectric protection, oxidation resistance and surface stability |
| Metallic Coatings | Nickel alloy, stainless steel, molybdenum | Surface restoration, dimensional build-up, repair and corrosion protection |
| Functional Coatings | Insulation, sealing, friction control and application-specific coating systems | Special surface functions based on operating conditions |
| Selected Wear-Resistant Coatings | Carbide or composite coatings when suitable | Wear and erosion resistance depending on process selection and coating requirement |
For dense carbide wear coatings, HVOF or D-Gun may be recommended depending on the part geometry, coating specification and working condition. APT Coating can help compare the most suitable thermal spray process for each application.
