Cemented Carbide Coatings by Plasma Spray
Cemented carbide already excels in wear resistance, strength and hardness. Spraying WC-Co powder by plasma takes those properties onto workpieces that cannot be made from solid carbide - at a fraction of the cost.
Key Properties
- Hardness HRC 85-92 against severe abrasion
- Strong oxidation resistance at high temperature
- Low friction coefficient with special formulations - less energy loss
- Dense, uniform deposition under automated control
Typical Applications
- Machinery parts and conductive/stable surfaces
- Mould protection in aggressive environments
- Tools requiring wear and oxidation protection
- Aerospace components in high-temperature service
Example Configuration
- Spray materials: WC-Co alloy powder
- Spray area: 400 x 400 mm
- Coating thickness: 0.3-0.6 mm
- Cooling: water circulation
- Control: digital PLC with full safety interlocks
Workflow
Surface cleaning and grit blasting, powder loading and drying, vacuum start-up, parameter-controlled spraying, monitored cooling and non-destructive acceptance testing before delivery.
