WC-12Co Thermal Spray Powder
- Sintered and crushed powders are irregular.
- The maximum service temperature is up to 500℃.
- The dense coating has high hardness with excellent resistance to abrasive wear, fretting wear, adhesive wear, and erosion wear.
- High fracture toughness.
- Mainly used in mechanical parts, oil and gas equipment, metallurgical roller and pump seal, etc.
