Tungsten carbide – 17% cobalt
55583C is a spherical powder manufactured by agglomerating and sintering a formulation of 83% tungsten carbide with 17% cobalt by weight. It has been developed for spraying with the CastoJet CJK5 system which is a High Pressure HVOF using kerosene as liquid
fuel. 55583C powder is also suitable for other HVOF systems or plasma spraying. 55583C sprayed coatings are hard and dense with high bond strengths on a wide variety of metallic substrates. They are tougher with a better fretting and impact resistance than WC-12Co coatings. They resist exceptionally well to low stress abrasion, fretting wear and hard particle erosion for service temperatures up to 500°C.
Applications
- Compressor shaft
- Down hole oil and gas extraction parts
- Pump seals
- Hydraulic cylinders
- Induced draft fan blades
- Pulverizer
- Mixer blades
- Hard chrome plating replacement
Technical data:
| Micro hardness | ~1230 HV0.3 |
| Service temperature | max 500°C (930°F) |
| Bond strength (EN 582 | 1994): >70 MPa (>10,000 psi) |
| Deposition efficiency (EN ISO 17836 | 2004): ~47% |
| Porosity (image analysis) | <0.5% |
| The above values depend on the spraying system | |
| and parameters used. Therefore measured coating | |
| properties may vary from above values. |
