Tungsten carbide – 12% cobalt
55588C is a spherical powder manufactured by agglomerating and sintering a formulation of 88% tungsten carbide with 12 % 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. 55588C powder is also suitable for other HVOF systems or plasma spraying. 55588C sprayed coatings are hard and dense with high bond strengths on a wide variety of metallic substrates. They resist exceptionally well to low stress
abrasion, fretting wear and hard particle erosion for service temperatures up to 500°C.
Applications
- Knife blades
- Oil and gas extraction parts
- Pump seals
- Capstans and pulleys
- Exhaust fan blades
- Extrusion dies
- Compressor rods
Technical data:
| Micro hardness | ~1200 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): ~ 54% |
| 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. |
