Chromium carbide – 20% nickel chromium
55580C is a spherical powder manufactured by agglomerating and sintering a formulation of 80% chromium carbide with 20% nickel-chromium matrix by weight. It has been developed for spraying with the CastoJet CJK5 system which is a High Pressure HVOF
using kerosene as liquid fuel. 55580C powder is also suitable for other HVOF systems or plasma spraying. 55580C sprayed coatings are hard with high bond strengths on a wide variety of metallic substrates. They resist exceptionally well to high temperature
abrasion, oxidation and solid particle erosion for service temperatures up to 870°C.
Applications
- Hydraulic cylinders and piston rods
- Boiler coatings
- Pump seals
- Cam shaft
- Furnace rolls
- Hard chrome plating replacement
Technical data:
| Micro hardness | ~ 1150 HV0.5 |
| Service temperature | max 870°C (1600°F) |
| Bond strength (EN 582 | 1994): >70 MPa (>10,000 psi) |
| Deposition efficiency (EN ISO 17836 | 2004): ~ 42% |
| Porosity (image analysis) | <1% |
| The above values depend on the spraying system | |
| and parameters used. Therefore measured coating | |
| properties may vary from above values. |
