|
This coating can be used in a wide range of applications. These include steel mill rolls, forging tools, exhaust fans, pumps and other components subject to wear. |
| Nickel 46% Chromium 11% Tungsten carbide/nickel, 35%Iron, silicon, boron, carbon |
- Macrohardness - Rc 58 - 60
- Microhardness - KHN50 950
Surface Texture
- as fused - 2-4 microns
- as ground - 0.3 - 0.5 microns
|
This coating can be used where wear resistance is severe. It can be used on pump components, rolls, shafts, exhaust fans and other components subject to severe wear. |
| Cobalt 40% Nickel 27% Chromium 18% Molybdenun 6% Silicon, boron and iron |
Surface Texture
- as fused - 6 - 7.5 microns
- as ground - 0.35 microns
|
This coating is useful where cobalt base wear coatings are required and the substrate is a low shrink material. The possible applications are similiar to the other fused coatings. |

Typical Applications |
| Nickel 75% Graphite 25% |
- Macrohardness - R15y 30 - 50
Surface Texture
- as sprayed - 25 - 33 micron
|
This coating is used in compressors on jet engines or in other machinery requiring close tolerance clearances in seal areas. It can be used as a low friction coating in the glass industry. |
| Aluminium61%, Graphite23%, Silicon 8% |
- Macrohardness - R15y 50 - 70
Surface Texture
- as sprayed - 10 - 13 microns
- as machined - 4 - 6 microns
|
This coating is a lower cost alternative to the coating above. It is generally more erosion resistant at elevated temperatur and is used in similiar areas. |
