| Tungsten Carbide / Cobalt (83/17) | Macrohardness - Rc 50-55
Microhardness - DPH300 750-950 Tensile Bond Strength - 62MPa(9000psi) Surface Texture: - as sprayed - 6 - 9 microns - as ground - 0.25 - 0.5 microns |
Used in low temperature environments below 500°C on parts subject to fretting and abrasive wear. Many aero engine applications including brackets and mounts. Industrial applications include pump shafts, piston and wire drawing capstans. |
| Chrome Oxide | Macrohardness - Rc 70-72 Microhardness - DPH300 900-1300 Tensile Bond Strength - 41MPa(6000psi) Surface Texture: - as sprayed - 6 - 7.5 microns - as ground - 0.4 - 0.5 microns |
Used extensively in high wear areas on pump seals, impellers and sleeves where resistance to corrosion by acids, alkalis and alcohols is important. Also used in the textile and paper industries on parts subject to wear by thread or paper products. |
| Yttria stabilised Zirconia | Macrohardness - Rc 30-35 Surface Texture: - as sprayed - 9 - 12 microns |
Used as a thermal barrier coating where resistance to high temperature corrosion and thermal shock is important. Components coated with this material include gas turbine parts, cylinder liners, exhaust ports and other engine parts subject to temperatures above 850°C. |
