Our Surface Coatings Range
There are four types of standard range Hardide coatings all of which can coat internal surfaces.
Bespoke coatings can be produced for specific applications.
| Type | Hardness | Toughness | Thickness | Applications |
| Hardide-T (Tough) |
1100 - 1600 Hv | Excellent | Typically 50 μm | Oil tools, pumps, valves, actuators |
| Hardide-A | 800 - 1200 Hv | Excellent | Typically 50-100 μm | Developed as a Hard Chrome replacement, primarily for aerospace applications |
| Hardide-M (Multi-Layer) |
1200 - 2000 Hv | Good | Typically 50 μm | Abrasion/erosion resistance |
| Hardide-H (Ultra-Hard) |
3000 - 3500 Hv | Satisfactory | 5-12 μm | Self-sharpening blades |
