High wear protection combined with good corrosion resistance makes BALINIT® CROVEGA a much sought-after solution for smooth surfaces. Coating adhesion and hardness are higher than with hard chromium plating, while oxidation resistance is unchanged.
Foodstuff-neutral CROVEGA is extra dense and smooth, and therefore ideal for plastics injection moulds and other highly polished moulds.
| BALINIT CROVEGA | |
|---|---|
| Coating material | CrN |
| Coating technology | Sputter |
| Coating colour | silver-grey |
| Coating hardness HIT [GPa]* | 18+/-3 |
| Coefficient of friction (dry) vs. steel** | ~0.5 |
| Max. service temp. [°C]**** | 700 |
| Process temperature [°C] | < 250 |
| General remark | All given data are approximate values, they depend on application, environment and test condition. |
| *Coating hardness HIT [GPa] | Measured by nano indentation according to ISO 14577. For multilayers the hardness of the different layers varies. Hardness can be adapted to the application. |
| **Coefficient of friction (dry) vs. steel | Determined by ball-on-disc test in dry condition with an Steel ball according to ASTM G99. During run-in the given values may be exceeded. |
| ****Max. service temp. [°C] | These are approximate values out of the field. Due to thermodynamic laws there is a dependency of pressure in application. |
