Increases the service life of stressed
components through maximum wear protection.

Characterised by uniform layer thickness distribution, low coefficient of friction against metals (steel), good resistance to sliding wear and excellent resistance to abrasive wear. The coating also has good corrosion resistance. Corrosion and wear protection properties can be further improved by applying an electroplated or chemically deposited undercoating.
