BORDEM® EVODUR
Increases the service life of stressed components through maximum wear and corrosion protection.
Characterised by uniform layer thickness distribution, good resistance to abrasive wear and high resistance to cavitation and erosion wear. The coating also has good corrosion resistance, shows solid friction properties with many material pairings and is RoHS compliant. Corrosion and wear protection properties can be further improved by applying an electroplated or chemically deposited undercoating.
