WC/C
Antifriction
The very low friction coefficient of WC/C makes this layer an excellent solution to prevent adhesive phenomena such as seizure and cold welding. It is applied to all sliding parts and moving parts where conditions of poor lubrication exist. WC/C is biocompatible and suitable for food contact.
Main characteristics
Very low coefficient of friction, good chemical inertia, good hardness, biocompatibility, food contact
Main benefits
Smoothness, particularly indicated on gears
Resistance to chemical aggression
