Friction Surfacing has significant advantages over competing processes. It introduces machine tool technology to surface engineering, making the process reliable and repeatable. It is also a solid phase process that metallurgically bonds the coating to the substrate without the problems of porosity, slag inclusions or dilution experienced with traditional welding processes.

Inherent benefits of the Friction Surfacing process:

• Excellent bonding with no inclusions, porosity or oxidation
   
• Coating material properties improved
   
• Dense, clean & fine microstructures
   
• ‘Non-weldable’ (super) alloys can be deposited
   
• No melting of materials
   
• Negligible dilution
   
• Small localised HAZ (heat affected zone)
   
• No cracking in the HAZ
   
• Automatic & highly repeatable process
   
• Similar or dissimilar materials can be bonded
