Hardfacing Cladding
Hard facing is a collective term for techniques in which a wear-resistant or corrosion-resistant layer is applied to a component by welding or fusion.
Plasmajet specializes in a wide range of hardfacing techniques, tailored to specific wear profiles and load types. From simple build-ups to advanced combinations with carbide inserts or synthetic diamonds.
How does Hard Facing work?
Hardfacing involves building up a coating by applying metal powders, wire, or segments to a base material using heat (welding or melting). This layer is usually harder and more wear- and corrosion-resistant than the original surface.
- The substrate can be sandblasted beforehand to improve adhesion.
- The coating is formed by melting or brazing.
- After cooling, post-treatment may follow (grinding, milling)
For more complex applications, carbide particles are embedded in the coating, or even Widia segments and synthetic diamonds are attached to the surface using silver brazing, with additional protection of the surrounding areas against erosion.
Spray & Fuse
Spraying on coating, then thermally fused to form a wear-resistant layer.
PTA (Plasma Transferred Arc)
Precision brazing with high melting temperatures, ideal adhesion.
Laser cladding
Contactless welding with powder and laser, minimal heat input.
Conventional welding (MIG/MAG, TIG, MMA)
Classic welding for structural construction or repair.
Coatings can be customized based on desired properties:
- Abrasion resistance
- Corrosion protection
- Thermal insulation
- Electrical insulation or conduction
