The Lasercarb® licensed laser cladding technology developed by TECHOGENIA, France, restores worn working surfaces and provides such properties as wear resistance, heat resistance, resistance to corrosion and other aggressive environments.
- Low heat input
- Reduced area of the heat affected zone (HAZ)
- Base metal voltage drop
- Can be performed on a finished surface (i.e., repair work)
- CNC control
- It is possible to apply a carbide coating on a localized area (i.e. hardening of a certain area).
- No WC microstructure damage
- Low dilution (1%) compared to tungsten inert welding / plasma transferred arc welding (TIG / PTA) (about 10%): ensures high hardness with a thin coating layer (0.5 mm when using a laser compared to 4.5 mm for TIG / PTA)
- Excellent bonding = better impact resistance compared to high velocity oxygen fuel (HVOF) spraying
