Lasercarb

Lasercarb®

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.

Technology advantages

Heating

  • Low heat input
  • Reduced area of the heat affected zone (HAZ)
  • Base metal voltage drop

Geometry

  • 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).

Metallurgical performance

  • 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
