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


  • 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).

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
