Characteristics of laser cladding
Laser cladding is the technology for wear resistant hardfacing of the future. A metallic powder or wire is molten in the laser beam and deposited onto a metal substate. The nozzle system can either be co-axial or lateral. The laser beam has two funtions, preheating the substrate and melting the metal powder or wire.This way a perfect metallurgical bond between substrate and deposit is assured.

Advantages of laser cladding

  • automatic CNC process
  • deposit thickness 0,3-2 mm/layer
  • high precision in the deposit layer: tolerances 0,1 mm
  • perfect metallurgical bonding, no risk for debonding
  • no porosity, high density of the deposit
  • no cracks
  • delution with the substrate: less than 1 %, so the optimal characteristics of the deposit are assured on the whole thickness
  • heat-affected zone (HAZ) reduced and virtually no deformation
  • a wide range of deposit metals

Applications for laser cladding

  • repair of worn out parts and tools
  • wear resistant hard facing
  • turbine parts
  • corrosion protection deposits based on steel, tool steel (M2, M4,…) , stainless steel 300, 400,..
  • cobalt based: stellite 1, 6, 12, 21, 25
  • nickel based: Hastelloy, NiCrBSi, Inconel 600, 625, 718,…
  • aluminium based: Al + 5 à 60% Si
  • copper based: Cu + 10% Al,…
  • carbides: tungsten carbides, titanium carbides, Ni Cr B Si,…
