Classification of the different metallising processes

Laser cladding

Laser cladding (LC)

Laser cladding is a process used for applying an ultra-dense coating, metallurgically bound and almost perfectly pure.

The process is used for improving resistance to wear, to corrosion and to impact.

The process uses a high power laser accurately directed so as to create a welding bath where a metal powder is applied. The powder is brought by a protective inert gas and blown along the same axis as the laser beam. The specific nature of the laser is used to produce very dense coats, with a minimum of losses (< 5%) and yet with very good metallurgical adhesion.

Materials used:

  • Cobalt6;
  • NiCrMo;
  • FeCrB.

Fields of application:

  • high-temperature rolling blocks, resistance to corrosion and hardness, valves (Cobalt 6);
  • valve balls/seats, rolling blocks, parts for boilers used in waste incineration, oil refineries (NiCrMo);
  • coal and mineral pulverisers/wear plates/valves (WC/Ni);
  • valve balls/seats, boiler components, parts for boilers used in waste incineration, hydraulic bars, stabilisers (FeCrB).
