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.
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).
