Table I gives a broad comparison of coating processes. The data shown are based on typical applications and parameters. There can be exceptions to these data, dependent on the specific applications and parameters, Metallisation will be happy to offer advice for specific applications.
The oil and gas industry commonly use laser cladding for many of its processes including oil refinery process plants, valve balls/seats, down hole stabilizers, sand valves and hydraulic rods. The steel industry would typically use laser cladding in process rolls, high temperature process rolls, coal and ore crushing hammers and wear plates. Various other industry sectors, such as automotive and power generation, will also have applications for laser cladding. The coating materials are just as diverse as the applications and include, Cobalt 6, WC/Ni, NiCrMo and FeCrB.
LASE Ltd. was established by Sam Lester, who has extensive experience in laser cladding, and his brother Ben, who is a qualified CNC Programmer. Sam, Technical Director at LASE says:
The MET-CLAD system is the result of a lot of work between us and Metallisation. I am delighted with the system, which is very easy to use and incredibly flexible. Traditionally, laser systems have been cumbersome and technically complex, which limited the uptake of laser cladding in industry. Now, thanks to the input of both LASE and Metallisation, we have a system that is robust, simple to use, incredibly effective (Figure 2).
