Laser beam build-up welding (cladding) is becoming increasingly established in automotive production, in the aerospace industry, as well as in mould and tool technology. Impulses for this development are the availability of the high power diodes, user-friendly systems, and new hybrid techniques for increased productivity and efficiency.

Laser cladding is a hardfacing process that uses a high-powered laser beam to melt the coating material and a thin layer of the substrate to form a pore- and crack-free coating 50 μm–2 mm thick with low dilution that is perfectly bonded to the substrate.

Effect of laser beam incidence angle on cladding morphology in laser cladding process
Journal of Mechanical Science and Technology, 2020The change of angle θ between laser cladding powder plane and substrate plane will lead to changes in cladding layer's geometric morphology. Therefore, we established a quantitative numerical prediction model for cladding layer geometry. In this model, we consider the variation of θ, the laser energy attenuation rate and the temperature rise of the ...

Laser cladding is used in the repair of high value industrial components such as rollers, axles and turbine blades. The absence of defects is essential to the remanufacturing process. Consequently, a non-intrusive cladding monitor that is robust in detecting defects and minimizes false positives is very desirable.

Nickel and titanium aluminides already show a high potential for use in lightweight applications at elevated temperatures; however, the strength of these intermetallics can be increased by directional solidification. These materials show a brittle behaviour at temperatures less than 600°C.

The Depositional Laser Cladding with Fiber Laser
Materials Science Forum, 2009Laser cladding has been developed as a useful technology to modify material surface in industry. In this paper a new approach of surface modification is introduced. Depositional Laser Cladding (DLC) was developed and the different mechanisms were investigated during the manufacture.

Laser cladding of bioactive glass coatings
Acta Biomaterialia, 2010Laser cladding by powder injection has been used to produce bioactive glass coatings on titanium alloy (Ti6Al4V) substrates. Bioactive glass compositions alternative to 45S5 Bioglass were demonstrated to exhibit a gradual wetting angle-temperature evolution and therefore a more homogeneous deposition of the coating over the substrate was achieved ...
