Cladding-pumped bismuth-doped fiber laser
Optics Letters, 2022For the first time, to the best of the authors’ knowledge, a cladding-pumped bismuth-doped fiber laser (BDFL) is demonstrated. A “home-made” Bi-doped germanosilicate fiber with a 125 µm circular outer cladding made of fused silica and coated by a low refractive index polymer is used as an active medium pumped by commercial multimode laser diodes with a

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.

Directionally Solidified Laser Cladding
Advanced Materials Research, 2012To repair a directionally solidified aero blade, laser cladding on GH710 substrate using stainless steel powder and Ni-based alloy powder by Nd:YAG laser was carried out. The condition of achieving directional solidification in the open and normal temperature environment was researched.

Laser Cladding: Fatigue Properties
2020Laser cladding is one of the most investigated additive manufacturing technologies for the production of metallic or metal matrix composite components. High-energy laser beams are employed to melt powders onto a substrate to form 3D components layer by layer. In comparison with other manufacturing or repairing technologies, laser cladding offers a wide

Powder laser cladding made using multichannel laser
Strengthening Technologies and Coatings, 2023The results of experimental studies on the formation of the structure and properties of laser cladding using a multichannel (48 beams) CO2 laser are presented. The advantages of using a multichannel laser for deposition of deposited coatings on structural steel are shown.

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.

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.

Geometry Modelling of Clads Generated by Laser Cladding
Materials Science Forum, 2012The laser cladding process is based on the generation of a melt-pool in a substrate where a filler material is injected, generating a high quality clad with a minimum heat affected zone. This process is industrially used to generate coatings over wear or damaged surfaces, being an alternative to traditional deposition techniques.

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 ...
