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 ...

Laser powder technology for cladding and welding
Journal of Thermal Spray Technology, 1999Laser powder technology offers several advantages compared to conventional cladding and welding techniques and is attracting increasing industrial interest. The laser materials processing group of the German Aerospace Center at Stuttgart, Germany, is currently developing these new methods for application in industrial process engineering.

Effect of laser power on clad metal in laser-TIG combined metal cladding
SPIE Proceedings, 2003TIG arc welding has been used to date as a method for clad welding of white metal as bearing material. We propose a new clad welding process that combines a CO 2 laser and a TIG arc, as a method for cladding at high speed. We hypothesized that this method would permit appropriate control of the melted quantity of base metal by varying the laser power.

Triple-Clad Fibers for Lasers and Amplifiers
CLEO/Europe Conference on Lasers and Electro-Optics, 1998A novel design of the refractive index profile for cladding-pumped fiber lasers and amplifiers has been developed and experimentally realized (cf. Fig. 1). The core (1) consists of pure silica and is doped with rare earth ions only. The light guiding in the core is provided by a depressed-index cladding (2) which is thick enough to suppress energy ...

A simple but realistic model for laser cladding
Metallurgical and Materials Transactions B, 1994A model which takes into account the main phenomena occurring during the laser-cladding process is proposed. For a given laser power, beam radius, powder jet geometry, and clad height, this model evaluates two other processing parameters, namely, the laser-beam velocity and the powder feed rate.

Scanning optics is an effective way to manipulate a laser beam for laser cladding. The numerical adjustment of the scanner gives a great deal of flexibility to the cladding process. However, the effect of the scanned beam on the cladding process itself has not been studied very thoroughly so far.
