Laser cladding with metallic powders
… discussed. Using these models, useful tools for cladding operators and engineers are proposed. The energetic balance of the process is presented. Energetic redistribution in laser cladding process is analysed in detail, and quantification of process efficiency and energy losses is given. The …

A Thermal and Mechanical Model of Laser Cladding
… Simulation results were obtained for a system (cladding of C95600 copper on AA333 aluminum alloy) in which experiments had been successfully carried out. A simple model of dilution, i.e. the change in local composition due to mixing, is included. In 3D stress analysis, numerical convergence is …

Oxidation behavior of laser clad nickel-aluminum-chromium-hafnium alloys
… alloys containing reactive elements remains. Laser cladding is the process where a mechanical mixture of powders is rapidly melted and fused to a solid substrate using a CO$\sb2$ laser. The effects of laser cladding upon scale retention on NiAlCrHf alloys after cyclic and isothermal exposure …

Einsatz der CMB-Technologie zur Herstellung von Hinterschneidungen bei metallischen Bauteilen
… generation of metal parts and tools. It combines laser cladding and high speed milling in one machine tool. Based on the principal of laser cladding, in general, it is impossible to create undercuts, i.e. for conformal cooling channels. As a first step of the study, a material to build up …

Development and validation of a fatigue-resistant cladding technology
… the applied joining process. A fatigue-resistant cladding technology is presented in this thesis, with the aim of inducing compressive residual stresses in the clad layer. Through the generation of these beneficial compressive residual stresses an improvement in fatigue performance can be achieved …
