Abstract

"Laser deposition is an extension of the laser cladding process for rapid prototyping of fully dense metal components. This laser additive manufacturing technique allows quick fabrication of fully-dense metallic components directly from Computer Aided Design (CAD) solid models. The incoming powder is metallurgically bonded with the substrate upon solidification. The part is fabricated in a layer by layer manner in a shape that is dictated by the CAD solid model. The first part of the thesis uses simulation and experiments to investigate the effect of the process input parameters...In the second part, a heat transfer and fluid flow model for laser deposition is developed is used to predict dilution under varying process parameters"--Abstract, leaf iv.
