Samenvatting

Laser powder deposition of thick metallic coatings is a surface engineering technique that provides coatings resistant against high loading impact, severe wear and corrosion at high temperatures. In this work Orientation Imaging Microscopy (OIM) based on Electron Back Scatter Diffraction in a Scanning Electron Microscope was employed as a very powerful instrument for the study of the relationship between processing parameters and the microstructure of individual and overlapping laser tracks at different processing speeds.

OIM provided new insights into the microstructure of laser clad coatings and very useful information concerning the directional grows of individual grains, the solidification texture and the shape of the solidification front during laser processing. Strong correlations between the microstructure, processing parameters as well as mechanical performance were found.
