The goal of this work was to provide data for a study of correlation between the laser cladding parameters and the microstructure of Co-based coatings. Samples were made from laser clad coatings and single laser tracks on a 42CrMo4 steel bar with Eutroloy16012 powder. These samples were cut longitudinally and transversally to the cladding direction. After that Orientation Imaging Microscopy scans of the samples were made at different parts of the laser track. A total of 42 Orientation Imaging Microscopy pictures were made in providing this data. A new experimental set-up and coating sample cut was introduced for the study of the microstructure in different positions inside laser tracks. It is found that the Vickers hardness of the dept and the heat-affected zone of a single laser track depends on the laser cladding speed. The hardness of the coating also correlates with the cladding speed due to the presence of the new and more pronounced interfaces at higher cladding speeds.
