Abstract
A Co – Cr –Mo laser cladding applied on railway wheels is characterised by a combination of EBSD and EDX. A complete pass of the cladding is investigated to achieve a better understanding of the microstructure evolution during laser cladding. A microstructure with columnar grains extending over the whole thickness of the cladding is observed. The grains have a <001>-fibre texture with the fibre axis parallel to the normal of the substrate surface, and a substructure consisting of cells/dendrites. During the cladding process, two different kinds of precipitates form in the cell walls, which can be identified as M6C and a non-equilibrium phase. Furthermore, stacking faults are observed to occur in the cladding grains and are discussed with respect to the laser cladding process.

The authors are grateful to Simon Niederhauser for providing the clad samples. Thanks are also going to Henrik Svensson (Applied Physics Department, Chalmers University of Technology, Gothenburg, Sweden) for preparing the TEM sample by the focussed ion beam technique. Furthermore, the authors acknowledge the assistance of Romeo Saliwan Neumann during EBSD measurements at BAM, and the help of Austin Day (HKL Technology Inc.) and René de Kloe (EDAX BV) when indexing the EBSD pattern of the non-equilibrium phase.
