Abstract

High speed steel laser cladding coatings are complex because cracks appear and the hardness is lower than expected. In this paper AISI M2 tool steel coatings on medium carbon AISI 1045 steel substrate have been manufactured and after Laser Cladding (LC) processing it has been applied a tempering heat treatment to reduce the amount of retained austenite and to precipitate secondary carbides. The study of metallurgical transformations by Scanning Electron Microscopy (SEM) and Electron Back Scattered Diffraction (EBSD) shows that the microstructure is extremely fine and complex, with eutectic transformations and MC, M₂C and M₆C precipitation. Therefore, after the laser coating is necessary to use post-weld heat treatments.
