This project deals with the simulation and experimental validation of eigenstresses in laser- generated composite materials. These materials are used as wear-resistant coatings protecting metallic surfaces against abrasion, erosion or corrosion. Laser dispersion is the primary process used in this project, where working surfaces of already manufactured parts are coated by adding tungsten carbide powder into the melt pool of a base material. The coating extends the part's lifetime due to the outstanding material characteristics of the locally produced metal matrix composite (MMC). Eigenstresses, which are the residual stresses left in the MMC material after the coating process, shall be investigated and predicted within the framework of this project.
