Study of the real structure of laser-cladded steel

Popis výsledku v původním jazyce

Hot-work tool steels are common die materials used in metal and casting industries. Dies, moulds, and more suffer damage due to wear and thermo-dynamic stresses during their lifetime. Therefore, various methods have been developed for their refurbishment or repair, which is cheaper than manufacturing new ones. A great benefit of laser cladding (one of the methods of additive manufacturing) is the high 3D production rate that is minimally influenced by thermal stresses due to a low heat input on surrounding material. Real structure is one of the most important factors that influences the behaviour of the product, especially fatigue life. Therefore, the aim of this thesis is to describe the effects of the laser cladding process on the real structure, microstructure, and mechanical properties of H13 tool steel using various diffraction methods. The results obtained were compared with the local hardness and wear measurements. Laser cladding of H13 tool steel showed great application potential. At the end of the work, further research is proposed that will necessarily focus on the design of the printing layout when cladding a larger volume.
