Abstract

In this chapter the suitability of laser cladding (LC) process of exothermic powders, traditionally used in the self-propagating high-temperature synthesis (SHS) technology, is described. On site, the synthesis of new intermetallic phases and the overlapping of SHS and LC processes makes it possible both to obtain more durable parts of complex shape and to enlarge the functional resource of these coatings. The numerical simulation of thermal fields in the powder mixtures (Ni-Al, Ti-Al, Fe-Al) during the SHS and LC processes is examined in the last paragraph of this chapter and based on the experimental description of the thermal fields in the exothermal reaction wave front.
