Abstract: The feasibility of the fabrication of coatings for elevated-temperature structural applications by laser cladding MoSi₂ powder on steel was investigated. A dense and crack-free fine coating, well-bonded with the substrate has been obtained by this technique. This coating consists of FeMoSi, Fe₂Si and a small amount of Mo₅Si₃ due to dilution of the substrate in the coating. The microstructure of the coating is characterized of typical fine dendrites. The dendrites are composed of FeMoSi primary phase, and the interdendritic areas are two eutectic phases of FeMoSi and Fe₂Si. The hardness of the coating reaches 845 Hv_0.5, 3.7 times larger than that of the steel substrate (180 Hv_0.5).
