Four Ni-Al-based and two Ni-Si-Ti-based intermetallic compounds were spray-deposited using a nitrogen gas for atomization. The impurity contents, relative densities and microstructures of the alloys were investigated in the as-deposited condition. The oxygen content of the alloys varied from 20 to 90 ppm, and the nitrogen content ranged from 10 ppm in a binary Ni 3 AI compound to 90 ppm in Ni-Al-Cr-Fe alloy and to 150 ppm in the case of Ni-Si-Ti. No sign of nitrides or oxides was observed. The relative density of the alloys was higher than 99% and the majority of pores located at grain boundaries. The chromium free Ni-AI alloy had a single-phase, equiaxed and recrystallized structure (γ'), while the chromium containing Ni-Al alloys had a γ/γ' multiphase structure with 5 - 20% volume fraction of the disordered γ phase. The γ phase formed a network or a bimodal mixture of network and lamellar structures in the ordered γ' matrix. The Ni-Si-Ti alloys showed a cell structure with cell interiors consisting of γ/γ' network structure and cell borders of the ordered γ' phase. The mechanical properties were comparable with those of the previously spray-deposited Ni 3 Al-based alloys or with those of the Ni-Si-Ti based alloys of the present type.
