Conclusions During plasma-spraying a multiphase structure composed of an amorphous matrix and crystalline Ni, Ni2B, and Ni3B phases forms in an Ni3B alloy. In the range 360–530° K the amorphous matrix experiences structural relaxation, which is responsible for a nonmonotonic character of the temperature dependence of the electrical resistivity and elongation of coatings. The amorphous phase crystallizes in the region of 570°K. The decomposition of the amorphous structure leads to a fall in electrical resistivity and to the appearance of a volume effect. Phase transitions in the range of postcrystallization temperatures for the amorphous structure have a less marked effect on the ρ = f (T) and ΔZ/Z300°K = f(T) relationships.
