The amorphous ribbon produced from the 71KNSR alloy was studied by thermal analysis in initial state, after annealing. after milling. and as a coating separated from substrate. The coating was produced by plasma spraying of the powder obtained by milling of the ribbon. As compared to thermal-analysis curves of the initial ribbon. the curve of the coating exhibits the following features: the region of supercooled liquid is absent: the relationship between the intensities of the exothermic peaks of crystallization changes; the crystallization temperature decreases by 6 degrees C; and the enthalpy of the first stage of crystallization decreases from 89 to 81 mJ/mg.
