INVESTIGATION OF STRUCTURE AND PROPERTIES OF THE CO58NI10FE5B16SI11 COATINGS PRODUCED BY PLASMA SPRAYING ONTO AN ALUMINUM SUBSTRATE

The amorphous ribbon produced from the 71KNSR alloy was studied by the rmal analysis in initial state, after annealing. after milling. and as a coating separated from substrate. The coating was produced by plasm a spraying of the powder obtained by milling of the ribbon. As compare d to thermal-analysis curves of the initial ribbon. the curve of the c oating exhibits the following features: the region of supercooled liqu id is absent: the relationship between the intensities of the exotherm ic peaks of crystallization changes; the crystallization temperature d ecreases by 6 degrees C; and the enthalpy of the first stage of crysta llization decreases from 89 to 81 mJ/mg.
