Abstract

Inventia se refera la o baie de saruri topite pentru nitrurarea materialelor din fier, care contine 25..45% cianati si în mod suplimentar 0,5...100 ppm seleniu sub forma de compusi de seleniu si /sau ca seleniu elemntar. Baile saline pentru piese dinotel si fier, care sînt compuse din cianat alcalin si carbonat alcalin, produc în unele cazuri, pe suprafata pieselor depozite care pot duce la deranjamente la utilizarea acestor piese.O calitate impecabila a suprafetei se realizeaza în bai saline denitrurare, care mai contin si 0,5...100 ppm seleniu.
