SINGULARITIES OF THE CORROSION BEHAVIOR OF THE CONSTRUCTIONAL COPPER IN MELTS ON THE BASIS OF SODIUM METAPHOSPHATE
Interaction regularities in system copper – vitreous melts of NaPO <sub>3</sub> has been investigated. The influence of different cationic composition of melts on the corrosion rate of constructional copper has been found. Corrosion resistance growth is connected with phosphide Cu <sub>3</sub>P layer formation on the surface during treatment in metaphosphate melts at 750 – 800 °C
