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 3 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 3P layer formation on the surface during treatment in metaphosphate melts at 750 – 800 °C
