Abstract—Copper-based coatings on iron and nickel substrates are prepared from separated glass–copper
composites. The coatings are formed at temperatures of 1080–1100°C, which provides the formation of metal
melts. It is revealed that, after separating the glass–metal composite, the formation of a metal layer obeys gen-
eral regularities of the interaction in the “solid metal–thin melt layer” system. The coating structure is governed
by the phase diagram of the “substrate–coating” metal system.
