The authors study the features of oxidation and determine the temperature limits in the application of carbon steels with composite electrochemical coatings based on the Ni-B system. Coatings based on the Ni-B system deposited on carbon steels can operate for a long time at temperatures up to 750 degrees C. Above this temperature, they begin to decompose and oxidize strongly owing to the instability of nickel borides. A reliable functioning of a composite coating of the composition is possible in the absence of unreacted boron in it.
