It is shown that heating of an internal layer of microarc coating up to temperatures at which insignificant rates of heat removal from microdischarges that possess a temperature of no less than 1200 C are ensured leads to realization of a sufficient time interval for the occurrence of almost 100% transformation of low-temperature aluminum-oxide modifications into high-temperature ones. Insufficient heating of a number of areas of the coating to these temperatures is the main reason for formation of a composite microarc coating that contains both low- and high-temperature aluminum-oxide modifications in its internal layer. © 2013 Pleiades Publishing, Ltd.
