Experiments on dry high-speed cutting of a cutting plate with a high-entropy ion-plasma coating based on (AlCrZrTiTa)N with a thickness of about 3.0 μm have been carried out (It was performed during the 130 m run-in phase and after cutting for 260 m). It is shown that tribological adaptation of the coating from high-entropy nitride with amorphous-nanocrystalline structure under conditions of high-speed dry cutting is a nonequilibriumprocess and includes partial oxidation of nitride fragments and dynamic competitive formation of protective films of triboxides with thermal barrier and antifriction properties from the very initial stages of cutting.

Проведены эксперименты по сухому высокоскоростному резанию режущей пластины с высокоэнтропийным ионно-плазменным покрытием на основе (AlCrZrTiTa)N толщиной порядка 3,0 мкм (на стадии приработки длительностью 130 м и после резания в течение 260 м). Показано, что трибологическая адаптация покрытия из высокоэнтропийного нитрида с аморфно-нанокристаллической структурой в условиях высокоскоростного сухого резания является неравновесным процессом и включает в себя частичное окисление фрагментов нитрида и динамическое конкурентное образование защитных пленок трибооксидов с термобарьерными и антифрикционными свойствами с самых начальных стадий резания.
