Анотація

В рамках теорiї фазових переходiв Ландау з використанням модуляцiї густини i надлишкового об’єму в ролi параметрiв порядку описано фазовий перехiд другого роду мiж структурними станами межового мастила, затиснутого мiж атомарно-гладкими твердими поверхнями. Знайдено зв’язок мiж таким чином визначеними параметрами порядку. Дослiджено стацiонарнi стани мастильного матерiалу в залежностi вiд керуючих параметрiв – температури мастила, пружної деформацiї в змащувальному шарi i зовнiшнього навантаження на поверхнi тертя. Проведено моделювання кiнетики плавлення в рамках механiчного аналога трибологiчної системи iз пружнiстю.
