Показано, что в гомогенной паре трения полиоксиметилен-полиоксиметилен износ экспоненциально возрастает при увеличении контактного давления и скорости скольжения. В гетерогенной паре трения полиэфирэфиркетон-полиоксиметилен изнашивание полиоксиметилена существенно ниже и мало зависит от скорости скольжения и давления на контакте. Методом масс-спектрометрии показано, что в паре трения полиэфирэфиркетон-полиоксиметилен образование продуктов трибодеструкции макромолекул не наблюдается, в отличие от термодинамически совместимой пары полиоксиметилен-полиоксиметилен. В паре полиоксиметилен-полиоксиметилен продукты трибодеструкции полиоксиметилена регистрируются, причём кинетика их образования прямо коррелирует с ростом силы трения уже при мощности трения на уровне 10–2 МПа·м/c. Различия в износе проинтерпретированы как следствие взаимопроникновения макромолекул через границу раздела пары полиоксиметилен-полиоксиметилен и их разрывов в поле сдвига. Термоактивированное взаимопроникновение макромолекул визуализировано методом молекулярной динамики. Разработанный подход и получаемые им результаты будут полезны для детального исследования молекулярных механизмов трения и изнашивания практически используемых полимеров и их композитов.</p></abstract><trans-abstract xml:lang="en"><p>Friction and wear of polyoxymethylene upon friction against polyoxymethylene and polyetheretherketone have been analyzed. It is shown that wear exponentially increases upon growth of contact pressure and sliding velocity in the homogeneous friction pair polyoxymethylene-polyoxymethylene. In the heterogeneous pair polyetheretherketone-polyoxymethylene the wear of POM is small and exhibits no registered dependence on sliding velocity and contact pressure. Mass-spectrometric analysis shows that the macromolecular decomposition products are not detected for polyetheretherketone-polyoxymethylene pair. However, for thermodynamically compatible polyoxymethylene-polyoxymethylene pair their formation, accompanied by the growth of friction force, is detected at the levels of friction power as low as 10–2 MPa·m/s. These differences have been interpreted to result from interpenetration of polyoxymethylene macromolecules and their rupture in the shear field at the homogeneous polyoxymethylene-polyoxymethylene friction interface, absent in polyetheretherketone-polyoxymethylene pair. Thermally activated interpenetration of macromolecules for polyoxymethylene-polyoxymethylene pair and its absence in polyetheretherketone-polyoxy­methylene pair has been visualized by means of molecular dynamics calculations. The experimental approach and the results of its application will be useful in detailed studies of molecular level friction mechanisms of friction and wear of industrially used polymers and their composites.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полимер</kwd><kwd>пара трения</kwd><kwd>сила трения</kwd><kwd>износостойкость</kwd><kwd>вакуум</kwd><kwd>масс-спектрометрия</kwd><kwd>пластические деформации</kwd><kwd>температура в зоне трения</kwd><kwd>полиоксиметилен</kwd><kwd>полиэфирэфиркетон</kwd><kwd>температура стеклования</kwd><kwd>молекулярная динамика</kwd><kwd>термодинамическая совместимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polymer</kwd><kwd>friction pair</kwd><kwd>friction force</kwd><kwd>wear resistance</kwd><kwd>vacuum</kwd><kwd>mass-spectrometry</kwd><kwd>plastic deformations</kwd><kwd>temperature in friction zone</kwd><kwd>polyoxymethylene</kwd><kwd>polyetheretherketone</kwd><kwd>glass transition temperature</kwd><kwd>molecular dynamics</kwd><kwd>thermodynamic compatibility</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Мышкин Н.К., Петроковец М.И.
