Показано, что сталь, имеющая более сильный наклеп, проявляет более высокую износостойкость, чем менее упрочненная сталь. Этот факт представлен как следствие реализации более низкой амплитуды напряжения цикла в условиях малоцикловой усталости материала, прилегающего к пятнам фактического контакта более упрочненной стали. Отмечено, что характеристики контакта стали Ст3 несколько выше известных характеристик контакта закаленных сталей. Это обусловлено более высоким запасом пластичности поверхностного слоя стали Ст3 по сравнению с запасом пластичности поверхностного слоя закаленных сталей. Структурные изменения поверхности трения наблюдаются в виде образования слоя вторичных структур, которые содержат кристаллические фазы: FeO, α-Fe и γ-Fe. Представлено оптическое изображение изношенной поверхности, имеющей признаки появления жидкой фазы. Эта фаза является не результатом плавления, а результатом появления сильновозбужденных атомов в тонком поверхностном слое.</p></abstract><trans-abstract xml:lang="en"><p>The current dependences of wear intensity and specific surface electric conductance of sliding electric contact 0,2 % C steel/0,45 % C steel are represented at contact current density higher than 100 A/cm2 without lubricant. It was shown that the steel having stronger cold work hardening realized has higher wear resistant than the low hardening steel. This fact is represented as a result of the realization of lower cycle stress amplitude in conditions of low cycled fatigue of the material adjoining to real contact spots of stronger hardened steel. It was marked that the contact characteristics of 0,2 % C steel are some higher than known contact characteristics of quenched steels. This is caused by higher plasticity reserve of 0,2 % C steel surface layer comparing with that of quenched steels. Structure changes of sliding surface were observed as a formation of friction induced structure layer containing crystal phases namely oxide FeO, α-Fe and γ-Fe. The optical image of worn surface having the signs of liquid phase appearance is shown. This phase is not a result of melting but it is a result of strong excited atoms appearance in thin surface layer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пластичность поверхностного слоя</kwd><kwd>усталостное разрушение</kwd><kwd>пятна фактического контакта</kwd><kwd>трение</kwd><kwd>интенсивность изнашивания</kwd><kwd>электропроводность скользящего контакта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surface layer plasticity</kwd><kwd>fatigue deterioration</kwd><kwd>real contact spots</kwd><kwd>friction</kwd><kwd>wear intensity</kwd><kwd>electric conductance of sliding contact</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ</funding-statement><funding-statement xml:lang="en">RFFI</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Федорченко И.М., Пугина Л.И.
