Выбран оптимальный режим обработки, для которого характерно образование термически стабильного слоя с повышенной в 1,8 раза микротвердостью глубиной около 40 мкм; частичное растворение в упрочненном слое крупных включений графита и колоний эвтектики, по которым происходит разрушение детали; образование на поверхности припеченного слоя твердой смазки мелкодисперсного графита; создание дополнительного рельефа изнашиваемой поверхности, облегчающее приработку сопрягаемых поверхностей.</p></abstract><trans-abstract xml:lang="en"><p>The analysis of the structure and microhardness of a part made of heat- and acid-resistant cast iron of the TEA brand after electric blasting of the internal cylindrical surface is carried out. The optimal processing mode is selected, which is characterized by the formation of a thermally stable layer with a 1.8-fold increased microhardness depth of about 40 microns; partial dissolution in the hardened layer of large graphite inclusions and eutectic colonies, which cause the destruction of the part; the formation of a fine graphite on the surface of a baked layer of solid lubricant; creating an additional relief of the wear surface, which facilitates the running-in of the mating surfaces.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>чугун с вермикулярным графитом</kwd><kwd>фреттинг-коррозия</kwd><kwd>электровзрывное легирование</kwd><kwd>микроструктура</kwd><kwd>микротвердость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cast iron</kwd><kwd>electric explosive alloying</kwd><kwd>microstructure</kwd><kwd>tempering</kwd><kwd>microhardness</kwd><kwd>metallographic studies</kwd><kwd>fretting corrosion</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">Reboul M.C., Baroux B.
