Перспективным, по мнению авторов, является подход, при котором можно спрогнозировать параметры трещиностойкости зубчатых пар аналитически, исходя из позиций синергетики и самоорганизации к возникновению трещин в некотором поверхностном слое (ПС) зубчатого колеса. Для не приработанного зубчатого сопряжения состояние стойкости маловероятно. Для достижения равновесия, определяемого термодинамическим принципом максимума потока произведенной термодинамическим принципом максимума потока произведенной энтропии, в системе должно произойти согласование физико-механических свойств поверхностей трения с аналогичными характеристиками тел, которым принадлежат эти поверхности. В результате износа такое согласование вполне вероятно, особенно в аспекте геометрии микрорельефа поверхностей. По мере износа происходят изменения свойств поверхностей трения, при этом происходит изменение работы диссипации. Тогда, в соответсвии с принципом минимума работы диссипацивных сил, это изменение будет направлено на уменьшение работы диссипации до минимума. Следовательно вполне возможно достижение стойкого стационарного состояния трибосистемы.

On the other hand, the type of machining affects the cost of restoring and coating parts. Therefore, it is practically important to determine the effect of the method of machining and the surface finish of the base metal on the adhesion strength with electrolytic iron deposits.\u0000 Along with mechanical action, chemical processes play an important role in polishing. The surface of the metal is covered with thin, invisible oxide or salt films under the influence of the environment and the chemically active substances contained in the polishing pastes. When polishing, the film is removed, but on the exposed areas of the metal it is formed again. The hardness of abrasive grains during polishing is not as important as during grinding, since in the first case the abrasive removes a thin film that is less durable than metal.\u0000In the process of manufacturing parts by mechanical polishing, traces of processing in the form of small irregularities remain on their surface. The magnitude of these microroughness’s determines the surface finish of the parts. This characteristic has a great influence on the quality of the finish and the performance properties of the products. The smoother the metal surface, the better it resists corrosion.\u0000Improving the surface finish increases the wear resistance of the parts. Obtaining shiny surfaces is also associated with the need to remove microroughness.\u0000It has been determined that the cleanliness of the surface treatment of parts before electroplating is determined by their purpose and type of coating. Surface cleanliness depends on how the parts are prepared before electroplating. Polishing products with a lower initial surface finish significantly increases the processing time, which reduces the productivity of the equipment.\u0000It has been established that electrochemical and chemical polishing have several advantages over mechanical polishing. They do not require the physical effort of the worker, which reduces the complexity of finishing operations. Many products of various shapes and sizes can be processed simultaneously, which is not feasible when polishing with circles.\u0000Electrochemical polishing has become more widespread in industry. With its help, a greater smoothing and more intense gloss of the metal surface is achieved than with chemical polishing. The use of this process in preparation for electroplating reduces the number of operations and transitions and improves product quality by increasing the adhesion strength of the coating to the base metal.\u0000Keywords: Machini","PeriodicalId":246138,"journal":{"name":"ETM - Equipment, Technologies, Materials","volume":"249 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129788376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
