Наиболее высокая коррозионная активность сплава выявлена на начальной стадии выдержки в растворе (первые 12 мин). Установлен механизм коррозионной деградации материала, заключающийся в инициировании разрушения на границах зерен вследствие образования микрогальванических пар. Это объясняется присутствием в сплаве интерметаллидной фазы Mg2Ca, являющейся анодной по отношению к α-матрице магния. Предложена модель формирования слоя продуктов коррозии на поверхности сплава при его выдержке в MEM.\u0000 The paper presents results of study of electrochemical activity of the Mg–0.8Ca bioresorbable alloy in a medium for the cultivation of mammalian cells – the minimum essential medium (MEM). The highest corrosion activity of the alloy was revealed at the initial stage of exposure in the solution (for the first 12 minutes). The mechanism of corrosion degradation of material has been determined and it is characterized with initiation of the destruction at grain boundaries caused by the formation of micro-galvanic couples. It is explained by the presence of Mg2Ca intermetallic phase which is anodic against α- magnesium matrix. A model of formation of corrosion products layer on alloy`s surface during the exposition in MEM solution is proposed.","PeriodicalId":401413,"journal":{"name":"Вестник ДВО РАН","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133965074","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}

Получены зависимости данной величины от таких параметров, как максимальное значение и скорость изменения напряжения, а также от размеров оксидируемого изделия. Исследована зависимость защитных свойств ПЭО-покрытий, получаемых на магниевом сплаве МА8, от максимальной плотности тока формирования. Проведены морфологические и электрохимические исследования полученных гетерооксидных слоев с целью выявления корреляции свойств покрытий с плотностью тока формирования. Методами сканирующей электронной микроскопии и потенциодинамической поляризации изучены основные защитные свойства ПЭО-покрытий. Результаты свидетельствуют об увеличении толщины и пористости покрытий при росте значений плотности тока формирования. Показано, что при переходе от низких (2 мА/мм2) к высоким (до 12 мА/мм2) максимальным значениям плотности тока поляризационное сопротивление имеет максимум в области значения 4 мА/мм2, что свидетельствует об оптимальном режиме формирования ПЭО-покрытий с высокими барьерными свойствами.\u0000 It is established that in the potentiodynamic coating-formation mode by plasma electrolytic oxidation (PEO), the electrochemical and morphological properties of the resulting surfaces can be adjusted using the maximum current density. In this paper, the dependences of this value on such parameters as the maximum value and the rate of voltage change, as well as on the size of the oxidized product are obtained. The dependence of the protective properties of PEO-coatings obtained on magnesium alloy MA8 on the maximum density of the formation current is studied. Morphological and electrochemical studies of the obtained heteroxide layers were performed in order to identify the correlation of the coating properties with the density of the formation current. The main protective properties of PEO-coatings have been studied using scanning electron microscopy and potentiodynamic polarization. The results obtained indicate an increase in the thickness and porosity of coatings with an increase in the values of density of the formation current. It is shown that during the transition from low (2 mA/mm2) to high (up to 12 mA/mm2) maximum values of the current density, the polarization resistance has a maximum in range of 4 mA/mm2, which indicates the optimal mode of formation of PEO coatings with high barrier properties.","PeriodicalId":401413,"journal":{"name":"Вестник ДВО РАН","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130104858","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}
