摘要

摘要为了使钛合金植入物在人体中具有更好的耐腐蚀性，通过微弧氧化在Ti6Al7Nb表面添加含硒涂层。结果表明，添加硒元素后镀层厚度增大，粗糙度降低。XRD、SEM和XPS分析表明，硒元素成功加入到涂层中。动态极化曲线和EIS表明，制备的样品在SBF溶液中具有较好的耐蚀性，(icorr)和(Ecorr)分别为2.695 × 10−8 A·cm−2和0.101 V。添加硒有助于提高样品在体液中的生物耐腐蚀性。关键词:微弧氧化;seo2钛合金;耐蚀性;涂层;本研究得到西南石油大学油气储层地质与开发国家重点实验室开放基金(PLN2021-20)资助。

Effect of SeO ₂ on corrosion resistance of micro-arc oxidation

ABSTRACTIn order to make titanium alloy implants have better corrosion resistance in the human body, selenium-containing coating was added to the surface of Ti6Al7Nb through micro-arc oxidation. The results indicate that the coating has a higher thickness and lower roughness after the addition of selenium element. XRD, SEM, and XPS analysis showed that selenium element was successfully added into the coating. Then the dynamic polarization curve and EIS indicate that the prepared samples have better corrosion resistance in SBF solution compared to the unadded samples, (icorr) and (Ecorr) are 2.695 × 10−8 A·cm−2 and 0.101 V, respectively. The addition of selenium helps to improve the biological corrosion resistance of the sample in body fluids.KEYWORDS: Micro-arc oxidationSeO2titanium alloycorrosion resistancecoatingsroughnessthicknessSBF solution Disclosure statementThe authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.Additional informationFundingThis work was supported By Open Fund(PLN2021-20 ) of State Key Laboratory of Oil and Gas Reservoir Geology and Exploitation (Southwest Petroleum University).
