The plasma electrolytic oxidation of the titanium alloy OT4 was studied; the characteristics of the resulting coatings were determined–thickness, breakdown potential, corrosion current density, and X-ray phase; micro-X-ray spectral analysis was performed, and the morphology of the coatings was studied by scanning electron microscopy. We studied the effect of plasma electrolytic oxidation of OT4 and additional treatment of PEO coatings on the corrosion resistance of the aluminum alloy D16 (An.Ox.nchr, anodic treatment in chromate solutions) in contact with the titanium alloy in structurally similar samples.

钛合金的等离子体电解氧化可保护相邻的铝合金元素免受接触腐蚀

研究了钛合金OT4的等离子体电解氧化。确定了最终涂层的特性-厚度，击穿电位，腐蚀电流密度和X射线相；进行显微X射线光谱分析，并通过扫描电子显微镜研究涂层的形态。我们研究了在结构相似的样品中OT4的等离子体电解氧化和PEO涂层的额外处理对与钛合金接触的铝合金D16（An.Ox.nchr，铬酸盐溶液中的阳极处理）的耐腐蚀性的影响。
