Eco-friendly hydroxyapatite-based coating modified by polyvinylalcohol (PVA) was used as a protective layer for Mg AZ31 substrates. Anti-corrosion performance of coatings was examined in both sodium chloride 3.5 wt% and simulated body fluid (SBF) solutions. The best performance against corrosion was achieved in the one-step process with a PVA concentration of 0.05 wt.% and an immersion time of 60 minutes. The FE-SEM images also have shown that the irregularity of morphology was evident for the samples treated longer than 60 minutes. The results showed that the HA+PVA 0.05 wt.% coated AZ31 Mg alloy causes less corrosion of Mg in the SBF solution.

在聚乙烯醇 (PVA) 存在下改性羟基磷灰石基涂层用于植入物：腐蚀、结构和表面研究

由聚乙烯醇（PVA）改性的环保羟基磷灰石基涂层用作Mg AZ31基材的保护层。在氯化钠 3.5 wt% 和模拟体液 (SBF) 溶液中检查涂层的防腐性能。在 PVA 浓度为 0.05 wt.% 和浸泡时间为 60 分钟的一步法中实现了最佳的抗腐蚀性能。FE-SEM 图像还表明，对于处理时间超过 60 分钟的样品，形态的不规则性很明显。结果表明，HA+PVA 0.05 wt.% 涂层的AZ31 Mg 合金在SBF 溶液中对Mg 的腐蚀较小。
