Hydroxyapatite (HA) coated CaO-SiO2-B2O3-Na2O glass composites prepared by a hydrothermal coating method were soaked in four kinds of solutions to evaluate the dissolution behavior and the chemical stability. 0.5 mol/l HCl and 0.5 mol/l HNO3 were used as acidic solution, and 5% physiological saline and sodium lactate compound solution as the neutral physiological solution. It was found that HA coated glass composites had the better chemical stability and the corroding-resistance ability. The dissolution behavior of the HA coating was mainly correlated with the phase composition of the as-received HA coating and its microstructure as well as the pH value of the solution.
采用水热涂层法制备的羟基磷灰石（HA）涂层CaO-SiO2-B2O3-Na2O玻璃复合材料被浸泡在四种溶液中，以评估其溶解行为和化学稳定性。0.5mol/L的HCl和0.5mol/L的HNO3用作酸性溶液，5%的生理盐水和乳酸钠复合溶液用作中性生理溶液。结果发现，HA涂层玻璃复合材料具有更好的化学稳定性和耐腐蚀能力。HA涂层的溶解行为主要与其初始HA涂层的相组成及其微观结构以及溶液的pH值相关。
