摘要:
采用溶胶-凝胶法在碱液预处理的钽片表面制备碳酸钙薄膜,然后分别采用磷酸氢二铵、磷酸氢钙及β甘油磷酸钠进行水热处理,合成羟基磷灰石薄膜。结构和成分分析表明,溶胶-凝胶法在钽表面形成了由密集的纳米颗粒组成的碳酸钙薄膜,在磷酸氢二铵和磷酸氢钙溶液中水热处理的试样表面形成了羟基磷灰石纳米晶体。水接触角和动电位极化测试表明,这两种溶液处理的试样均具有良好的亲水性和耐蚀性。
Abstract:
Calcium carbonate film was prepared by sol-gel method on the surface of tantalum sheets pretreated with alkaline solution. Then, (NH4)2HPO4, CaHPO4?2H2Oand disodium β-glycerophosphate were used respectively in hydrothermal treatment to synthesize hydroxyapatite films. The structural and compositional analyses showed that calcium carbonate film consisting of dense nanoparticles was formed on tantalum surface by sol-gel method. Hydroxyapatite nanocrystals were grown on surface of the samples hydrothermally treated with (NH4)2HPO4 and CaHPO4 solutions. The water contact angle and potentiodynamic polarization tests indicate that the samples treated with these two solutions have good hydrophilicity and corrosion resistance.
