摘要
概述了几种主要钙磷酸盐(Ca–P)相的性质,包括CaHPO4·2H2O、CaHPO4、Ca8H2(PO4)6·5H2O、Ca3(PO4)2和Ca10(PO4)6(OH)2。阐述了多种在镁基体上制备Ca–P涂层的技术的特点及其优势,主要有仿生法、溶胶–凝胶法、微弧氧化法、电沉积法、等离子喷涂法及激光法。分析讨论了Ca–P涂层在生物医学领域应用上的几个关键因素(如表面化学特性、腐蚀速率、长期腐蚀行为、腐蚀过程的均匀性及结合力),展望了Ca–P涂层在生物医学上应用的发展前景。
The properties of some main calcium phosphate phases, including CaHPO4·2H2O, CaHPO4, CasH2（PO4）6·5H2O, Ca3（PO4）E,and Ca10（PO4）6（OH）2 were summarized. The characteristics and advantages of several technologies used for preparation of calcium phosphate coatings on magnesium substrates, such as biomimetic method, sol-gel method, micro-arc oxidation, etectrodeposition, plasma spraying, and laser cladding, were reviewed. Some critical factors including surface chemical properties, corrosion rate, long-term corrosion behavior, uniformity of corrosion process, and adhesion were analyzed and discussed for the biomedical application of Ca-P coatings on Mg and Mg alloys. The development prospect of Ca-P coatings for biomedical applications was described.
