摘要

在含0.6mmol/L Ca2+ 离子和0.36mmol/L H2PO4-离子的电解液中加入2.4mmol/L柠檬酸根离子进行钛表面阴极电沉积. 结果表明柠檬酸根离子延长了HA晶体的形核孕育期, 并且晶体形貌由规则的六棱柱变化为细尖锥状. 通过沉积电流, 涂层增重, 晶形变化等规律对整个沉积过程做出阶段性划分（吸附期、孕育期、爆发生长期、次层生长期和平衡期）, 并对各阶段的微观过程生长机理进行了探讨, 尝试建立了含柠檬酸根电解液中电解沉积HA晶体的生长模型.

Abstract

During electrolytic deposition process of hydroxyapatite(HA) on Ti surface, 2.4mmol/L citrate is added into the electrolyte containing 0.6mmol/L Ca2+ ion and 0.36mmol/L H2PO4- ion. The results show that the incubation period of the HA is prolonged significantly, and the HA crystals take the morphology of needlelike cone rather than the typical hexagonal prism. Through analyzing the deposition current, coating weight increment and crystal morphology changes, the whole deposition process is divided into 5 procedures: adsorption period, incubation period, eruptive growth period, extra-layer growth period and balanced growth period. Based on the further discussion of micro-mechanism of each period, the HA crystal growth model during electrolytic deposition process is proposed.
