| 摘 要： | 采用3种不同的方法即不作处理，酸和碱处理但不加热、酸和碱处理后600℃加热对商用纯钛进行表面处理，然后将样品浸泡于仿生溶液中2周后，经过处理的两组样品表面均形成一层薄的钙磷涂层，SEM和EDX分析表明：酸碱处理再经600℃加热组较单纯的酸碱处理组涂层晶体构型均一；XRD分析表明晶体组成主要为含有少量氯元素的羟基磷灰石。

| Abstract: | All samples were divided into three groups and subjected to three different surface treatments, i.e. untreated group, group etched with mixed acid of 1:1 HCl and H2SO4 followed by immersion in 6N NaOH solution at 60 degrees C for 24 h and group etched with mixed acid of 1:1 HCl and H2SO4 followed by immersion in 6N NaOH solution at 60 degrees C for 24 h then heated at 600 degrees C for 1 h. After soaked in simulated body fluid for two weeks, a thin calcium phosphate coatings was precipitated on the surfaces of the two treated samples. Results of SEM and EDX showed that calcium phosphate coatings on the surfaces of the titanium samples etched and heated were more even than the titanium samples etched without heating. The analysis of XRD demonstrated the main component of calcium phosphate coating was hydroxyapatite. |
