Abstract

The effects of surface treatment procedures as recommended by the American Society for Testing and Materials on the surface of unalloyed titanium implants were examined. Solid surface tension assessment suggested that the two-liquid Zisman plots were not sensitive to polar components and resulted in trends different from the two-liquid Kaelble plots. Raman studies did not show any crystalline order and X-ray photoelectron spectroscopy results indicated that the surface layers were composed primarily of a TiO/sub 2/ type stoichiometry along with 3 hydrocarbon overlayer. The surfaces also contained varying, although minute, amounts of surface contamination.

非合金钛种植体表面的评价
研究了美国材料与测试学会推荐的非合金钛植入体表面处理程序的效果。固体表面张力评价表明,两液Zisman图对极性分量不敏感,其变化趋势与两液Kaelble图不同。拉曼光谱没有显示出任何晶体秩序,x射线光电子能谱结果表明,表层主要由TiO/ sub2 /型化学计量组成,并有3个碳氢化合物覆盖层。这些表面也含有不同数量的表面污染,尽管数量很小。
