A Study on HA Titanium Surface with Atomic Force Microscope (AFM)

摘要

Three kinds of titanium surface especially the HA surface are analyzed. Titanium was treated by 3 kinds of methods that were acid & alkali, calcic solution and apatite solution. Samples were observed by optic microscope and atomic force microscope (AFM). The typical surface morphology of the acid and alkali group is little holes, and on the two HA surface the tiny protuberances is typical. The surface treated by apatite solution was smoother than the two formers. The rough surface treated with acid and alkali was propitious to Ca+, P- and proteins’ adhesion, and the relatively smooth HA surface was of benefit to the cell adhesion.
