How to Prepare Topography for Improved Blood Coagulation and / or Cell Adhesion on Titanium or Titanium Alloy Bodies

摘要

To provide a process for preparation of a topography for improved blood coagulation and/or cell attachment on a body made of titanium or a titanium alloy.SOLUTION: The process includes the subsequent steps of: a) etching at least a portion of the surface of the body with a first etching solution including a mineral acid; and b) etching the surface etched in the step a) with a second etching solution different than the first etching solution, the second etching solution including hydrofluoric acid.SELECTED DRAWING: Figure 3
