Tailored Surface Roughness & Porosity of Titanium Bodies for Biomedical Use via Gas/Solid Displacement Reactions

Researchers at Purdue University have utilized a well-controlled gas/solid displacement reaction to provide a high and uniform concentration of fine-scale pores and protuberances on titanium surfaces. Such surfaces include external and internal surfaces, such as are present in porous titanium-bearing bodies. The sizes of such pores and protuberances can be tailored by the conditions used in this gas/solid displacement reaction. This process can yield titanium-bearing composite surfaces which can further aid in the bone formation process. Recent studies on porous Ti-bearing surfaces generated by the process of this invention have indicated that such surfaces exhibit enhanced responses by bone-forming cells.
