Abstract
DE 102009054605 B3 UPAB: 20110624 NOVELTY - The open-cellular, titanium metal foam comprises a three-dimensional network of webs connected to each other, whose covering surface (4) consists of titanium and has a roughness of less than 2 mu m in smooth web surface. The metal foam is produced by a Schwartzwalder method. The web has a smooth surface with roughness of less than 1 mu m. The surface area of the web consists of 85% of titanium, where the residue is titanium compound and/or titanium alloy component. The titanium-alloy is Ti6Al7Nb and Ti6Al4V. The web is present in interior cavity (6) of the foam. DETAILED DESCRIPTION - The open-cellular, titanium metal foam comprises a three-dimensional network of webs connected to each other, whose covering surface (4) consists of titanium and has a roughness of less than 2 mu m in smooth web surface. The metal foam is produced by a Schwartzwalder method. The web has a smooth surface with roughness of less than 1 mu m. The surface area of the web consists of 85% of titanium, where the residue is titanium compound and/or titanium alloy component. The titanium-alloy is Ti6Al7Nb and Ti6Al4V. The web is present in interior cavity (6) of the foam and has cracks (7) and pores (8) in its wall. The covering surface of the web has pores, whose portion is less than 5% related to the surface. The pores in the covering surface of the web have maximum dimension of less than 1 mu m. USE - Open-cellular, titanium metal foam useful for medical implants. ADVANTAGE - The open-cellular, titanium metal foam can be manufactured with improved roughness.
