摘要:
A method for the biomimetic treatment of a metal substrate, said metal being selected from the group consisting of titanium, tantalum, titanium alloys and tantalum alloys, comprising the steps of: (a) subjecting the metal substrate to an anodic spark deposition (ASD) treatment in an aqueous solution comprising sodium silicate hydrate (Na 2 SiO 3 -2H 2 O), β- glycerophosphate (β-GP), calcium acetate hydrate (C 4 H 6 CaO 4 -H 2 O) and sodium hydroxide (NaOH); and (b) immersing the metal substrate subjected to the ASD anodic deposition treatment in a solution of sodium hydroxide (NaOH). Moreover, the present invention also relates to a deposition aqueous solution comprising sodium silicate hydrate (Na 2 SiO 3 -2H 2 O), β- glycerophosphate (β-GP), calcium acetate hydrate (C 4 H 6 CaO 4 -H 2 O) and sodium hydroxide (NaOH).
摘要:
The present invention relates to an osteointegrative interface for implantable prostheses and to a method for the treatment of the osteointegrative interface (1); the method can modify the surface of the osteoingrative interface, which is made of transition metals such as titanium, tantalum and their alloys, in order to produce so-called “biomimetic” surfaces which have innovative compositional and morphological characteristics, and is based on the use of an anodic spark deposition (ASD) anodizing technique performed firstly in a Ca-GP solution and subsequently in a Ca (OH)2 solution.
