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

摘要： A highly wear resistant sliding element for use in structural engineering comprises at least one sliding surface made from ultra high molecular weight polyethylene (UHMWPE). Advantageously, the molecular weight of such ultra high molecular 5 weight polyethylene (UHMWPE) is higher than 6.5x10 6 g/mol.

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.
