Abstract (en)
[origin: WO2013005114A2] The invention relates to a process for producing a bonding layer on a surface (3) of a titanium material (5). The process comprises the steps: introduction of the surface (3) into an aqueous alkaline solution comprising sodium hydroxide in a concentration in the range 100 - 300 g/l, sodium tartrate in a concentration in the range 20 - 200 g/l, methylglycinediacetic acid Na3 in a concentration in the range 5 g/l - 60 g/l, pentasodium triphosphate in a concentration in the range 2 g/l - 20 g/l, and application of a voltage (13) between solution and titanium material (5) for a prescribed period of time to produce the layer by anodic oxidation of the surface (3).
