Substrate having a silver-ion containing titanium oxide coating having a silver content of greater than or equal to 0.2 of Ag/l of Ti to less than or equal to 0.4 of Ag/l of Ti, wherein the coating is X-ray amorphous and the hydrophobicity of the coating can be reduced persistently by illumination.

Hydrophobic coating and process for production thereof

Disclosed is a method for producing an implant coating that has a defined toxicity. The method is characterized by the following steps: i. a sol is produced from a biotoxic solution containing precious metal ions and a precursor solution for a titanium oxide; ii. an implant is coated by applying the sol in a sol-gel process; iii. the coating is pyrolyzed and sintered without admitting any light, the precious metal ion concentration in the dried coating ranging from 10 to 60 percent relative to the total weight of the dried coating; and iv. at least subareas of the coating produced without admitting any light are illuminated in order to reduce the toxicity of the dried coating to a predetermined measure.

Implant comprising a biotoxic coating and method for the production thereof

Process for producing a solar absorber coating, which comprises the steps: coating of a substrate with a titanium precursor solution to produce a titanium dioxide layer by the sol-gel technique and heat treatment of the coated substrate to pyrolyse and crystallize the layer, characterized in that silver ions are added to the titanium precursor solution prior to coating in such an amount that the heat-treated layer has a proportion by mass of silver in the range from 10% to 80% and pyrolysis and crystallization of the layer are carried out with illumination of the layer with visible light.
