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.
