The invention relates to a method which is used to produce a permanent support layer on precious metal surfaces by coating solutions which are based on polysilazane. Said method is used to coat surfaces made of precious metal or precious metal alloys with a solution containing a polysilazane of formula (1), wherein n is measured in such a manner that the polysilazane has an average molecular weight from 150 - 150.000 g/mol, in addition to a solvent and a catalyst. The invention is characterised in that a silane based primer which contains sulphur and which is used to improve adherence, is applied to the object which is to be coated prior to the coating with the polysilazane solution. The invention also relates to coatings which are produced according to the inventive method.
L'invention concerne un procédé pour enduire des surfaces en métal précieux ou en alliages de métal précieux avec une solution contenant un polysilazane de formule (1), dans laquelle n est calculé, de sorte que le polysilazane présente un poids moléculaire moyen en nombre de 150 à 150 000 g/mol, ainsi qu'un solvant et un catalyseur. Ce procédé se caractérise en ce qu'un primaire à base de silane, contenant du soufre et destiné à améliorer l'adhérence, est appliqué sur l'objet à enduire avant l'enduction avec la solution de polysilazane. Cette invention concerne également des revêtements réalisés par le procédé de l'invention.
