摘要： The invention relates to a method for passivating a surface (25) of a metal part (3), wherein a calcium phosphate-containing conversion coating (5) that comprises oxides and hydroxides as well as carbonates of the material from the metal part, is created on the surface (25) in a passivation step using an aqueous passivation solution. According to the invention, the passivation solution for forming the conversion coating (5) includes at least one substance that acts as a chelating agent.

摘要： Provided is a process for the preparation of a silicone or fluorosilicone-coated solid substrate, which process comprises the following steps
a) providing a solid substrate having at least one surface to be coated,
b) bringing the surface to be coated in contact with a coating fluid comprising linear silicone or linear fluorosilicone molecules, and
c) irradiating the coating fluid in contact with the surface by UV light to photo-dissociate a silicon-carbon bond in linear silicone or linear fluorosilicone molecules contained in the coating fluid, and allowing them to form a new covalent bond to the surface of the solid substrate, thus providing a solid substrate having at least one surface that carries a coating comprising a layer of silicone or fluorosilicone molecules covalently grafted to the surface, and further comprising silicone or fluorosilicone molecules adhering non-covalently to the layer of the grafted molecules. Moreover, coated solid substrates are provided, which are obtainable by the process in accordance with the invention.-

摘要： The invention relates to a method for passivating a metal surface (25) of a light-weight metal part (3), wherein a conversion layer (5) is applied to the surface (25) of the light-weight metal part (3) in a passivation step (P). According to the invention, a passivation step (P) is carried out wherein an aqueous passivation solution is used to create a calcium phosphate-containing conversion layer (5) on the metal surface (25) of the part (3), said conversion layer (5) comprising oxides and hydroxides from the material of the part (3) and from the passivation solution and containing amino acids.
