A method for reducing the solubility of copper ions of tubes made of copper or copper alloys, as well as copper tube with a reduced copper solubility

摘要

A method for reducing the solubility of copper ions from in particular with aggressive waters or other specific for copper aggressive media, in particular water having a ph - value of less than 7, which come into contact tubes made of copper or copper alloys, wherein the with aggressive waters or other specific for copper aggressive media, in particular water having a ph - value of less than 7, which come into contact surfaces of the copper objects with a coating of according to the sol - gel - method obtained ormocer^® Nanocomposites are provided, wherein the surfaces in front of the coating degreased and radiated or be oxidized, wherein the ormocer^® Nanocomposites, from ceramic or glass-like materials and formed with temperatures between 100°C. and 400°C. under pressure by the fill and rinse-off "- method are applied, wherein, in the case of a part of the same distances below 0,5 nm layer thicknesses between 0,5 μm and 3 μm are produced.
