A method for the production of coated glass with an increased strength, as well as glaser certificate produced according to the method

摘要

A method for producing a coated glass containing sodium -, in which the glass with a sol - gel - coating in the form of a multilayer interference layer and the glass is provided with the sol - gel - coating for curing of the coating at a temperature of more than 200°C. is tempered, characterized in that the thus coated glass according to the annealing of the sol - gel - coating is chemically pretensioned, in that the coated glass in a medium containing potassium - is mounted, so that sodium - ions of the glass to the surface and in regions close to the at least partially by potassium - ions to be exchanged, wherein the ion exchange through the annealed multilayer sol - gel - coating takes place in a.
