METHOD FOR PRODUCTION OF A GLAZED PIECE PROVIDED WITH A MULTI-LAYER COATING

摘要

The invention relates to a method for production of a glazed piece provided with a multi-layer coating deposited by cathodic atomisation, a glazed piece provided with a multi-layer coating and a crowned or tempered glazed piece provided with a multi-layer coating. According to the invention, at least one first transparent dielectric layer is deposited, followed by a functional layer based on a material which reflects infra-red radiation. A first protective layer is then deposited with at most 3nm of a material having an electronegativity difference to oxygen of less than 1.9, followed by deposition of a second protective layer, with at most 7nm of a material with an electronegativity difference to oxygen of greater than 1.4. At least one second transparent dielectric layer is then deposited. The invention is particularly advantageous for the formation of glazed pieces with low emmissivity or for solar protection which are crowned or tempered after deposition of the coating.
