GLASS WITH AN ATTACHED COATING FILM, ITS MANUFACTURING METHOD AND MODIFIED GLASS SUBSTRATE Russian patent published in 2023 - IPC C03C23/00 C03C17/00 

FIELD: coating films.

SUBSTANCE: invention relates to a product with an attached coating film, forming a medical glass vessel. The glass with a coating film attached according to the present invention includes a glass substrate and a coating film on at least a portion of the surface of the glass substrate, wherein the area from the surface of the glass substrate on the side of the coating film to a depth of d1 100 nm is a modified layer, which, according to at least partially, has a microcrystalline structure. The coating film is applied over the modified layer. The coating film is a silicon-free DLC film, a silicon-containing DLC film, a silicon oxide-based film, or an amorphous fluoropolymer film. The technical result of the invention is to obtain a product with high transparency, high sliding properties, sufficient heat resistance.

EFFECT: peeling of the silica component in the glass, as well as washing out of other glass components, is less likely, while protein adsorption is reduced, and peeling of the coating is eliminated.
