Use of copper-based coatings for crops under glass covers, antiphytopathogenic coating glass and the method of obtaining antiphytopathogenic coatings

An antiphytopathogenic coating glass having a glass pane with a sputtered coating,

• the sputtered coating containing:
• copper in the amount of 10-90% and one of:
• titanium in the amount of 0.5-15%,
• zinc in the amount of 3-28%,
• tin in the amount of 1-20%,
• wherein the sputtered coating content is completed by an oxygen arising from obtained in process oxides.

A method for obtaining antiphytopathogenic coatings on a glass pane surfaces, the method comprising the steps of:

• placing the glass pane surface on rollers of an feeder;
• transporting the glass pane surface to an initial vacuum chamber, wherein an initial vacuum is generated;
• transporting the lass pane surface of the orevious step to a process vacuum chamber;
• wherein the initial vacuum chamber has a preliminary vacuum of 1.0·10−1 Pa;
• wherein the process vacuum chamber produces a process vacuum of 1.1·10−1 to 7.6.10−2 Pa.;
• Nextly, the reactive gas of 100-900 cm3/min is dosed and the impulse DC power supply is switched on;
• Wherein the methotid runs with an electrical current intensity of 30-45 A, an effective power 4.5-8.7 kW, and a circulating power 1.1-4.5 kW in the magnetic field generated in the chamber;
• wherein a moving speed is set to 1.9-9.2 m/min and the glass pane surface transported through a first magnetron of the process chamber with a glowing plasma using at least a two-component target, wherein the first component is copper;
• wherein the method produces a transparent coating layer with a thickness of 10-60 nm.
