Claims16
An irrigation element flexible diaphragm of the sort suitable for positioning in an irrigation element comprising an inlet and an outlet such that a fluid passing through the irrigation element is forced to bear against said flexible diaphragm, the flexible diaphragm comprising:
- a core layer;
- and
- at least one protective layer formed on the core layer.
A method of making an irrigation element flexible diaphragm of the sort suitable for positioning in an irrigation element comprising an inlet and an outlet such that a fluid passing through the irrigation element is forced to bear against said flexible diaphragm, the method comprising:
- providing a core layer;
- and
- providing a protective layer on the core layer by a plasma assisted process.
A method of making an irrigation element flexible diaphragm of the sort suitable for positioning in an irrigation element comprising an inlet and an outlet such that a fluid passing through the irrigation element is forced to bear against said flexible diaphragm, the method comprising:
- providing a core layer;
- and
- providing a protective layer on the core layer by using at least one of the methods of sputtering, Sol-gel, co-extrusion, chemical vapor deposition and/or physical vapor deposition.
An irrigation element comprising an inlet, an outlet, and a flexible diaphragm positioned in the irrigation element such that a fluid passing between the inlet and the outlet is forced to bear against said flexible diaphragm, the flexible diaphragm comprising:
- a core layer;
- and
- at least one protective layer formed on the core layer.
