Abstract
A method for coating a plumbing component (1), comprising at least the following steps: a) providing the plumbing component (1), wherein the plumbing component (1) has at least one liquid channel (2); and b) at least partially coating an inner surface (3) of the at least one liquid channel (2) with a coating (4), wherein the coating (4) has at least one layer (5), which comprises copper.
Claims10
A method for coating, comprising:
- a) providing a plumbing component (1) comprising at least one liquid channel (2);
- and
- b) at least partially coating an inner surface (3) of the at least one liquid channel (2) with a coating (4),
- wherein the coating (4) consists of a first layer (5) consisting of copper directly coated on the inner surface (3) of the at least one liquid channel (2), and a second layer (6) consisting of a nickel phosphorus alloy directly coated on the first layer (5), and optionally a third layer (7) consisting of chromium directly coated on the second layer (6), optionally, when the third layer (7) is present, a fourth layer (8) consisting of a zirconium compound, a chromium compound or a titanium compound directly coated on the third layer (7), and optionally, when the third layer (7) and the fourth layer (8) are present, a fifth layer consisting of a mixture of a zirconium compound, a chromium compound and a titanium compound directly coated on the fourth layer (8).
