METHOD FOR PREVENTING METAL LEACHING FROM COPPER AND ITS ALLOYS

摘要

A method for reducing or eliminating the leaching of undesirable metals by forming an inert, at least partial film comprising titanium and oxygen on copper or copper-alloy surfaces. Particularly, the surfaces are those of plumbing components such as faucets, valve components and the like, and more particularly those surfaces that are in water contact during use. Surfaces coated in accordance with the present invention may be the inner surfaces of a hollow object. The object in question may be a single component, e.g. a plumbing component, or an assembly of several such components.
