摘要 |
<p>A method of reducing the quantity of lead released by water-system components made of metal alloys containing lead when they are in contact with liquids intended for making beverages for human use comprises at least the following steps in sequence:
- preliminary reduction of the quantity of lead contained in the material constituting the components,
- coating of the components thus treated, at least on the surface which is to come into contact with the liquids, by the chemical deposition of a tin layer,
- coating of the water-system components, at least on their surface that was treated by the deposition of the tin layer, by the electrolytic deposition of a covering metal alloy.</p> |
