The invention relates to a process of reducing scaling of a metal surface exposed to an aqueous solution from which scale may form after a period of exposure. The process comprises applying a cathodic potential to the surface for at least some of the period of exposure. In some cases, e.g. when an article is made of a ferrous metal, it is advantageous to coat the article with a different metal (e.g. copper or an alloy of copper) before applying the cathodic potential to avoid hydrogen generation and excessive current flow. An article to be protected from scaling may also advantageously be electrically isolated from other parts of an apparatus.

La présente invention concerne un procédé qui permet de réduire l'entartrage d'une surface métallique exposée à une solution aqueuse pouvant provoquer un entartrage après une période d'exposition. Le procédé de l'invention consiste à appliquer un potentiel cathodique sur ladite surface pendant au moins une partie de la période d'exposition. Dans certains cas, p.ex. lorsqu'un article est composé d'un métal ferreux, il est avantageux de recouvrir l'article d'un métal différent (p.ex. du cuivre ou un alliage de cuivre) avant d'appliquer le potentiel cathodique afin d'éviter la production d'hydrogène et un écoulement de courant excessif. Afin de mieux protéger un article de l'entartrage, on peut également l'isoler électriquement des autres parties d'un appareil.
