Non-toxic stripping methods for surface treatment
Surface treatment is a key technology used to fight corrosion for many industrial applications. Despite its toxicity, hexavalent chromium (Cr(VI)) has been widely incorporated into coatings. In the form of chromate compounds, it provides excellent corrosion protection to nearly all metals in a wide range of environments. What’s more, Cr(VI) is also used to remove the protective oxide layers from the treated surfaces. Until now, finding suitable alternatives has been difficult for lightweight metals such as aluminium. To address this, the EU-funded project Cr Free REAL is developing an innovative process for removing metal coatings, without deteriorating the aluminium substrate. If successful, the new process will permit the development of non-toxic uniform metal surfaces with no holes.
