Meta surfaces are degreased and derusted in baths based on hydroch loric acid and sulphuric acid. Apart from containing surfac- tants, these formulations incorporate corrosion inhibitors to prevent the base meta from being attacked. Corrosion inhibitors are also expected to accelerate or, at least, not to impair the remova of oxides. Corrosion inhibitors that have a passivating action on a meta surfaces are preferred to those with a specific action on certain metals, because many of the materials that are encountered in practice consist of combinations of different metals and a oys. One of the purposes of pickling is to obtain a smooth surface, which implies that some of the meta on the surface wi be consumed, but it is important to ensure that the surface is not attacked too strongly. Korantin PP and Korantin PM Korantin PP and Korantin PM are derived from acetylene. T hey are very effective for protecting steel and aluminium from corrosion in acidic and neutral media. Korantin PP and Korantin PM are much more effect
