Quite often in everyday service ‘stainless’ steels stain and ‘rustless’ alloys rust. In particular, the straight chrome/iron nickel‐free alloys have frequently exhibited early signs of severe tarnishing in service. Electrolytic polishing enhances the corrosion resistance of certain metals by forming very thin passive films—probably oxides—on these surfaces. This applies mainly to ferritic stainless alloys but also to some of the austenitic steels, to aluminium, brasses and to certain carbon steels. This article considers the nature and properties of the films and discusses practical applications.

Oil Terminal Protection. The cathodic protection design for the piling of the new North Pier, Mina al‐Ahmadi, Kuwait, consists basically of silicon anodes. The piles are coated with a coal‐tar enamel and the steel superstructure is coated with chlorinated‐rubber paint. Consideration was given to the filling of the piles with water or oil to prevent internal corrosion, but in view of possible damage to piles and loss of liquid they were filled with a sand‐cement mix.

FRENCH INSTITUTE OF CORROSION. The Centre Francais de la Corrosion (Cefracot) was recently instituted in Paris. It aims at co‐ordinating information on the science, technology and application of corrosion and corrosion proofing, and is a non‐profit‐making organisation. Cefracor is to take up contacts with all French institutions, and those abroad, devoted to similar ends, and is already a member of the European Federation of Corrosion. The centre has its headquarters at 28 rue Saint Dominique, Paris, 7e.
