CORROSION COMMENTARY Available to Purchase

WOOD AND CORROSION. Wood is one of the oldest materials used in the defence against corrosive substances—in this capacity it is an old‐timer in the chemical industry's structural materials. Corrosion occurring with wood as the medium stimulating attack is not as familiar, but it is a subject requiring increasing study by the Forest Products Research Laboratory. This centre's 1955 Report (obtainable from H.M.S.O., pp. 70, 4s. 6d. net) reveals that some 15% of the year's chemical enquiries concerned the corrosion of metal parts in wood/metal assemblies. Investigations are in progress on aluminium corrosion in wood, and a wide range of experiments covers most of the combinations of three types of aluminium sheet or plate, ten species of wood, and three classes of wood preservative. But indications of the causes of corrosion have not yet been given.
