Corrosive agent constitutes a major problem for constructions located in coastal areas, since it keeps affecting their durability. This phenomenon, in synergy with moisture and high temperatures, leads to premature deterioration of the structures. Under these conditions, the need for management of the problem of resistance of steel against corrosion is an issue of paramount importance and a challenge to the structural integrity and reliability. The paper aims to discuss these issues.

The need for management of the problem of resistance of steel against corrosion is an issue of paramount importance and a challenge to the structural integrity and reliability. In the present study, an effort was made to increase the corrosion resistance of the high strength and ductility dual-phase steel B500c category, with the use of different shot blasting processes, without any interference in the chemical composition or in the production mode. In particular, shot blasting treatment was used for both cleaning and creating compressive stresses on the surface of steel bars, according to the pertinent protocols. The modified samples were studied via both conventional characterization methods and electrochemical techniques.

Through the whole surface treatment process of B500c steel, a positive impact came about not only the corrosion resistance, but also the mechanical performance.

Shot blasting process aims to increase the corrosion resistance of high ductility dual-phase steel (B500c), without any interference in the chemical composition or in the production mode.

A FIVE‐AXIS contouring‐type numerically‐controlled shot peening machine has solved the problem of strengthening certain critical structural components of the General Dynamics F.111 variable sweep wing tactical fighter/bomber which is being built at Fort Worth for the United States Navy, the United States Air Force, the Royal Australian Air Force and, possibly, for service with the Royal Air Force. Apart from the vital wing support assembly which must carry the entire weight of the aircraft during flight, over thirty other F.111 components are automatically shot peened with absolute uniformity in this tape‐controlled machine to give the necessary fatigue strength—among the components being 25 ft. long milled wing skins.

Discusses the use of a corporate Internet in a geographically‐spread consulting firm, James Martin & Co., to share ideas, vision, client information and results. Illustrates with examples. Applications include a quarterly Employee Attitude Survey and regular discussion forums. Proposes that a well‐designed corporate intranet is a highly effective method of making intangible vision and mission pledges more tangible.

METALLISING or metal spraying is carried out by heating powder or wire in the flame of a gun and then projecting it on to a suitably prepared surface to form a coating.

As technical manager for a large group of paint manufacturers and painting contractors, the author is able to evaluate blast primers from the viewpoint of both supplier and user.

The conditions to which marine paints are subjected are undoubtedly very much more severe than those which any similar types of paint meet on land. Conditions of application, which are more often than not bad, add further complications. In dry‐dock painting the ship must undock to schedule and painting must, therefore, go on regardless of rain, frost and fog. As a result, most marine paints and compositions for the outer hull must be a compromise between the ideal and the practical, rather than the best possible material which could be used under perfectly controlled conditions.

From November 29 to December 2 the Empire Hall at Olympia, London, will be given over to what will probably be the world's largest display of products, processes and services for use in the prevention or limitation of corrosion. Over 120 stands will be shared by 94 exhibitors, each contributing in some way or in many ways to this cause. The extensive preview in the following pages is divided into sections. However, the grouping is general and reflects only one aspect of a company's activities. Therefore a complete examination of items is recommended.
