PLASTICS AND THE CORROSION OF IRON AND STEEL Available to Purchase

With present‐day moulding and extrusion techniques there is a wide range of articles that can be made from solid plastics and there is an ever‐increasing market for these products in industry and the home. Despite the attractive finish of these plastics articles and their ability to withstand corrosion and mechanical damage, there are objections to the use of the solid material for some applications. From an engineering point of view, there are difficulties of rigidity and mechanical strength, whilst economy also rules out the use of solid plastics in many cases, since, whilst it may be possible to mass‐produce large quantities of moulded plastics articles for domestic use, where there is a very large market potential, it is another thing to produce small runs of specialised engineering products economically. For these reasons there is an ever‐increasing demand for plastics finishes to both standard and purpose made metal goods either to protect the base metal or to produce an attractive finish.
