The past decade has seen a rapid development in the range of techniques which are available to modify the surfaces of engineering components. This in tum has led to the emergence of the new field of surface engineering- the design of a composite system (coating plus substrate) that produces a performance which cannot be achieved by either the coating or substrate alone. With this expansion comes the problem of deciding on the correct surfacing technology for a given application. Clearly, to take full advantage of the benefits which surface engineering offers, there is a need to explain, in a...
