The last 20/30 years have seen many major technological changes in industry. The growth of the aviation gas turbine as a prime mover in the transportation industry, the use of nuclear energy in the power generation industry and the probing of outer space are but three examples of engineering achievements which have created numerous problems for materials. Among these problems the difficulties of providing adequate lubrication under new and extreme conditions has assumed great importance, requiring the development of synthetic lubricants fashioned to cope with particular environments. But before describing the various types of synthetic lubricants now available for use by industry let us first consider the environmental factors important to lubrication and lubricants.
