The thesis also presents information ofgeneric interest in corrosion of carbon steel and other materials of interest in subsea environments. The materials chosen in this research are those which are used extensively in subsea applications especially in Directional Control Valves (DCV) and piping operating with hydraulic fluids namely: (1) carbon steel, (2) stainless steel, and (3) cermet alloys (WC-Ni and WC-Co).

The main corrosion challenges associated with the use of seawater are addressed in this study, particularly on how to extend the material life when corrosion attack is likely to be very severe. It provides a high degree of corrosion protection, for all engine cooling systems whether they are predominantly of aluminium or ferrous construction, Unit 13, Oakney Wood Avenue, Selby Business Park, Selby, North Yorkshire, YO8 8FQ, Phone: 01757 706 996. At Oilgear we acknowledge that our customers demand more than on time delivery of quality goods and services at competitive prices, so we go beyond these basic performance requirements to provide much more in our hydraulic solution packages. These fluids use state-of-the-art ashless, zinc-free additive technology. The ECOSURE range has an excellent viscosity temperature profile and unlike many high VI mineral hydraulic fluids, ECOSURE does not use viscosity index improvers, so will not shear down in use.

ECOSURE products achieve biodegradability of greater than 60% in the 28 day OECD 301B test and are considered non-toxic in the marine environment based on the following results: Biodegradable fully saturated high oxidatively stable hydraulic fluid ISO 100, Biodegradable fully saturated high oxidatively stable hydraulic fluid ISO 32, Biodegradable fully saturated high oxidatively stable hydraulic fluid ISO 46. which is developed by the In this research the effects of temperature, sulphate to chloride ratio and oxygen were studied on corrosion performance of DCV materials and compared the performance in seawater with a typical commercial hydraulic fluidHW443. However, cermets alloys (WC-Ni and WC-Co) which consist of metals and ceramics may exhibit both active and passive trends. Therefore, it is clear that by changing the sulphate/chloride ratio in seawater and adding green corrosion inhibitor similar performance to that compared to the use of commercial hydraulicfluids yet reduce the environmental harm on discharge could be attained. As an active material, carbon steelcorrodes in a general way whereas passive materials such as stainless steel are more prone to localised corrosion which is often more catastrophic and difficult to predict and detect.
