TY - JOUR AB - Watercontaining fluids are widely used in hydraulic applications where there is a significant risk of fire, as in underground mining and metal working applications. Although primarily intended as power transmitting media, hydraulic fluids need to possess a modicum of lubricating ability to limit wear, seizure and contact fatigue of pumps and other rubbing parts. Unfortunately waterbased hydraulic fluids generally show significantly poorer wear and rollingcontact fatigue performance than mineral or synthetic oilbased fluids of similar viscosity and this means that pumping equipment usually has to be derated when used with waterbased fluids. This paper examines the poor wear and fatigue performance of waterbased fluids and discusses, in some detail, the origins of this poor performance and the ways it can be mitigated.
