Summary: | Water–glycol fire-resistant Hydraulic Fluid (HFC) is now widely used in marine equipment. However, the issue of seawater seepage into the equipment during operation is inevitable, resulting in the mixing of hydraulic fluid with seawater. This study systematically investigated the effects of different low concentrations of seawater on the friction, corrosion, and extreme pressure characteristics of HFC. The research findings indicate that the presence of seawater leads to a deterioration in the friction and wear performance of HFC. Furthermore, as the seawater concentration increases, the last non-seizure load (

) of HFC gradually decreases. Seawater also affects the corrosion resistance performance of HFC. When the seawater concentration is high, oxidative corrosion phenomena can be observed on the surfaces of the friction pair. Correspondingly, with the introduction of seawater, the wear rate of the friction pair significantly increases. Therefore, the introduction of seawater reduces the lubrication performance and

value of HFC, leading to serious corrosion wear of friction pairs. This work contributes to ensuring the reliable operation of hydraulic systems in marine working environments and provides data support for the application of hydraulic fluids. |
