Performance of hydraulic oils and its additives in fluid power system: A review

Abstract The main objective of this paper is to analyze various hydraulic oils and the effect additives like nanomaterials in order increase lubricity, counter friction, reduce wear, etc. A detailed list focused review which will enhance performance working fluid by enhancing lubrication, modifying viscosity cleaning engine deposits. Mineral or Synthetic hydrocarbon blends are used derive lubricants. Although they lack properties their own fulfill requirements set Original Equipment Manufacturers (OEMs). By using mineral advantages can be obtained. Various such as metal chalcogenides, soft metals, carbon-based materials, available via mechanisms rolling effect, protective film etc., change required. Similarly, added index improvers, anti-wear agents improve oil eliminating negative improving life fluid. These play a crucial role sustainability size optimized get better tribological characteristics. increasing usage these high country projected register compound annual growth rate (CARG) more than 1.5% during forecast period (2021-2026). focusses on improved when Hydraulic Fluid serve reference for future developments application nanotechnology oils.
