Friction Performance of Self-Emulsifying Esters and Organic Phosphate Esters Mixed Aqueous Solution on the Surface of TB6 Titanium Alloy

Water-based lubrication, due to the poor film-forming ability of water, faces challenges in achieving effective lubrication for titanium alloys. This study systematically investigates frictional performance phosphorus-based extreme pressure (EP) additives and self-emulsifying esters (SEE) on surface alloy (TB6) under different pressures temperatures. The core lubricant consists SEE with nonylphenol polyoxyethylene ether phosphate ester (NPEP), oleyl (POEP), alcohol (AEP). Results show that significantly improves aqueous solution, while forms a strong chemical adsorption film via P-O-Ti covalent bonds, enhancing strength lubricating film. combination water-based solution enables Particularly, mixture POEP demonstrates excellent synergistic effects, making it an ideal blend cutting fluids elucidates mechanisms action ranges between additives, providing important guidance development promotion fluids.
