Novel Phosphate Organic Guanidine Salt Water-Based Additive with Integrated Anti-Friction, Anti-Wear and Anti-Corrosion Properties

Two new phosphate organic guanidine salt water-based additives (P4-G, P8-G) were synthesized, and their tribological properties and anti-corrosion performance were investigated. Friction tests revealed the lubricity and anti-wear performance of P8-G to be superior to that of P4-G. Moreover, it had g...

Summary:Two new phosphate organic guanidine salt water-based additives (P4-G, P8-G) were synthesized, and their tribological properties and anti-corrosion performance were investigated. Friction tests revealed the lubricity and anti-wear performance of P8-G to be superior to that of P4-G. Moreover, it had good anti-corrosion properties. In addition, the P8-G as the water-based lubricant additives have better friction-reducing, extreme-pressure and anti-wear properties than a commercial water-based lubricant additive of CCFS. The Three-dimensional profile, scanning electron microscope, and X-ray photoelectron spectroscopy were used to analyze the wear spot surface and clarify the friction mechanism. Overall, P8-G was found to exhibit excellent anti-friction and anti-wear properties, which can be attributed to its excellent adsorption properties on the metal surface and the tribochemical reactions with metal substrates to form stable tribochemical reaction films. More importantly, the system is pollution-free and is expected to develop into a highly efficient lubricant additive applied in water-based hydraulic fluids, which serves as a guide for the design and synthesis of water-based additives.
