Effect Of Several Water-based Additives On The Tribological Properties Of Glucose Microemulsions

The hottest topics on lubricants are the issues of environment and energy sources today. The mineral oil-based lubricants would gradually disappear from lubricant markets because of the waste of strategic resource and the pollution to environment. It becomes to a more and more important research aspect that the way of searching for water-based lubricants which have excellent lubrication and wide application area. The paper takes saving resources and protecting environment as the initial point, directs at the bad performances of water-based lubricants on lubricating, anti-fatigue and anti-rust properties, focuses on the way to improve the properties, investigates the best approach to elevate the performances based on the results of large numbers of experiments.In the paper the main innovation and research harvests are as follows:1. Two ways of improving the extreme pressure and anti-wear properties are investigated: improving the lubrication properties by replacing the water with glucose-containing water with the concentration of 5% as the base fluids of lubricants and adding emulsifier and extreme pressure and anti-wear additives to water-based lubricants. The results show that both can improve the load carrying capacity and welding load, and reduce the friction coefficient and wear as well.2. The results of end-face friction and wear tester on the steel/aluminum friction pairs show that glucose has little impact on reducing the friction coefficient and wear, composite additives especially doped with sulfur have good performances.3. The results of fatigue experiments on the steel/steel friction pairs show that glucose can improve the anti-fatigue property under a wretched condition and lubricants doped with sulfur, phosphorus raise the anti-fatigue property markedly.4. The results of a developed experiment on the anti-rust properties of several fluids show that the single glucose can't improve this property of water-based lubricants.It provides a reference to water-based lubricants researchers by the large numbersof data and points out a new direction of developing lubricants.
