Lubricant Performance

A type of water-based cold rolling fluid has been developed by adding TiO2 nanoparticles. The tribological behavior of nanoTiO2 water-based rolling fluid was investigated by using four-ball machine. The worn surfaces of the steel balls were analyzed by using OLYMPUS laser confocal microscopy. Results indicate that nanoTiO2 nanoparticles significantly improved the anti-wear properties in the way of micro-ball bearing and perfecting the tribological behavior of water-based rolling fluid. The cold rolling experiment shows that the nanoTiO2 water-based rolling fluid had a good rolling lubricant performance under the condition of concentration of 0.7wt.% for the upper limit. The nanoTiO2 water-based rolling fluid can not only decrease the minimum rolling gauge and the surface roughness of the work piece, but also prevent direct contact between roller and work piece which could lead to the rolled surface scratches and adhesion defects.

Effect of chemical structure of the aliphatic acid on rust-inhibiting properties and tribological behaviors of the water-based cutting fluid was studied in systematically. It was obtained that (1) the rust-inhibiting property became better with increase of the length of alkyl-chain of the aliphatic acid salts of triethanolamine. (2) The rust-inhibiting property of the aliphatic binary acid triethanolamine salts was better than that of the aliphatic monoacid triethanolamine salts. But the tribological behavior of the aliphatic monoacid triethanolamine salts was favor. Compared with base water, anti-wear and friction-reducing abilities of the soluble aliphatic acid triethanolamine salts would be improved greatly. (3) The adsorption and tribo-reaction films on the metal wear scar surface were monitored by auger energy spectrum.

Increase of energy efficiency, reliability and durability of technical systems in combination with resource conservation using environmentally friendly water-based lubricants would be an overarching goal in all tribological applications. According to this aim the objective of this work is to investigate and identify new water-based lubricants containing ionic liquids (ILs) to reduce friction and wear. Therefore the tribological behavior of different water-based ionic liquid mixtures, compared with a standard water based cooling lubricant emulsion, was studied using a ball-on-disk test. A three electrode setup was used to analyze the influence of different electric potentials. The results show that friction and wear can be improved by using ionic liquid. In addition, the tribological behavior can be strongly influenced by electric potentials. As tribological mechanism the attraction of cations and the formation of a triboactive layer is assumed, due to charging of the surface.
