ApNano Materials Inc., a cleantech company and provider of nanotechnology-based products, on April 23 announced that a new test conducted at the FZG Gear Research Centre of the Technical University of Munich, Germany, shows that ApNano Material’s nanotechnology-based lubricant NanoLub significantly decreases damaging wear pits on gear teeth. The test was done on oil that was formulated with a NanoLub additive.
“The test proves that NanoLub significantly enhances automotive and industrial gear oils, improving pitting resistance,” said
Oil blended with NanoLub was evaluated at the FZG Gear Research Centre according to a recognized international test procedure for investigating the influence of lubricating oil (especially the quality of additives in these oils) on the wear and damage of gears.
In such conditions, indications of damage appear as micro-pits or small holes on the surface of the gears. The test can differentiate between oils of varying quality and thus facilitates identifying a high quality lubricant additive that provides adequate resistance to pitting and wear.
The test at the FZG Gear Research Centre follows other tests done by Dr. Adrian Oila of Newcastle University, England, on gears with heavy-duty gear oil that was blended with NanoLub powder. No wear damage to the steel lubricated with the NanoLub oil could be observed with an optical microscope, while significant wear was observed for the reference oil. The presence of a beneficial tribofilm was detected on the gears lubricated with the NanoLub formulation. The tribofilm continues to lubricate the moving parts also in cases where the oil supply is interrupted.
NanoLub, ApNano’s proprietary nanotechnology-based lubricant, is based on nanosized particles of tungsten disulfide (WS2) that have a structure of nested spheres, called inorganic fullerenes, whose lubrication mechanism includes the layers slipping off under loads to form an adherent film that reduces friction and wear. These new nano spheres have first been synthesized by
In addition, NanoLub “wraps” the moving parts with a lubricating thin film called tribofilm and continues to lubricate normally for a long time, as an “uninterruptable lubrication source” during severe oil leakages. In addition to the significant reduction in wear, NanoLub also contributes to a considerable reduction in the friction between moving parts resulting in a smoother ignition in case of “cold start”, increased power, and to an improved fuel economy with lower emission of greenhouse effect gases.
