as base oil, along with some structure improver, antioxidant and anti-wear extreme pressure additive, lithium complex grease was developed. The dropping point of the grease is 331℃, friction factor...]. From 1970s, lithium complex grease developed rapidly, and lithium complex grease with dibasic acid, stearinic acid and ortho-hydroxybenzoic are called new generation lithium grease[4, 5]. In China......
properties of lithium grease. The morphology and structure of nanocrystals were characterized by means of transmission electron microscopy(TEM) and X-ray diffraction(XRD), respectively. Friction and wear tests were conducted on the friction and wear tester.Results show that the lithium grease with addition of nanometer-CeO2 has much better friction-reducing and anti-wear performance than that of base......

that, the decline of impedance can be ascribed to the complex reaction between the lithium electrodes and the electrolyte to form SEI film. After the relatively stable SEI film was formed, the value of Rint... J. Cent. South Univ.

Article ID: 1003-6326(2005)03-0626-05 Inhibition effects of PMA/SbBr3 complex inhibitor on copper and copper-nickel alloy in LiBr solutions HU Xian-qi(扈显琦), LIANG Cheng-hao(梁成浩... and copper-nickel alloy are 67.48μm/a and 38.14μm/a, respectively. Since both anodic and cathodic electrochemical reactions can be inhibited, PMA/SbBr3 belongs to complex inhibitor. PMA has the effect......

considered as the most efficient processes. However, the low lithium grade (~3% Li2O in concentrates) resulted in a much more complex process to economically extract Li than that from spodumene, which has... J. Cent. South Univ.
