...Khalida Akhtar; Saniya Yousafzai Calcium carbonate powder comprising uniform nanoparticles of novel morphology was synthesized under extensively optimized trial parameters. The as-prepared ultrafine rod shape CaCO 3 particles after characterizations were used as an antiwear/antifriction additive...

...Jiang Zhao; Xinlei Gao; Tao Chen; Tingting Wang; Yang Li The structural parameters of 23 ionic liquids were calculated by the Hartree–Fock ab initio method. The relationship between the antiwear properties of ionic liquids dissolved in dimethyl sulfoxide and the structural parameters of the ionic...

...Ze Song; Tao Chen; Tingting Wang; Zhan Wang; Xinlei Gao The antiwear properties of ionic liquids (ILs) as lubricant additives were studied with polyethylene glycol (PEG) used as the lubricant base oil. The quantum parameters of the ILs were calculated using a Hartree–Fock ab initio method...

.... % CCC and commercial CaCO 3 additives, respectively. The significantly enhanced antiwear and antifriction performance of the optimum CCC-CLG in comparison with the blank and commercial CaCO 3 -additized CLG was quite encouraging, and extensive studies in a real machine-operating environment...

... of the BPNN-QSTR model show that the extent of polar groups cannot be too large in the molecule to achieve good antiwear performance; and the polar groups with a high degree of relative concentrated charge are favorable for antiwear. A low degree of molecular hydrophobicity of lubricant base oil is beneficial...

... of CNTs as an additive on lithium grease were evaluated with a four ball tester. The results show that the grease with CNTs exhibit good performance in antiwear (AW) and decrease the wear scare diameter (WSD) about 63%, decrease friction reduction about 81.5%, and increase the extreme pressure (EP...
