月桂酸插层改性Ni/Al-NO3-LDHs及其对摩擦性能的影响
Ni/Al-NO3-LDHs Intercalated with Dodecanoic Acid and its Tribological Characteristics
摘要
Abstract
The nickel aluminum layered double hydroxides（Ni/Al-NO3-LDHs） intercalated with dodecanoic acids were prepared via coprecipitation by an anion exchange method.The obtained compounds were characterized by X-ray diffraction,Fourier transform infrared spectroscopy,thermogravimetry-differential scanning calorimetry,scanning electron microscopy and specific surface area analysis,respectively.The tribological performance in the base oil was investigated by a four-ball wear machine and a gear testing machine.The results indicate that the shape of the crystal obtained before the intercalation appears hexagonal flake with the crystal size of 40 nm and the specific surface area of 96.57 m2/g.After the intercalation,the channel height of Ni/Al-NO3-LDHs increased,but the specific surface area decreased.The Ni/Al-NO3-LDHs and its products intercalated with dodecanoic acid could reduce the friction coefficient,wear scar diameter,lubrication medium temperature and drive motor power as well.关键词
