摘要: Abstract La-doped Mg/Al layered double hydroxide (LDH) was synthesized and intercalated by sodium dodecyl sulfate. Friction properties of LDHs as lubricant additives were evaluated in four-ball friction air compressor test. The results showed that Mg/Al/La-LDH prepared with La/Al molar ratio 0.1. interlayer spacing expanded from 7.662 to 25.663 A after intercalation. product exhibited better tribological property than its precursor the tests. improved performance attributed a reduction between laminates, good dispersion nanoparticles medium an effective tribofilm formed on contact surfaces.
