Dispersion and their tribological properties of molybdenum nanoparticles with different particle sizes as additive in lubricating oil

Using silane coupling agent KH-570 as the surface modifier-molybdenum nanoparticles with various particle sizes were prepared by mechanical ball milling method. The molybdenum nanoparticles with different particle sizes were added into 900SN base oil to form the experimental lubricating oils. The di...
