Nanoparticle magnesium borate with a particle size of about 10 nm was prepared using ethanol supercritical fluid drying technique and was characterized with TEM, XRD and X-ray small angle scattering. Tribological properties of the nanoparticle magnesium borate, using as lubricating oil additive, were evaluated using a four-ball and a block-on-ring tribotester. The wear sear was characterized with SEM and XPS. Results indicate that the wear resistance and load carrying capacity of the 500 SN base oil were improved and the friction coefficient of the oil was decreased by the additive. FeB were formed on sliding surface. (C) 2002 Published by Elsevier Science B.V.
