【文摘】: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 scar 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.【正題名】: Synthesis and tribological properties of ferrous octoxyborate as antiwearand friction-reducing additive of lubricating oil

【文摘】:An oil-soluble compound containing ferrous iron and boron-ferrousoctoxyborate was synthesized.The antiwear and friction-reducing properties of the compound as alubricating oil additive were evaluated using a four-ball and a block-on-ring tribotester.Results indicated that both the wear resistance and the load-carrying capacity of a 500 SN base oil were improved and its friction coefficient was decreased by the additive.The wear scar, alter being cleaned using an ultrasonic bath in ligroin and in distilled water, was characterized with SEM and XPS.Diboron trioxide, FeB and Fe{sub}2B were all found to have been deposited on the wear-scar surface.It was this deposition that provided the oil with excellent antiwear and friction-reducingproperties.【正題名】: Preparation of magnesium borate succinimide and its characteristics as alubricating oil additive

【文摘】:Succinimide has for a long time been widely used for ashless dispersants in engine lubricating oils.However, this kind of dispersant does not have particularly good antioxidant, antifriction, antiwear or acid neutralisation properties.In this paper, a method is suggested for modifying succinimide so as to obtain improved antioxidant, acid neutralisation, antifriction, and antiwear properties.Magnesium borate cannot be dissolved in mineral lubricating oil.In the presence of succinimide, however, it will exist in a lubricating oil in the form of acolloid or complex.Therefore, in the present work, magnesium oxide, boric acid, and water were mixed together with succinimide.In the reaction process, some of the magnesium borate formed in situ will be surrounded by succinimide, forming stable colloids;the remainder will react with thesuccinimide, forming well distributed complexes in the lubricating oil.The presence of water is very important for this process.At least four moles of water are needed for one mole of magnesium borate.The resulting material has been evaluated as a lubricating oil additive.The experiments have shown that this kind of material possesses good antioxidant, acid neutralisation, antifriction,and antiwear properties, apparently due to the introduction of magnesium borate.The introduction of the magliesium borate does not influence the good dispersant properties of the succinimide.【正題名】: A study of N and S heterocyclic compound as a potential lubricating oil additive
