| With increasing of load, speed, temperature and other parameters for modern machinery and equipment, original friction-reducing additive and anti-wear additive can not meet its own performance requirements. Since the 1990s, with depth study of nanometer material and Nanotechnology by people, discovered that unique structure of certain nanometer materials enable it to have the special tribological performance, and nanometer lubricant additives that are made by these nanoparticles can greatly improve anti-friction and anti-wear performance for lubricants, and find new ways of settlement for the problems that been not able to solve for a long time in the area of lubricants. Nanoparticles material has unique surface and volume effect, with it into the lubricant, the lubricant will have both good anti-wear and extreme pressure performance and restoration function. To develop nanoparticles lubricant additives can improve the effect of lubricant commendably and upgrade the integration performance of lubricant. Nanoparticles tech and multi-function are definitely a direction of development on lubricant additives.By using Four-ball test machine the anti-wear and extreme pressure performance of the ceramics nanoparticles additives,the compatibility of the ceramics nanoparticles additives and other kinds of additives,the anti-wear and extreme pressure properties of complex allocation for the ceramics nanoparticles additives and various additives ,were investigated. The uniform design of experiments is firstly used for arranging multi-level and multi-factor experiments. The stepwise technique is adopted to put forward the regression equation. The compatibility among additives are studied by a series of tests. The results show that the anti-wear and extreme pressure performance of the basic oil that contain the ceramics nanoparticles additives are better. |
