The results showed that the lubricating oils containing combined nanoparticles had good anti-wear and friction reducing effects, and the tribological......
the same structure as bulk Cu and its tribological properties as additives in oil have been evaluated with a T-11 tester. The results show that Cu nanoparticles exhibit good performance in anti-wear......
extreme-pressure( EP), anti-wear(AW) , friction reducion and self-repairing properties. The lubrication and repairing mechanism is inferred that SiO2/ZnO combined nanoparticle is sedimented on the surface of steel, the lower surface film is formed under the high temperature and high pressure. The film possess excellent anti-wear , friction-reducing and repairing properties. 关键词:SiO2; ZnO......
Engineering, Lanzhou University of Technology, Wenzhou 325105, China) Abstract: The tribological properties and the anti-wear and reducing friction mechanism of antimony nanoparticles, which were used... oil were analyzed by SEM and EDS. The results show that the lubricating oil with Sb nanoparticles addition can effectively improve the anti-wear property of lubricating oil. The lubricating oil......
of nanoZrO2 content could effectively reduce the coefficient of friction and enhance the anti-wear ability of PTFEPPS composites. Especially, the best tribological properties of the composites were obtained when the particle content of nano-ZrO2 was 10 vol%, the anti-wear performance of composite is 195 times better than that of the unfilled PTFE-PPS composite. Under different conditions......
that of smaller particles, whereas smaller Mg-α-ZrP particles had better anti-wear properties than that of larger Mg-α-ZrP particles under mild loads. The correlation between the particle size......
:A novel laminated Al2O3/TiC/CaF2-Al2O3/TiC sandwich ceramic composite was fabricated through cold pressing and sintering to achieve better anti-wear.... This process formed a smooth, self-lubricating film, which led to better anti-wear properties. Adhesive wear is the main wear mechanism of Al2O3/TiC/CaF2 layer and abrasive wear is the main wear mechanism......
515063,China) Abstract:The effects of rare earth ferrosilicon on the microstructure and anti-wear properties of laser-clad Fe-based alloy coating were investigated. The composition of Fe,B4C and rare... of lanthanum increases to 1.92%,the clad coating shows the best anti-wear ability,and as the content of lanthanum exceeds 1.92%,the wear weight loss increases quickly. The rare earth ferrosilicon......
