% of lanthanum could markedly improve the anti-wear and friction-reducing capacities of rapeseed oil.This is attributed to the formation of a complex boundary lubrication film mainly composed... and differential scanning calorimetry.Moreover,the tribological properties of OA/La-TiO2 as lubricant additives in rapeseed oil were evaluated with a four-ball friction and wear tester.The morphology as well......
properties of lithium grease. The morphology and structure of nanocrystals were characterized by means of transmission electron microscopy(TEM) and X-ray diffraction(XRD), respectively. Friction and wear tests were conducted on the friction and wear tester.Results show that the lithium grease with addition of nanometer-CeO2 has much better friction-reducing and anti-wear performance than that of base......

film (3.73×10-8 A/cm2). The synthesized composite film has good anti-wear and anti-corrosion properties and the growth mechanism of nanocomposite film is also discussed.Key words:Ti6Al4V alloy; anodic...Microstructure and abrasive wear behaviour of anodizing composite films containing SiC nanoparticles on Ti6Al4V alloyLI Song-mei(李松梅), YU Xiu-mei(郁秀梅), LIU Jian-hua(刘建华), YU Mei(于美), WU Liang(吴量......
matrix powder is a viable engineering material in practical anti-corrosion and anti-wear coating applications. Key words: Fe-based metallic glass; coating; corrosion resistance; HVOF spraying 1... resistance was investigated, compared with 304L stainless steel, in a practical application as anti-corrosive and/or anti-wear material in corrosive environments. 2 Experimental Using the powder mixtures......
of 0.32-0.38 and good anti-wear properties at 400 ℃. Keywords: HVOF spray processing; submicron tungsten disulphide; microstructure; self-lubricating composite coating anti-wear properties at high working temperature, as shown in Fig.8. With testing time prolonging, mass loss of coating at room temperature has a quick increasing tendency......
of the composite coating reaches 1 050. Compared with Ni-P coating, the composite coating reveals much better friction and anti-wear performance, and the friction coefficient and wear rate are only.... The transfer film can avoid the direct contact between the composite coating and the steel ball, keep sliding well lubricated and thus very low friction coefficient and wear rate are available.Key words......
. The results show that the wear resistances of graphite-containing composite are much better than those of the matrix under the test conditions. The anti-wear ability of magnesium alloy composite is improved... done on graphite particle reinforced metal matrix composites which exhibit low friction, low wear rate, and excellent anti-seizing properties. In this viewpoint, an attempt is made to prepare AZ91......
