as compared with that lubricated with neat rapeseed oil. The enhanced anti-wear and friction-reducing abilities of rapeseed oil by SRO in the lubrication of magnesium alloy against steel were ascribed... words: anti-wear; friction-reducing; magnesium alloy-steel tribomate; sulfuration modified rapeseed oil 1 Introduction In recent decades, magnesium alloys are finding increasing use as structural......
Friction and wear performances of borates and lanthanum chloride in water陈波水,方建华,王九,李嘉,娄方摘 要:The antiwear and friction-reducing performances of sodium... chloride increased extreme pressure, antiwear and friction-reducing capacities of water to a certain extent, of which potassium borate was the best candidate. Combination of lanthanum chloride with sodium......
) Abstract:The antiwear and friction-reducing performances of sodium borate, potassium borate and lanthanum chloride in water were evaluated on a four-ball friction tester. The topographies, element...). The results indicated that sodium borate, potassium borate and lanthanum chloride increased extreme pressure, antiwear and friction-reducing capacities of water to a certain extent, of which potassium borate......
, Fe2C and Fe3N. Under dry sliding condition, the friction-reducing of sulphurized surface is good, but its function time can''t last very long. The nitrocarbonided+sulphurized surface can greatly improve the wear-resistance and the friction-reducing of CrMoCu alloy cast iron, and its integrated friction and wear properties are better than plain and sulphurized surfaces''. 关键词:ion nitrocarburizing......
of up to 500 nm. In the meantime, OA/LaBO3·H2O nanorods can obviously improve the anti-wear and friction-reducing capacities of rapeseed oil, and the optimal anti-wear and friction-reducing properties... improve the friction-reducing ability of RP. However, RP containing LaBO3·H2O provides higher friction coefficients than RP. This might be attributed to the poor solubility of LaBO3·H2O in RP. Fig......
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......
% 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......
