Research progress of nano lubricating additives

Lubricating Oil Additives

1.1 Lubrication (Rizvi, 2009) The principle of supporting a sliding load on a friction reducing film is known as lubrication (Ludema, 1996). The substance of which the film is composed is a lubricant, and to apply it is to lubricate. These are not new concepts, nor, in their essence, particularly involved ones. Farmers lubricated the axles of their ox carts with animal fat centuries ago. But mo...

The Effect of Nano-Additives on the Hydration Resistance of Materials Synthesized From the MgO-CaO System (RESEARCH NOTE)

In this study, the effect of variety of Nano- additives doping on the hydration resistance of the MgO-CaO system was investigated. Samples were prepared from calcined dolomite and magnesite. Nano-additives that contained cations with various valences (trivalent and tetravalent) used as  a dopant. The bulk density, apparent porosity and hydration resitance were studied and evaluated. Also, phase...

Separation & Identification of Organic Compounds in Lubricating Oil Additives Using TLC &GC-MS

Thin layer chromatography (TLC) and Gas Chromatography-Mass Spectrometry (GC-MS) techniques are proposed for qualitative analysis of lubricating oil additives (Hitec 2915). The additives were dissolved in heptanes, extracted with mixed solvents heptane: acetonitrile (3:2) and spotted on TLC paper. The best combination solvents as developer for TLC analysis were carbon tetrachloride: heptanes (9...

Fullerene derivatives as nano-additives in polymer composites

Metallic Nano-particles as Fuel Additives in Air-breathing Combustion

Title: METALLIC NANO-PARTICLES AS FUEL ADDITIVES IN AIR-BREATHING COMBUSTION Gregory Young, Doctor of Philosophy, 2007 Directed By: Associate Professor, Dr. Kenneth H. Yu, Department of Aerospace Engineering For volume limited propulsion systems, the use of metals as fuel additives offers to increase performance by increasing the volumetric energy stored in the fuel. Highspeed airbreathing comb...
