A type of new environmentally friendly lube additive---boron-nitrogen modified soybean oil was synthesized and characterized by infrared spectrum. Its effect on the friction and wear behavior of steel-steel and steel-aluminum alloy systems were investigated with a four-ball machine and an Optimol SRV friction and wear tester respectively. The morphographies of the worn surfaces were analyzed by means of scanning electron microscopy (SEM).The worn surfaces of the 2024Al alloy block were analyzed by means of X-ray photoelectron spectroscopy (XPS).The results show that the type of modified soybean oil as additives can obviously decrease the wear rate and friction coefficient of steel pair and steel-aluminum frictional pair. Its lubrication mechanism is inferred that a high strength adsorption film and/or tribochemistry reaction film on the worn surface of the Al alloy due the carrier effect of a long chain soybean oil, high reaction activities of nitrogen, electron-deficient of boron and their synergisms.

The friction and wear behavior of polyetheretherketone (PEEK) composites was investigated, which are reinforced with nanometer Al2O3 or nanometer TiO2 and blended with polytetrafluoroethylene (PTFE) in a fixed weight fraction of 10% and are prepared by heat compression moulding. The studies emphasized particularly on the nanometer Al2O3 filled PEEK composites. The tests were performed on a pin-on-disc test apparatus with a PEEK composite pin sliding against AISI 1020 carbon steel disc under dry friction conditions and were all carried out at room temperature. The worn surfaces of the PEEK composites were examined by scanning electron microscopy (SEM). Results indicated that the above PEEK composites exhibited lower friction coefficient and wear rate in comparison with the mixture of PEEK with PTFE. The SEM micrographs of the worn surfaces indicated that the scratched and ploughed marks appeared on the wear scar of PEEK filled with PTFE, while the scuffing on the worn surfaces of nanometer Al2O3/PTFE/PEEK was obviously abated. The optimal content of nanometer Al2O3 in the filled PEEK composite should be recommended as 6.5 wt %. The friction behavior of the nanometer TiO2/PTFE/PEEK composites was far better than that of the nanometer Al2O3/PTFE/PEEK composites under the same test conditions and with the same content of nanometer compounds, which was perhaps due to much more strong synergistic effect between nanometer TiO2 and PTFE than that between nanometer Al2O3 and PTFE.

A type of new environmentally friendly lube additive----boron-nitrogen containing modified soybean oil was synthesized and characterized by infrared spectrum. Its tribological properties in rapeseed oil were tested on the four balls tester. The morphographies and tribochemical species of the worn surfaces were analyzed by means of Scanning Electron Microscope (SEM) and X--ray Photoelectron Spectroscope (XPS). The results show that the type of modified soybean oil as additives can obviously increase the load-carrying capacity 、anti-wear and friction-reducing abilities of rapeseed oil. Its lubrication mechanism is inferred that a high strength adsorption film and/or tribochemistry reaction film on the worn surface of the Al alloy due the carrier effect of a long chain rapeseed oil, high reaction activities of nitrogen, electron-deficient of boron and their synergisms.

Ni-P-β-SiC was prepared using different granularity β-SiC and rolling electroless plating technology. The test results show that β-SiC particles in composite coating are uniform, and the thickness and hardness of composite coating are 17~25μm and 520~620HV, respectively. At the same time, the friction and wear behavior of Ni-P-β-SiC composition coating have been studied. The results show that the wear weight loss decrease and the friction coefficient increase with the increase of β-SiC granularity.
