On the basis of Y-TZP/Al 2 O 3 nanoceramics, the additive of metal molybdenum was developed to generate Y-TZP/Al 2 O 3 /Mo nanocomposites, which are compounded by nano-sized ZrO 2 –Y 2 O 3 –Al 2 O 3 and micro-sized molybdenum powder as raw material. The objective of this paper was to understand the friction and wear behavior of...
Nano-ZnO was successfully grafted with 2,4-toluenediisocyanate (TDI) and β-aminoethyltrimethoxylsilane (OB551) to avoid the agglomeration of nano-ZnO in composite. The hybrid glass/PTFE fabric composites reinforced with the untreated, OB551 and TDI modified nano-ZnO, respectively, were prepared by dip-coating of the hybrid fabric in a phenolic adhesive resin containing the nanoparticles to be incorporated...
The unfilled and nano-TiO 2 filled hybrid glass/PTFE fabric composites were prepared by dip coating of the hybrid glass/PTFE fabric in a phenolic resin containing the nano-TiO 2 to be incorporated and successively curing. The friction and wear properties of the resulting hybrid glass/PTFE fabric composites sliding against AISI-1045 steel in a pin-on-disc configuration at various condition...
The pure and air-plasma treated Nomex fabric was used to prepare Nomex fabric composites (NFC) by dip-coating in a phenolic resin and the relative mass content of Nomex fabric in the Nomex fabric composites is 65%. The friction coefficient, wear rate and the contact temperature of the Nomex fabric composites were evaluated with a Xuanwu-III high temperature friction and wear tester in a dry sliding...
The carbon fabric composites filled with the particulates of nano-SiO 2 , nano-TiO 2 , and nano-CaCO 3 , respectively, were prepared by dip-coating of the carbon fabric in a phenolic resin containing the particulates to be incorporated and the successive curing. The friction and wear behaviors of the resulting carbon fabric composites sliding against AISI-1045 steel in a pin-on-disc...
Nano Au-TiO 2 composite thin films on Si(100) and glass substrates were successfully prepared with a facile sol-gel process followed by sintering. The morphology and mircostructure of the films were investigated via X-ray diffractometry (XRD), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and scanning electron microscopy (SEM). The Au particles, of diameter 14-22nm...
Nodular cast iron was modified by means of a laser micro-precision treatment. The surface roughness of the treated sample was determined with a profilometer. The friction and wear behavior of the modified specimens sliding against SAE-52100 steel under the lubrication of liquid paraffin (LP) containing various anti-wear and extreme pressure additives was investigated on an Optimol SRV oscillating...
Lanthanum hydroxide nanoparticles modified with succinimide (coded as Succ-nano La) were prepared in laboratory. The tribological behavior of the synthesized nanoparticles blended with zinc dialkyldithiophosphate (ZDDP) as additives in liquid paraffin (LP) to a total concentration of 5wt.% was investigated on a four-ball machine. The surface morphologies and elemental distributions of the worn steel...
The tribological behavior of polyetheretherketone (PEEK) filled with nanometer SiC and polytetrafluoroethylene (PTFE) was studied. The composite specimens with different filler proportions were prepared by compression molding. The effect of PTFE on the friction and wear properties of nanometer SiC filled PEEK was investigated on a block-on-ring machine by running a plain carbon steel (AISI 1045 steel)...
