摘要: Abstract The tribological behavior of polyphenylene sulfide (PPS) filled with inorganic nano particles was studied. fillers investigated were TiO 2 , ZnO, CuO and SiC whose sizes varied from 30 to 50 nm. polymer composites compression molded varying proportions these fillers. Wear friction tests performed in a pin-on-disk configuration at sliding speed 1.0 m/s, nominal pressure 0.65 MPa, counterface roughness 0.10 μm Ra. composite pins slid against hardened tool steel counterfaces. transfer films the materials formed on counterfaces during studied by optical microscopy X-ray photoelectron spectroscopy (XPS) adhesion between film measured terms peel strength. It found that wear rate PPS decreased when used as but increased ZnO optimum resistance obtained 2 vol.% or . These had coefficients lower than unfilled PPS. is explained topography observed strength studies. There good correlation film–counterface bond resistance.
