The morphology and microstructure of PA46 wear debris and transfer film were studied by using scanning electron microscopy (SEM), Fourier transform infrared spectrometer (FT-IR) and X-ray diffractometer (XRD) for understanding the physical and chemical changes of PA46 caused by friction. An acid-eroding method was used to peel the transfer film from the mated steel ring surface. It was found that...
PA46/HDPE polyblends with different component ratios and the same content of compatibilizer HDPE-g-MAH were prepared to investigate the main influence factors for the tribological properties of the polyblends. Scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and X-ray diffraction (XRD) were used for investigating the phase structure and crystalline characteristics of the...
The friction properties of poly(acrylic acid) (PAAc) hydrogel have been studied under low loads using a ball-on-plate friction tester. And the influences of atmospheres, load, water contents of the polymers and its surface morph have been investigated. It is found that the friction coefficient of hydrogels is obviously lower in water than in air. The friction coefficient of PAAc hydrogel decreases...
