“…The addition of MoS 2 particles facilitates heat dissipation which in turn resists surface melting of polymer. 44 Now as the load is increased from 30 N to 40 N in PC2, the presence of ploughed furrows increases with increase in fibre breakage due to shearing, filler de-bonding and matrix tearing (Figure 5e and f). The addition of 10% betel nut powder shows smoother surface than that of neat PC/ABS matrix.…”

In this study, the composites with incorporation betel nut powder at three levels (10, 18 and 25%) in Polycarbonate (PC) and Acrylonitrile Butadiene Styrene (ABS) matrices having Kevlar Fibres (KF) and Molybdenum Disulphide (MoS2) nano particles in fixed amounts are looked into for their tribological characteristics. The effect of hardness, surface roughness and density was evaluated. FTIR and X-ray diffraction (XRD) studies have been carried out to identify the phases. The effects of load on the slide wear loss and coefficient of friction of the composites were determined using Pin on Disc set up. The wear test pertaining to the betel nut bearing (BNP) composites were compared with those of betel nut free ones i.e. PC/ABS/KF/MoS2. The results revealed that with increase in load, the wear loss increases. Further with increase in betel nut powder concentration from 10% to 25% there is a decrease in wear loss as well as coefficient of friction. The surface morphology of the worn surface were examined using Scanning Electron Microscopy (SEM) which revealed higher plastic deformation, debris formation and furrowing in BNP free systems compared to betel nut bearing ones.

The effect of compatibilization on the reciprocating frictional behavior of a polyamide 66 (PA66)/ultra-high molecular weight polyethylene (UHMWPE) blend was investigated. The influence of the amount of added maleic anhydride-grafted polyethylene (MAH-g-HDPE) on the phase morphology, compatibility, and viscoelasticity was explored using scanning electric microscopy (SEM), dynamic mechanical analysis (DMA), and capillary rheometry. In addition, the effect of MAH-g-HDPE on the reciprocating friction and wear performance of the PA66/UHMWPE blend was tested. The worn surface, transfer film, and wear debris were analyzed using SEM, X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FTIR). The results showed that the maleic anhydride groups in the MAH-g-HDPE improved the compatibility of PA66 and UHMWPE, and the addition of MAH-g-HDPE enhanced the interface bonding strength and lowered the polar difference between PA and UHMWPE. Therefore, the improved compatibility enhanced the wear resistance of the blend. During reciprocating sliding, UHMWPE transferred to the counterface prior to PA66 for the incompatible blend. The addition of MAH-g-HDPE promoted the adhesion and transfer of PA66 to the counterface.

Polyimide-based solid lubricating films were prepared by simple and efficient spin coating proceeding. Several composite lubricating films were obtained by changing the composition and contents of inorganic solid lubricants in organic binder. The structure, physical phase, and performance of the synthesised lubricating films were characterised by using X-ray diffraction, scanning electron microscope, fourier transform infrared spectrometry, thermo gravimetric analyzer, and nano-indentation methods. And the friction coefficients of these composite lubricating films were measured by pin-on-disk structural tribometer. The results showed that all kinds of lubricating films had good adhesion strength. Compared with the pure polyimide film, the composite lubricating films exhibited better thermal and mechanical properties. These composite lubricating films, with MoS 2 and graphite as solid lubricants, could effectively reduce the friction coefficient of polyimide film. Moreover, the friction coefficient of the composite lubricating film filled with the above two kinds of lubricant decreased to the minimum 0.141.
