By using a SPS-30 spark plasma sintering pressing sintering furnace, the Cu-50Mo-WC composites were prepared with four different WC content by spark plasma sintering method (SPS). The wear behavior of the Cu-50Mo-WC composite pin against the QCr0. 5 bronze disc was examined on a pin-on-disc tribotester. The worn surface morphologies of the composite were observed by a scanning electron microscope (SEM). The wear mechanism was investigated briefly.The results show that the WC particles improve the hardness and wear resistance of the composites. The main wear mechanism of the composites is of adhesive wear and abrasive wear. When addition of 1% WC content, the optimal comprehensive properties of the composite is obtained.

The microstructure and wear behavior of Cu-TiC composite which prepared by spark plasma sintering (SPS) and mechanical alloying (MA) were discussed in this paper. X-ray diffraction patterns and scanning electronic microscopy (SEM) images indicate that TiC were formed during sintering process. The pin-on-disc wear test was carried. Confocal scanning laser microscope (CFSLM) images indicate that mechanical mixed layer appeared on the worn surface the mechanical mixed layer broken up when normal load reached 200N. The composites displayed excellent wear resistance with 2.38×10−5 mm3/Nm specific wear loss.

Abstract In this present study Al-10% SiC- X % Kaoline (X= 0, 2, 4, 6, 8) HMMC synthesized by spark plasma sintering technique. The fabricated HMMC samples corresponding to maximum compression strength was subjected to tribological investigation under dry, oil and nanofluids lubricating conditions. Nanofluid lubricants were developed by incorporating SiC nanoparticles with weight percentages of 1 wt%, 1.5 wt% and 2 wt% into the soluble oil. The thermal conductivity was found to be increased with increasing the wt % of SiC nanoparticles and the maximum thermal conductivity of 0.771 W/m.K was obtained for the nanofluids with 2 wt% SiC nanofluids. Sliding wear test was conducted on the pin-on-disc tribometer at 40 N load and sliding speed of 1500 r.p.m for a sliding of 180 s. Results reveal that there was a significant effect of the lubricating conditions (dry, oil and nanofluids) on the wear and C.O.F of the HMMC pin surface. The minimum wear of 119 microns and minimum C.O.F of 0.11 was obtained for nanofluid with 2 wt% SiC nanofluid lubricating conditions. SEM analysis of worn surface under dry and soluble oil lubricating conditions reveal the presence of microcracks and delaminations wear. However, worn surface with smooth grooves and absence of microcracks was identified under nanofluid lubricating conditions.

Sintering Method

The four different contents of (Cu/50W)- TiC composites were prepared by spark plasma sintering method. The density, relative density, micro-hardness and conductivity were determined, respectively. The microstructure of the composite was analyzed by SEM. The wear resistance was investigated by a QG-700 atmosphere and high temperature friction and wear tester. The results show that, when the content of TiC is 3%, the optimum comprehensive properties of the (Cu/50W)-3TiC composite are obtained. The density, micuo-hardness and conductivity of the composites are 98.7%, 113HV10 and 61.4%IACS, respectively. The wear mechanisms of the (Cu/50W)- TiC composites are mainly of micro-cutting wear and adhesive wear.

Main Factor

In the present work, the tribological properties of graphene-reinforced Al2O3-SiCw ceramic nanocomposites fabricated by spark plasma sintering were studied against alumina ball. Compared with pure ceramic, the wear resistance of these nanocomposites was approximately two times higher regardless of the applied load. It was confirmed by Raman spectroscopy that the main factor for the improvement of the wear resistance of the Al2O3-SiCw/Graphene materials was related to the formation of protecting tribolayer on worn surfaces, which leads to enough lubrication to reduce both the friction coefficient, and wear rate.
