The present paper reports abrasive wear behaviour of copper matrix composites reinforced with silicon carbide and silica particles. Copper – SiC (12%) and Copper-SiO2 (9%) composites were prepared by powder metallurgical technique. Metallography, image analysis and hardness studies were carried out on copper composites. The abrasive wear experiments were carried out using pin on disc apparatus. The effect of sliding distance and load was studied on Copper – SiC (12%) and Copper-SiO2 (9%) composites. The abrasive wear volume loss increased with sliding distance in both the composites although the magnitude of increase was different in each case. Copper – SiC (12%) composites exhibited relatively better abrasion resistance as compared to and Copper-SiO2 (9%) composites. The abraded surfaces were observed under scanning electron microscope to study the morphology of abraded surfaces and operating wear mechanism. The analysis of wear debris particles was also carried out to substantiate the findings of the investigation.

AbstractIn this study, the effects of SiC reinforcement volume fractions on hardness, porosity and abrasive wear behaviour were examined in Al 2014-SiC (<92.3 μm) reinforced metal matrix composites (MMCs) of 3%, 6% and 12% reinforcement–volume (R-V) ratios produced by melt-stirring. Abrasive wear tests were carried out by 320 mesh Al

Three body abrasive wear behaviour of Polyamide 66 and Polypropylene (PA66/PP) blends in different weight percentages of 95/5, 90/10, 85/15, 80/20, 75/25 and 70/30 are investigated. The experiments were carried out as per ASTM G65 by using rubber wheel abrasion tester (RWAT). The tests were conducted for a load of 50 and 75 N at a sliding velocity of 2.5 m/s with an abrading distance of 500, 1000 and 1500 m using fine abrasive dry sand particles as third body. The experimental results revealed that the wear volume and specific wear rate are the functions of load, abrading distance and composition of blend. It was observed from the experimentation that the lower loading of PP into blend decreases the wear resistance. The effective wear resistance starts from higher loading of PP (30 wt.%) in the blend. The abrasive sand particles and their size played a major role in determining the wear characteristics of PA66/PP blends. Substantiate amount of rubber wheel wear contributes to the development of wear resistance. The worn surfaces are studied by using Scanning Electron Microscope (SEM) photographs.

Abrasive Wear Behaviour

The development of lightweight materials has drawn more attention in the last decade in the field of household, construction and automobile sectors in place of conventional materials. New environmental policies are forcing researchers to design and develop new lightweight materials that are environmentally friendly. The development of bio-composites in place of synthetic fibre composites is one of the solutions for this. This article deals with an experimental investigation of tribological properties of orange peel particulate (a biowaste) epoxy composites. The hand layup technique is used to fabricate the composite material by varying the filler loading from 0 to 30% with a variation of 10%. The abrasive wear behaviour of the fabricated composite was analysed by using a pin-on-disc set up under dry sliding conditions with varying loads at different sliding velocities. Based on the experiments, it is observed that the wear behaviour of neat epoxy material has enhanced significantly with the addition of the orange peel particulates as filler materials. The characterisation of orange peel particulates was done using energy-dispersive X-ray spectroscopy, X-ray diffraction and Fourier transform infrared spectroscopy. The surface morphology study of the worn surface with respect to wear mechanism indicates plastic deformation and development of cracks at optimum filler concentration (20 wt%). With a higher filler concentration (30 wt%), brittle failure of the composite was noticed.

Wear by slurry abrasion is very expansive problem that must be taken into consideration while selecting the material for the transportation of slurry through pipeline. Abrasive wear generally occurs when abrasive slurries come in contact with the industrial engineering components or slurry transporting pipes. The abrasive particles carried by slurries eventually remove the material from the encountering surfaces which results in the early failure of the component in service. In present investigation an attempt is made to study the effect of load, slurry concentration, sliding distance on the abrasive wear behaviour of mild steel. The slurry abrasion experiments were carried out using slurry abrasion test apparatus with silica sand slurry. The findings of the present investigation indicate that slurry abrasion volume increased with slurry concentration, load and sliding distance, although the magnitude of increase was different in each case. The SEM observation of worn out surfaces revealed micro ploughing and micro cutting as wear mechanisms.
