In the present study effect of SiC content and sliding speed on the wear behaviour of aluminium alloy and composite was studied using pin-on-disc apparatus against EN32 steel counterface. These tests were conducted at varying SiC particles in 10, 15 and 25. wt.% and sliding speeds of 0.52, 1.72, 3.35, 4.18 and 5.23. m/s for a constant sliding distance of 5000. m. The results revealed that as the SiC content increases the wear rate and temperature decreases, but reverse trend can be observed for coefficient of friction. All these facts can be discussed on the basis of prevailing wear mechanism. © 2010 Elsevier Ltd. Source

In this study, a new phenomenological material flow model is established and validated to describe the dynamic deformation behavior of Al-2024 alloy with respect to the wide range of strain rate, strain, and temperature. When compared to the JC Model and Modified JC Model, it is found to give a more accurate and precise estimate of the experimental output. The main advantageous feature of the proposed model over many other models is that it requires the experimental data results of compression test only and at the same time it retraces the experimental outcome with higher efficiency. © 2012 Elsevier B.V.

One of the advantages reported in Al-base alloy particulate composites is its improved sliding wear properties over its base alloy by several investigators. Much of the improvement depends on the experimental conditions, alloy composition as on the particulate size, shape and distribution in the matrix. The present paper will make an attempt to assess the improvement in sliding wear properties attained in a few Aluminium base alloys with different size, quantity and distribution of SiC-particulates and bring out the efficacy of making composites if any in the different alloy systems over other methods of property improvement like homogenisation, secondary processing, etc. In some cases remarkable improvements have been achieved, such as the composites have sustained much harsher conditions whereas the base alloy has seized at much milder conditions; whereas in other alloy systems the improvement is only comparable to that obtained by secondary processing. Properties attained on homogenisation, extrusion and making composites would be compared with the base alloys. In this paper an attempt will be made to draw a line as to the conditions under which composites can been used to make engineering products where improved sliding wear resistance is demanded and where more prevalent methods like ageing could serve the purpose. © 2009 Elsevier Ltd.

This investigation pertains to the influence of some test parameters like applied load, sliding speed and test environment on the sliding wear behaviour of a grey cast iron. Properties studied were wear rate, frictional heating and friction coefficient in dry and oil lubricated conditions. The wear response of the samples has been discussed in terms of specific characteristics like load bearing, lubricating and cracking tendency of different microconstituents of the cast iron. Examination of wear surfaces, subsurface regions and debris particles has also been carried out to understand the operating wear mechanisms and further substantiate the observed response of the samples. © 2011 Elsevier Ltd.

Both sides of a graphene oxide (ai-GO) layer are decorated with functional groups. For the first time it is demonstrated that an effective reduction of ai-GO to graphene can be performed, even if the reducing agent can access only one side of ai-GO. A general reduction mechanism is proposed. © the Partner Organisations 2014. Source
