Dry wear behaviour of AA6061 Aluminum alloy, reinforcement with fine particulates of Silicon Carbide (25μm) and Aluminium oxide(40μm) are existed and discussed here in research paper. The reinforcement of Al alloy hybrid metal matrix composite (HMMCs) with 5-25% vol. fractions of Silicon Carbide and Aluminium oxide particles are produced by stir casting methodology and test specimen were prepared by using them . The dry sliding behaviour of these hybrid metal matrix composite specimen and that of Al6061 unreinforced alloy at ambient temperature was examined by using pin-on-disk Wear Testing Machine over a weight range of 29.43N-49.05N (3-5 kgf) along a sliding distance of 1413m at constant sliding speed of 1.57m/s. The result confirms that, the reinforced metal matrix with Silicon Carbide and Aluminium oxide particles up to a vol. fraction of 25% reduces the wear in μm at ambient temperature. Increases the volume fraction of the reinforcement decreases the wear in μm. The result also displays that the wear in μm of test specimen increase with increase in load and sliding distance.
Natural fibre composites today are replacing synthetic fibre composites due to superior properties of natural fibres such as low density, high specific strength and modulus, relative no abrasiveness, ease of fibre surface modification, and wide availability .Drilling is often required to facilitate the assembly of the parts to get the final product. however, drilling composite materials present a number of problems such as delamination associated with the characteristics of the material and with the used cutting parameters .The present investigation is an attempt to study the factors and combination of factors that influence the delamination of drilled unidirectional jute fibre reinforced composites using taguchi, signal to noise ratio, Anova analysis and to achieve the conditions for minimum delamination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
