Experimental Study of Wear Rate Coefficient of Aluminium Hybrid Composites Ma...AM Publications
In current decade, demand in material characteristics like light weight, superior strength to weight ratio, improved surface properties and enhanced wear resistance for complex engineering applications like automobile, aerospace and nuclear are researcher’s interest. However, performance of hybrid composites depends on right combination of reinforcements. Silicon carbide, silicon nitride, boron nitride and titanium carbide are few reinforcements available at present. In this work, Al356 is reinforced with SiC and B4C to enhance the mechanical properties, surface hardness and wear resistance. This hybrid composite is prepared by stir casting technique and the morphology of composite is studied using optical microscope to investigate the dispersion of reinforcements. In the present study, the wear and friction characteristics of hybrid composites are investigated using pin on disc dry wear tests by varying the load and speed and the results are tabulated for load vs mass loss, load vs wear rate and load vs wear coefficient. The results report that wear rate of hybrid composites are lower than that of binary composites. Mechanical properties, surface hardness and wear characteristics of aluminium hybrid composites are compared with that of aluminium binary composites available at present.
Aluminium Matrix Composites (AMC’s) are widely used in aerospace, automotive,
structural and marine applications due to their high strength to weight ratio, corrosion
resistance. In AMC one of constituent is aluminium or its alloy which forms a network
called as matrix phase and other constituent is embedded in matrix made of harder material
generally ceramic or non metallic material called as reinforcement. Various processing
techniques are available for manufacturing of AMC’s. Stir casting is one of the economical
and extensively used methods to enhance attractive properties of AMC’s. This paper
presents an overview of stir casing process, process parameter and preparation of AMC
using aluminium alloy as matrix phase and alumina (Al2O3) as reinforcement by varying
their proportion.

Preliminary study of on cladding process on gray cast iron substrateeSAT Journals
Abstract Cladding, also called as hardfacing or surfacing, is a deposition process with a purpose of improving the properties of the substrate accomplished either using laser beam or arc as the heat source for the process. Filler material used in the process is deposited layer-by-layer until covering required thickness before being machined to achieve the final dimension. Gas metal arc welding is seen as the best method for accomplishing the cladding operation as the alternative for laser cladding in term of operation cost. The process parameters of gas metal arc welding are discussed on in the aspect of the cladding process. Grey cast iron with its inherent brittleness characteristic is difficult to be weld cladded because the thermal cycle of the cladding process can cause the material to crack. It is understood that the coarse graphite flake structure that gives the lack of ductility characteristic to the material and cause the material to crack when suffer the stress occur during the temperature drop of the process. Nickel based filler material is seen as the best choice to be used for the deposition process because of its ability to precipitate carbon in its free form of graphite and prevent the migration of carbon from cast iron substrate thus avoiding the formation of hard carbide phase. The addition of tungsten carbide in the matrix of nickel base alloy gives the filler material good hardness and wear resistant properties. This paper serves as the preliminary study to get an insight into the understanding of cladding process on cast iron as the substrate before performing the experiment of the cladding operation. Keywords: Cladding, Hardfacing, Cast Iron, Nickel Based Alloy
Effect of Nano-Magnesium Oxide and Graphite Particles on Mechanical Propertie...Premier Publishers
The main objective of this present work is to determine the densification, hardness and impact strength behavior on LM09 alloy reinforced with graphite and magnesium oxide nano-particles. LM09 is lighter metal as compared to other engineering metals/alloys except magnesium and beryllium. In this research stir casting process was used to fabricate hybrid LM09 nano-composite. The composites were prepared by varying the proportion of reinforcements such as 1.2 wt.% graphite (constant) and 1.5-3.5 wt. % magnesium oxide. Densities of alloy and nano-composites were determined by using the rule of mixture and Archimedes principles. Composite with 1.2 wt. % graphite and 2.5 wt. % magnesium oxide have 95.75% of relative density. Theoretical and actual densities are closer so that the cast composites were produced with less porosity. The mechanical properties of nano-composite such as hardness and impact strength was measured and clearly show that the LM09 alloy is enhanced through the reinforcement of nano-particles. Hybrid nano-composite reinforced with 2.5 wt. % magnesium oxide dominates the hardness as compared to other composites (1.5 and 3.5 wt. % magnesium oxide) The increase in reinforcement particles enhances the impact strength proportionally. The present finding concludes that LM09 hybrid composite having 1.2 wt. % graphite and 2.5 wt. % magnesium oxide can be used for engineering applications.

STUDIES OF MICROSTRUCTURE, MECHANICAL AND TRIBOLOGICAL PROPERTIES OF AL-2Cu-2...dbpublications
The aim is to study the mechanical, tribological property and wear behavior of Al7068 alloy/alumina composite with various weight fractions (3%, 5%, 7%) were prepared by stir casting method. In addition, Al7068 were cast for comparison purposes. Microstructure, hardness and tensile properties of these composites were evaluated and compared with as-cast alloy and the composites. In addition, tribological properties of these composites were also evaluated. The wear and mechanical properties of composites improve with increasing the weight fraction of Alumina and then decreases gradually. This study provides an alternative way to enhance the tribological behavior of Al7068 alloy/Alumina composite. The study also highlights the different contribution of different input process parameters (like: composition of Al7068 alloy/Alumina and particle size of reinforcement material) on wear properties of Al7068 alloy/Alumina MMCs.
Fabrication, charecterization and development of high damping materials for n...eSAT Journals
Abstract Aluminum matrix composites are early inventions during 60’s. Presently these are used as railroad equipment and aerospace components. Their application has shown no further growth during the last decade due to lack of toughness. The non-compatibility between the matrix and the reinforcement and lack of good interface among these led to the reduced ductility levels. The limited solubility leads to the alloy formation passing solid solution strengthening while the un dissolved particles help achieving dispersion strengthening. Instead of taking ceramic particulates as reinforcements, metallic reinforcements were dispersed in aluminium matrix. Damping characteristics were calculated for the alloy and composites. Suitable heat treatment enhances the properties of the composite further. The expected mechanical properties will be higher than the regular alloys, which can be useful for various components in naval applications where high damping is required. Keywords: Dispersion Strengthening, Damping.
