Aluminium alloy composites have been extensively investigated for use in tribo-contact applications, however little detailed literature exists on the sub-surface microstructural evolution as a result of lubricated sliding wear. In this study two un-reinforced alloys (2124 & 5056) and identical alloy composites, reinforced with 15vol.% MoSi2 intermetallic particles were produced by a powder meta...

In this work, the dielectrophoretic force (F(DEP)) response of Aluminium Microelectrode Arrays with tapered profile is investigated through experimental measurements and numerical simulations. A standard CMOS processing technique with a step for the formation of a tapered profile resist is implemented in the fabrication of Tapered Aluminium Microelectrode Arrays (TAMA). The F(DEP) is investigat...

investigation of aluminium uptake by human erythrocytes was the major aim of this study. packed red blood cells were incubated in earle's medium (ph 7.4) containing varying concentrations of aluminium (0-160 /lg/j) as aik(so.), and aluminium content of the cells were determined using flameless atomic absorption. there was significant increase in aluminium content of the cells. addition of ...

Original scientific paper The paper deals with the effect of roughness, residual stresses and pitting corrosion on different shot peened (SP) ENAW 7075 aluminium alloy in different states. Suitable residual stress profile increases the applicability and life cycle of mechanical parts, treated by shot peening. Pitting corrosion has a major influence on aging of structural elements made of high s...

Long-term consumption of water containing excessive fluoride can lead to fluorosis of the teeth and bones. Electrocoagulation (EC) is an electrochemical technique, in which a variety of unwanted dissolved particles and suspended matter can be effectively removed from an aqueous solution by electrolysis. Continuous flow experiments with monopolar aluminium electrodes for fluoride removal were un...

Use of conventional flexible polymeric mould materials yields to longer solidification time of (wax/plastic) patterns in soft tooling process, thereby reducing the rapidity of the process to a great extent, which is not desirable in present competitive market. In this work, approach of particle-reinforcement with mould materials is introduced to reduce the cycle time of Soft tooling process and...

1. Rat gut perfusion studies in vivo at pH 4, 6 or 8 using aluminium chloride or equimolar aluminium chloride and sodium citrate showed that elevated plasma aluminium concentrations were associated with aluminium solubility in the perfusion. Elevated plasma aluminium levels and soluble aluminium in the perfusate occurred with perfusion of equimolar aluminium chloride and sodium citrate at all t...

Aluminium powders are used in a wide range from propelling rockets to improving personal hygiene. More popular industrial applications include manufacture of silver metallic pigments, paints, inks, plastics, packaging, textiles and aerospace industry. As thick film pastes used in the manufacture of silicon solar cells, and as reducing agent and sources of heat, used in alumina thermic and exoth...

In this paper, behaviour of Al2O3 in aluminium matrix composites is reviewed for its properties and applications. addition, many metal composite fabrication processes are also elaborated. the present days high demand because superior properties. Its still on rise widespread use automotive industries, aerospace industries marine industries. The method matrix-based a deciding factor resultant Des...

The technique known as Equal Channel Angular Pressing (ECAP) has gained prominence a transformational method for improving the mechanical characteristics of metals and alloys by subjecting them to intense plastic deformation. This study explores significant difficulties that arise when using on Aluminium 2024-Beryl Metal Matrix Composites (2024-BMMCs), providing detailed analysis complex intera...
