If one of the surfaces which are in touch is rough and hard, it chips the other surface due to relative motion or touching forces. The wear is called two-body abrasive wear. If there are free abrasive particles between the two bodies, the wear is called three-body abrasive wear. The free abrasive particles may be external material dust or the remains of chipping. Usually, the wear starts as a t...

The presence of oxygen in the environment in which a steel sliding system operates will promote a mild form of wear with wear debris consisting mainly of iron oxides. Of the oxidation-dominated mechanisms, mild-oxidational wear (the prefix describes the extent of oxidation and not the wear rate) has been most extensively investigated. In this paper, examples will be used to show that the wear-m...

A model of the flank wear of cutting tools is developed by using linear control theory. The flank wear is assumed to consist of a mechanically activated and a thermally activated component. The wear process is mathematically treated as a feedback process, whereby the progressive wear raises the cutting forces and temperature thereby increasing the thermally activated wear-rate, and contributes ...

In this research, a glassy carbon electrode was coated with a thin layer of multi-walled carbon nanotubes in the presence of the surfactant and subsequently was electro-polymerized with Poly-L-arginine (P-L-Arg). The prepared electrode was used as an effective sensor for the quantitative detection of Rutin (Ru). The fabricated electrode exhibited good electrochemical performance with low electr...

Incoloy 825 alloy is often used in calorifiers, propeller shafts, and tank vehicles owing to the improved resistance aqueous corrosion. The electrochemical micromachining process can be utilized machine such an engineering material higher precision lower tool wear. In present study, investigation was performed enhance of creating micro-holes using silver-coated copper electrodes. sodium nitrate...

Wear experiments have shown that when the applied normal stress exceeds a critical value, a transition occurs from the regime of mild wear to that of adhesive wear. As a result, the wear rate of particle-reinforced aluminium composites increases by a hundred-fold. Based on dislocation and delamination theories, a criterion is proposed for determining the critical transition load, and a quantita...

This study investigated the oxidation of ascorbic acid (Vitamin C) using a platinum nanoparticle electrode coated with an iodine monolayer, called a modified electrode. The electrode were grown using the cyclic voltammetry technique and the electrochemical measurements were taken using the cyclic voltammetry and chronoamperometric technique. In the case of platinum nanoparticle electrode modifi...

Experimental analysis of tool wear in alumina micromachining by multi-tip Electrochemical Discharge Machining (ECDM) technique is reported. Multi-tip electrodes having a tip size 300 µm and length 10 mm are created stainless steel wire-EDM. Experiments conducted at different feed rates, i.e., 0.25 µm/s, 0.50 0.75 µm/s. Tool 3 × array electrode categorized into three zones, outer-most tip, outer...
