Abstract An eco-friendly green corrosion inhibitor Commiphora Mukul was tested for its efficacy to control material loss in 6061 aluminum alloy under collective influence of mechanical erosion and electrochemical a submerged jet impingement rig. Electrochemical techniques were utilized the current investigation which consisted potentiodynamic polarization impedance spectroscopy. The effect temp...

The research focuses on slurry abrasion and erosion of martensitic steels used in the mining agricultural industries. A traditionally constructed pot tester with corundum abrasives form was for wear characterisation. Wear testing performed each specimen 180 h. Every 20 h, pauses were taken to characterise size, weight, hardness, surface roughness. worn zone’s damage progression studied using op...

0.1016/j.nanoen.2 lsevier Ltd. All rig thor. [email protected] Abstract Organic electroactive materials derived from biomasses are promising candidates for next generation rechargeable batteries due to the low cost, sustainability and environmental benignity. Since organic materials have very low electronic conductivity, they are normally synthesized into nano-scale and mixed with conductive carbon...

The aim of this study was to evaluate the effect heat treatment on phase composition, hardness, and abrasion wear resistance hard-anodized layers (HAL) 1011 aluminum alloy. X-ray diffraction analysis revealed Al2O3·3H2O in structure HAL synthesized for 1 h. While heat-treated HAL, oxide phases α-Al2O3(amorphous) γ-Al2O3(amorphous) types were found. Treatment at 400 °C h increased microhardness ...

Filtration is the most cost effective method to purify aluminum. In this paper, filtration experiments have been carried out using both AlF3 slurry coated, and uncoated Al2O3 ceramic foam filter (CFF) to study the removal of both nonmetallic inclusions and impurity elements. The results showed that the 30 ppi CFF removed up to 85% inclusions from aluminum. The contributing mechanisms for the re...

Shear-thickening polishing is a non-traditional finishing method that uses the shear thickening effect by impacting non-Newtonian fluid over machining surface. As result, it forms velocity gradient increases viscosity sharply, producing flexible fixed abrasive tool to remove material. applied for outer surface of rotary workpiece in previous work. The material removal distribution on inner comp...

as a high temperature structural ceramic, cermets exhibit less brittleness than ceramic-ceramic composites or monolithic ceramics owing to the presence of a ductile metal second phase in their microstructure. these cermets can, therefore, be used in applications where the abrasive, creep and thermo-mechanical resistance are required. in the present study, aluminum-alumina cermets with different...

Slurry is widely used in polishing difficult-to-machine materials. However, it accompanied with some issues, such as the agglomeration of abrasives and high disposal cost. Although using fixed abrasive grains instead slurry can solve these problems wear loading grinding stones, which result decrease material removal rate (MRR), also need to be solved. Many researches have been conducted on self...

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...
