Dependence of Milling Time on Electrochemical Properties of Nano Si Electrodes Prepared by Ball-Milling

Journal of Nanoscience and Nanotechnology, 2011
Morphology, crystallinity and electrochemical properties of Si powders fabricated by a mechanical milling process with milling time of 6-40 h were investigated by means of FESEM, XRD, Raman, TEM and cell test. Average size of Si powders was reduced to sub-micrometer scale after 10 h-milling and 40 nm-Si powders could be obtained at 48 h-milling.

Generation of Stepped Profiles on Ti6Al4V by Electrochemical Milling

Journal of The Institution of Engineers (India): Series C, 2019
Generation of accurate complex-shaped products on various high-strength temperature-resistant (HSTR) alloys such as titanium and nickel alloys is a key feature for many kinds of machine parts widely used in diverse industries starting from biomedical to defence industries. Being free of tool wear, thermal stresses and residual stresses, electrochemical

Factors influencing the kinetics of electrochemical reactions in milling

Journal of Materials Science, 2004
Input of mechanical energy at a high rate can drive a system and induce phase transformations and chemical reactions away from equilibrium. The evolution of such a change depends on both thermodynamic as well as kinetic factors. Besides the microstructural changes like attainment of nanostructure, which alters the overall free energy, the high rate of ...

Experimental and numerical investigations in electro-chemical milling

CIRP Journal of Manufacturing Science and Technology, 2016
This paper presents experimental and numerical investigations into electro-chemical (EC) milling of simple features such as slots and pockets. Preliminary experimental investigations into the machining of a slot enabled appropriate process parameters to be selected; these were then used to machine a simple square pocket and finally a pocket with a ...

Electrochemical Milling and Faceting: Size Reduction and Catalytic Activation of Palladium Nanoparticles

Angewandte Chemie International Edition, 2012
Improved performance through milling: A method for enhancing the catalytic activity of supported metal nanoparticles is reported. This method enhances the activity for the ethanol electro-oxidation of a supported palladium catalyst. The much higher catalytic performance is ascribed to the increased electrochemically active surface area as well as the ...

Experimental Investigations on C-263 Alloy by Electrochemical Milling

The International Journal of Advanced Manufacturing Technology, 2019
Electrochemical machining has great potential of machining of any HSTR metals due to its various advantages like free of tool wear, thermal, and residual stresses. The process of electrochemical milling is similar to conventional electrochemical machining (ECM).

Electrochemical properties of LiFePO4 prepared via ball-milling

Journal of Power Sources, 2009
Abstract LiFePO4 cathode materials with distinct particle sizes were prepared by a planetary ball-milling method. The effects of particle size on the morphology, thermal stability and electrochemical performance of LiFePO4 cathode materials were investigated.

Fabrication of nanosized metallic copper by electrochemical milling process

Journal of Materials Science, 2007
Using a copper oxide powder of micrometer size as the starting electrode material in CuO/Li cells, copper oxide (CuO) can be electrochemically reduced into metal particles of smaller sizes in a controllable way. A novel electrochemical milling (ECM) method is developed for a “top–down” synthesis of nanometer-scaled metal particles.

An electrochemical study of corrosive wear of phosphate grinding mill

Journal of Applied Electrochemistry, 2006
The corrosion of metallic grinding media and mill liner is a very significant problem, particularly under acidic conditions as encountered in the Florida phosphate fertilizer industry. Approximately half of grinding media wear results from corrosion or oxidation dissolution of metal surfaces.
