Today, carbide is a major tool in manufacturing tool materials.
Because of these feature, compared with the traditional mechanical contact passivation , electrochemical - mechanical reducing the workpiece and grinding tools and materials for direct losses.
But for carbide materials, the surface after electrolysis will produce a layer of dense blue passivation film, and other more obvious white oxidation also producted , and in order to remove the oxide film, increase the cleaning step of mechanical passivation after electrochemical , in which the mechanical passivation round metallic composite materials using appropriate.
At the time, in fact, the total absence of heat and rough force, it’s surface have not distortion, and no burr and organization of materials aberrations.

Introduction
Although carbonaceous materials are one of the most commonly used commercial lithium-ion battery (LIBs) anode materials [1], the solid diffusion coefficient of lithium ions (Li+) in graphite electrode materials is low, which leads to high diffusion resistance of Li+ during charge-discharge processes and limits their application in high-performance LIBs.
Carbon nanowires and carbon nanotube arrays are typically one dimensional carbonaceous heterogeneous materials.
Characterization of physical properties of materials.
This novel preparation method can be widely used to prepare other kinds of polymer nanowire materials.
