论文部分的英文摘要，求英语高手帮忙翻译！不胜感激！！

Anodic oxidation is the traditional surface treatment technology is the use of electrochemical methods, in the corresponding electrolyte and specific process conditions, using metal or metal alloy as anode, stainless steel, iron or nickel as the cathode, through the external current, metal or metal alloy surface layer of stable oxide film process. Generated oxide film can improve the substrate surface corrosion resistance, wear resistance and hardness. Before anodizing, the use of mechanical or compound solution on the surface of the metal and alloy oil and rust removed. According to the different anodizing electrolyte can be divided into different categories, mainly sulfuric acid anodic oxidation, anodic oxidation of oxalic acid, chromic acid anodizing and hard anodizing law, under different acidic conditions can be anodized with different performance membrane. Using natural hair color, electrolysis color coloring or dye impregnation method for coloring anodic oxide film. After coloring the micro pores of the oxide film to be closed, after the closure of the treated surface becomes uniform without holes, the formation of dense oxide film.

Anodic oxidation is a traditional surface treatment technology, is using electrochemical method, in the corresponding electrolyte and special technology condition, with metal or metal alloy anode in stainless steel, iron, such as the cathode or nickel, through the impressed current, in metal or metal alloy surface produces a layer of stable oxidation film process. Generated oxidation film can improve the matrix surface corrosion resistance, abrasion resistance and hardness. Before the anodic oxidation, adopting mechanical method or compounds of metal and alloy surface solution clean oil and rust. Anodic oxidation according to the different electrolyte can be divided into different kinds, basically have sulfuric acid anodic oxidation method, oxalic acid, anodic oxidation method, chromium acid anodic oxidation method and hard anodic oxidation method, different acid process conditions can get different property anodic oxidation film. Using natural hair color method, electrochemical coloring or dyes dipping color of anodic oxidation film method of color. Shading of oxidation film layer after the pore, shall be closed through closed surface become even without holes formed the oxide film, dense.

nodizing is a conventional surface treatment technology is the use of electrochemical methods, in the corresponding electrolyte and specific process conditions, using metal or metal alloy as anode, stainless steel, iron or nickel as the cathode, through the external current, metal or metal alloy surface layer of stable oxide film process. Generated oxide film can improve the substrate surface corrosion resistance, wear resistance and hardness. Before anodizing, the use of mechanical or compound solution on the surface of the metal and alloy oil and rust removed. According to the different anodizing electrolyte can be divided into different categories, mainly sulfuric acid anodic oxidation, anodic oxidation of oxalic acid, chromic acid anodizing and hard anodizing law, under different acidic conditions can be anodized with different performance membrane. Using natural hair color, electrolysis color coloring or dye impregnation method for coloring anodic oxide film. After coloring the micro pores of the oxide film to be closed, after the closure of the treated surface becomes uniform without holes, the formation of dense oxide film.
