How to protect power feed contacts from hurting when wire cut processing? I believe many people want to know that. Because power feed contacts are very easy to wear in processing, protect power feed contacts from hurting in wire cut processing effectively can save a lot of cost of company. In the electrolyte, power feed contacts disposed anode, under the influence of external electric current, in the production process of an oxide film formed on the surface is called the anodic oxidation film is an anodic oxide film produced by the electrochemical conversion coating or electrochemical natural oxide film and the oxide film is different from the structure of the oxide film is stacked cells, each cell of a hexagonal column, the top end of an arc-shaped pores possessed hexagram cut surface. oxide film with two-layer structure. Close matrix metal and a thin layer of dense, pure AL2O3 film thickness of 0.01 ~ 0.05μm, and high hardness, the layer is a barrier layer; outer surface of a porous oxide film, the crystal water AL2O3 composition with low hardness .
The main component of the electrolyte by electrochemical oxidation can be divided into: sulfuric acid anodizing, oxalic acid anodizing, chromic acid anodizing; press oxide film functions can be divided into: wear layers, corrosion coatings, bonding layer, insulation layer, porcelain and decorative oxide film. Additionally the surface treatment of aluminum plating ways can be used to improve the hardness of the first copper foiling then hard chrome plating, decorative chrome plating decoration can, in addition can also be colored anodic oxidation treatment.
