Stainless Steel Electrolytic Tube

Principle: Electrolytic polishing under certain conditions, the dissolution rate of metal anode is greater than the lysate leave the surface of the anode to the speed of diffusion in the electrolyte, the lysate then accumulated in the electrode surface, form a layer of adhesive film, the film of viscous resistance is larger than the electrolyte, and can dissolve in the electrolyte, it is uneven distribution along the surface of the anode, The thickness of the micro mucosa at the micro convex surface is smaller than that at the concave, which leads to the smaller resistance at the convex surface, resulting in the current concentration. Compared with the micro concave, the current density at the micro convex surface is larger, and the potential is increased, so that the oxygen is easy to precipitate, which is conducive to the dissolution and diffusion of the mucosa and speeds up the dissolution of the metal at the micro convex area. With the extension of electrolytic polishing time, the micro-convex part on the surface of the anode is gradually flattened, so that the whole surface becomes smooth and bright.Advantages:The inner and outer color is consistent, the luster is lasting, and the concave place that can not be thrown by mechanical polishing can also be leveled. Increasing the surface corrosion resistance of the workpiece can enhance the surface corrosion resistance by more than 4-5 times. (In the electrolytic polishing at the same time in the product workpiece surface will form a phosphate film similar to the passivation film, so that the product surface is not easy to react with oxygen and water in the air, chloride ions, etc.) the surface of the electrolytically polished product is bright and smooth, and the dirt is not easy to adhere, so that the surface adsorption force of the workpiece is weaker.
