●Principle of electrolytic polishing
The principle of electrolytic polishing (EP for short) is to connect the workpiece to the anode and place it in the electrolyte to apply direct current, and use electrolysis to dissolve and remove the metal and impurities on the surface of the workpiece, so that the surface of the workpiece is smooth, clean, flawless, and bright. , It can also improve the corrosion resistance of the surface, which can be said to be the best surface brightening method.
●Electropolishing characteristics
When the passivation layer stainless steel material is electrolytically polished, the voltage, current, acid composition, temperature and polishing time can be adjusted appropriately based on the principle of electrochemistry to control the thickness of the cadmium oxide film on the processed surface, so that the stainless steel tube can reach the maximum Good corrosion resistance.
The process of high cleanliness electropolishing is to remove the most surface of the workpiece, so the magazine layer, oxide layer, residual stress layer, etc. on the surface will be removed. After processing, a very flat surface can be obtained, and no dirt can be contained. The depression of the workpiece, so that the surface of the workpiece can reach a high degree of cleanliness when in use.
Suitable for processing thin workpieces and special shapes. During the electrolytic polishing process, the workpiece is soaked in the electrolyte, so it is not subject to any stress, there will be no surface processing deterioration layer and surface residual stress, but it can be dissolved. Remove the parts in the previous process The stress layer on the surface due to machining. Therefore, electrolytic polishing is very suitable for processing thin workpieces and special-shaped workpieces, and for small workpieces, it can be performed in large quantities at a time to reduce processing time.
