Electropolishing
Introduction

The work surface is made use of as the anode to link to the positive post of the DC power supply. Use lead, stainless steel and various other conductive products resistant to electrolyte corrosion as the cathode, and also link to the negative electrode of the DC power supply. The two are involved in the electrolyte (normally based upon sulfuric acid and also phosphoric acid) at a specific distance, and at a specific temperature level, voltage and present thickness (typically less than 1A/cm2), electrify for a certain period of time (usually numerous tens of secs to A couple of mins), the tiny projections on the surface of the workpiece liquify initially, and progressively end up being a smooth as well as shiny surface.



Functions:

1. The polished surface area will certainly not generate a metamorphic layer, no added stress and anxiety, and can get rid of or lower the original stress layer;

2. For Zinc Die Casting , soft products and also thin-walled, complex-shaped, and also small components that are hard to be mechanically brightened Both items can be refined;

3. The polishing time is short, and multiple items can be polished at the same time, as well as the manufacturing efficiency is high;

4. The surface roughness that can be attained by electrolytic sprucing up is related to the original surface roughness, as well as usually can be raised by two levels. However, due to the poor versatility of the electrolyte, brief service life and also strong corrosiveness, the application variety of electrolytic sprucing up is limited. Electrolytic polishing is mostly made use of for metal products and also get rid of small surface area roughness, such as mirrors, stainless-steel tableware, designs, shot needles, springtimes, blades as well as stainless steel tubes.

Advantage

1. the inner and outer colors are consistent, the appeal is long-lasting, and the recesses that can not be thrown by mechanical polishing can also be leveled.

2. High production performance as well as inexpensive.

3. Enhance Stainless steel Fitting of the workpiece surface area.
