Electropolishing
Introduction

The work surface is made use of as the anode to connect to the favorable pole of the DC power supply. Use lead, stainless-steel as well as other conductive products resistant to electrolyte deterioration as the cathode, as well as connect to the adverse electrode of the DC power supply. The two are immersed in the electrolyte (generally based upon sulfuric acid as well as phosphoric acid) at a specific range, as well as at a specific temperature, voltage and also current thickness (normally less than 1A/cm2), amaze for a certain amount of time (generally numerous tens of seconds to A few minutes), the little protrusions externally of the work surface liquify first, as well as slowly end up being a smooth as well as shiny surface.



Functions:

1. The refined surface will not generate a metamorphic layer, no additional anxiety, and can remove or decrease the original tension layer;

2. For difficult products, soft materials and also thin-walled, complex-shaped, and also small parts that are hard to be mechanically brightened Both products can be processed;

3. The polishing time is short, and numerous pieces can be polished at the same time, and also the production efficiency is high;

4. The surface area roughness that can be attained by electrolytic polishing is connected to the original surface roughness, and normally can be boosted by two degrees. Nonetheless, Valve Seat to the inadequate versatility of the electrolyte, short life span and solid corrosiveness, the application range of electrolytic polishing is restricted. Steel Forging sprucing up is mostly used for steel products and get rid of little surface area roughness, such as mirrors, stainless-steel tableware, decors, shot needles, springs, blades and stainless steel tubes.

Advantage

1. the internal and outer colors are consistent, the gloss is long-lasting, and the recesses that can not be tossed by mechanical polishing can also be leveled.

2. High manufacturing effectiveness and also affordable.

3. Boost the corrosion resistance of the workpiece surface.
