Electropolishing
Overview
The workpiece is utilized as the anode to attach to the favorable post of the DC power supply. Use lead, stainless steel as well as other conductive materials resistant to electrolyte deterioration as the cathode, and connect to the unfavorable electrode of the DC power supply. The two are involved in the electrolyte (typically based on sulfuric acid and also phosphoric acid) at a certain distance, and also at a certain temperature level, voltage and also present thickness (generally less than 1A/cm2), electrify for a certain period of time (usually a number of 10s of secs to A few minutes), the small projections externally of the workpiece dissolve first, and slowly come to be a smooth and glossy surface area.
Attributes:
1. The sleek surface area will not produce a metamorphic layer, no additional stress and anxiety, and also can eliminate or decrease the initial tension layer;
2. For tough materials, soft products as well as thin-walled, complex-shaped, as well as little parts that are tough to be mechanically polished Both products can be processed;

Valve Seat
3. The polishing time is short, and multiple items can be brightened at the same time, as well as the manufacturing performance is high;
4. The surface roughness that can be accomplished by electrolytic polishing is associated with the original surface roughness, and also normally can be increased by 2 degrees. However, as a result of the poor flexibility of the electrolyte, short service life and strong corrosiveness, the application series of electrolytic sprucing up is limited. Electrolytic polishing is mostly made use of for steel items as well as get rid of tiny surface roughness, such as mirrors, stainless-steel tableware, decors, shot needles, springtimes, blades as well as stainless-steel tubes.

Benefit
1. the internal and also external colors correspond, the appeal is durable, and also the recesses that can not be thrown by mechanical polishing can likewise be leveled.
2. High manufacturing efficiency and inexpensive.
3. Increase the deterioration resistance of the workpiece surface area.
