Electropolishing
Introduction

The work surface is utilized as the anode to attach to the favorable post of the DC power supply. Lost Wax Casting Use lead, stainless steel as well as various other conductive materials immune to electrolyte corrosion as the cathode, and attach to the negative electrode of the DC power supply. The two are engaged in the electrolyte (typically based on sulfuric acid and phosphoric acid) at a specific range, and also at a particular temperature, voltage and present density (normally less than 1A/cm2), energize for a particular period of time (typically a number of tens of seconds to A few mins), the tiny outcroppings externally of the work surface dissolve first, as well as progressively end up being a smooth and glossy surface area.



Features:

1. The sleek surface will certainly not create a metamorphic layer, no added stress and anxiety, and also can eliminate or decrease the original stress and anxiety layer;

2. For difficult materials, soft products as well as thin-walled, complex-shaped, as well as little parts that are difficult to be mechanically polished Both products can be processed;

3. The polishing time is short, as well as numerous pieces can be polished at the same time, and also the manufacturing effectiveness is high;

4. The surface roughness that can be achieved by electrolytic sprucing up is related to the initial surface roughness, and normally can be enhanced by two levels. Nevertheless, as a result of the bad versatility of the electrolyte, brief life span as well as strong corrosiveness, the application series of electrolytic polishing is restricted. air blow gun Electrolytic polishing is mainly used for steel products and also get rid of little surface area roughness, such as mirrors, stainless-steel tableware, designs, injection needles, springs, blades and stainless steel tubes.

Benefit

1. the inner and external shades are consistent, the appeal is durable, as well as the recesses that can not be tossed by mechanical polishing can likewise be leveled.

2. High manufacturing performance and inexpensive.

3. Boost the corrosion resistance of the workpiece surface area.
