Method of electrolyte - plasma polishing ( also known as method ofа electrolyte Ц impulse or electrolyte - discharge polishing) is based on the phenomena of combined plasma and electrochemical process in the steam-gas thin-gap(jacket) between immersed electrode and electrolyte under influence of high voltage.

аAs result of this treatmentа will be removed few microns of superficial metal and surface obtain mirrorа shine. As well as disappear directional anisotropy which acquire by machine work.

In one operation it will possible to uniteа degreasing,а etching and activation of surface. It is good way for surface preparing before PVD coating ( physicalа vapor deposition). Adhesion between coating and substrate is very strong after this treatment.

The method of electrolyte- plasma polishing has different areas of application such as:

-stainless steel and low carbon steels polishing

-cupper and cupper alloys polishing

-Ti , Mo, Ni and several other metals and alloys polishing.

- machining burrs removing

- featheredge blunting

-pretreatment for futureа electroplating

-Burnish a lot of goods such as bracelet, watch-chain, crockery etc. asа final treatment.

-Polishing someа machine-building ware such as turbine blades, gear wheel etc.

-Polishing of surgical , dental and other medical tools. Polishing ofа bone implants etc.

-Renewing ofа surface after adverse conditions of exploitation, such as corrosion.

 

The main advantage of this method is ecological safety. Acids and alkaline are not in use. As well as another dangerous chemicals in high concentration are not in use. The metal, receding from a surface of workpiece transformed to a solid hydroxide and can be decanted easy.

The process of polishing take a place in water solution of inorganic salt with concentration 4 up to 8 percent. pH of electrolyte = 4 ~ 8.

There are no ions ofа heavy metalsа in scourage.

Not necessary to use highly skilled worker for operate in view of simplicity ofа process.
