Electrochemical treatment

Elektropol-R is the first company in Poland to have used the unique process of internal electropolishing of acid-resistant pipes.

Besides galvanisation (plating), electropolishing is undoubtly the most advanced technique of electrochemical processing of metals. The main purpose of electropolishing is fine smoothing of the detail's surface but in practice this goes together with deep anodal passivation resulting in excellent corrosion resistance of steel. In case of chromium-nickel steel alloys, electropolishing treatment has additional positive effect: concentation of chromium on the surface layer increases significantly (iron and nickel are being etched with a faster rate), so the surface becomes much harder. 

Object before process -> Object after etching, ready for electropolishing -> Object after electropolishing

Electropolishing is a very fine process - etching is only limited to these fragments of the surface what are elevated above the average in a microscopic scale while macroscopic structure remains completly unaffected. Consequently, all fine details and contours remain unaltered while the surface gains aesthetic glossy look. Such a surface provides very easy cleaning what is essential for food, pharmaceutical or electronical industry for instance. Because actual hardness of steel has no impact on the process of electropolishing, the cost of electropolishing treatment does not depend on surface hardness reached on preceding steps of the processing chain - unlikely to traditional mechanical methods of steel polishing. The chemical composition of media used for electropolishing and appropriate control of physicochemical parameters of the process are critical for its efficiency and final results. No wonder, know-how is a secret and fundamental asset for companies involved in electropolishing besides machinery and people. Exceptional experience, proprietary know-how, skilfull engineering and high motivation stand behind ELEKTROPOL-R. You may trust the quality of our service!
