Due to it`s strength, corrosion resistance, low weight and biocompatibility, titanium is increasingly used for high-quality, functional workpieces. The application ranges from medical technology to apparatus engineering, vehicle and aircraft construction to sports equipment and jewelry.
The electropolishing of titanium and titanium alloys provides surfaces of the highest quality in terms of purity, cleanability, corrosion resistance and passivity. Electropolished surfaces are free of burrs, scales and particles. Their high gloss makes them attractive for decorative applications.
The electropolishing process POLIGRAT E 398 is suitable for workpieces made from titanium and titanium alloys and Nitinol only suitable to a limited extend. The surface becomes bright, burr-free, clean and smooth on a microscopic scale. Depending on the material, roughness values can be achieved down to the range of <0.1 μm Ra.
POLIGRAT E 398 removes damaged material surfaces without mechanical, thermal and chemical stress and develops the pure properties of the material.
The very high removal rate allows short processing times (usually 0.2 to 5 min), so that single-part treatment can be carried out quickly and efficiently.
POLIGRAT E 398 is supplied ready for use and applied in immersion bathing. The electrolyte is specially developed for single-part treatment. The workpieces can be processed on a jig
The electrolyte is anhydrous and highly hygroscopic. Before introducing to the electropolishing bath, the parts must be dried. Pay attention to a complete drying.
After electropolishing the surface must be rinsed clean. The rinsing water is strongly acidic and contains the dissolved metal. It is to be treated and disposed of according to the statutory laws and regulations.
