07/22: ELECTROCHEMICAL SMOOTHING OF METALS USING ION-CONDUCTING SOLIDS IN WEAKLY CONDUCTIVE SOLUTIONS

Whitepaper Electropolishing

For applications in dental technology, it is very important to achieve a homogeneous, smooth surface without affecting the delicate components, e.g. side clasps of dental parts. Conventional polishing baths for smoothing cobalt-chrome dental parts can smooth the surface, but the result can be very uneven, de-pending on the shape of the workpiece. As an alternative, weakly conducting electrolytes with ion-exchanging solid particles based on styrene copolymers and sulfonated divinylbenzene have been available on the market for several years. This article draws a direct comparison between both methods, in terms of the electropolishing result and the surface quality achieved, using optical microscopy and roughness measurements.
