GPA INNOVATIVE S.L. (also known from now as GPA) was founded in Barcelona in 2013, legally constituted as STEROS GPA Innovative S.L., in order to provide solutions to various strategic challenges in the field of product design and the development of industrial applications. Among the eight different business lines, the main one is known as DLyte®. DLyte® is based on the patented DryLyte® Technology, the world's first dry-electropolishing process and it is suitable for the most common industrial metals, alloys and composite materials. It automates, simplifies and standardizes the post-processing of these set of materials, improving the surface finish obtained with traditional polishing processes. Within 918 machines on the market, 521 are used in the dental industry (representing the 56.75% of the total business). Therefore, to improve the polishing surface quality of dental alloys is a must for the company. Within this context, the very first aim of this Master thesis is to determine which DryLyte® electrolyte and/or electrical parameters are more suitable for polishing dental materials and in particular CoCr RPDs (chrome cobalt - Removable Partial Dentures). For that, an exhaustive electrolyte characterization and a surface analysis of the workpieces before and after being polished with this technology is realized. Also, another goal is to find a compromise between the electrical parameters and the better surface quality finish of RPDs and, last but not least, to ascertain if CoCr RPDs can be successfully polished under direct current (DC).
