Detta projekt genomfördes på uppdrag av PTC, Production Technical Centrum for Sciences, med fokus på att utforska elektropolering av PH13-8, en specifik legering av rostfritt stål av AK Steel Corporation från 1989. Målet var att identifiera processparametrar för optimal elektropolering. Genom användning av Gamry Reference 3000 potentiostaten och Framework-programmet utfördes elektropoleringen med 'Potentiostatic experiment'. Experimenten upprepades över ett hundratal gånger med varierade tidsintervall för att utvärdera möjliga utfall. Processparametrarna, som importerades från polariseringsexperimenten, styrdes av antingen 'Galvanostatic experiment' eller 'Potentiostatic experiment', beroende på Gamry potentiostatens spänningsregleringskapacitet. Efter elektropoleringen genomfördes noggranna steg av sköljning, torkning och visuell samt mikroskopisk kontroll av proverna. De erhållna resultaten avslöjade distinkta skillnader mellan olika experiment, där vissa resulterade i uttalad gropfrätning och i vissa fall var gropfrätningen helt eliminerad. Optimala parametrar för elektropolering av PH13-8 har tagits fram under projektets gång

This project was conducted on behalf of PTC, Production Technical Centrum for Sciences, with a focus on exploring the electropolishing of PH13-8, a specific alloy of stainless steel developed by AK Steel Corporation in 1989. The objective was to identify process parameters for optimal electropolishing. Utilizing the Gamry Reference 3000 potentiostat and the Framework program, electropolishing was carried out through 'Potentiostatic experiment'. The experiments were repeated over a hundred times with varying time intervals to assess potential outcomes. The process parameters, imported from the polarization experiments, were controlled either by 'Galvanostatic experiment' or 'Potentiostatic experiment', depending on the voltage regulation capacity of the Gamry potentiostat. Following electropolishing, meticulous steps of rinsing, drying, and visual as well as microscopic examination of the samples were conducted. The obtained results revealed distinct differences between various experiments, with some resulting in pronounced pitting corrosion, while in certain cases, pitting corrosion was completely eliminated. Optimal parameters for electropolishing PH13-8 were derived throughout the project duration.
