- W149623699 abstract "Electropolishing is the surface finishing/polishing technique electro chemicallyand sandblasting is the surface treatment method for improving the mechanicalproperties of the material. In this study, both methods are used in stainless steel AISI316L. The purpose of this study is to analyze the effect of sandblasting on the changesin microstructure and the hardness of stainless steel AISI 316L and the combinationeffect of sandblasting and electropolishing to surface roughness, hardness, andcorrosion resistance in stainless steel AISI 316L.Surface roughness of specimens were tested before and after the sandblastingand the electropolishing process. The tool used was sandblasting machine with aworking pressure of 5-7 kg/cm2 with a duration of 10 minutes. The sand used was silicasand with a size of 500-800 I¼m. The tools used in the electropolishing process is the DCpower supply with a maximum output of 2x100A. Anode and cathode material wasstainless steel AISI 316L. Electrolyte solution consisted of 96% mass fraction ofsulfuric acid (H2SO4) and 85% mass fraction of phosphoric acid (H3PO4) with a ratioof 1:1. The parameters used in the electropolish process was voltage of electrical,distance of electrodes and duration of electropolishing process.The results show that increasing the voltage, decreasing the distance, andincreasing the duration in the process of electropolishing decrease the surface roughnessup to more than 28 times, increase the hardness up to 69% and corrosion resistance upto 37%." @default.
