Abstract

Alkaline electrolysis is considered to be a basic technique for hydrogen production. Many researchers have investigated the alkaline electrolysis in order to promote the electrochemical reaction. In most of the metal corrosion will occurs via electrochemical reaction at the interface of the metal and an electrolyte solution. While the corrosion will occur on metal but the different metal have different rate of corrosion depend on the composition of the metal. This paper studies about the corrosion rate of Stainless Steel type 316 with different thickness into potassium hydroxide (KOH) electrolyte alkaline (pH14). The aim for this investigation is to obtain the corrosion rate of stainless steel plate in an alkaline electrolyte and to study the corrosion rate of stainless steel with different thickness. The stainless steel will be soaked into Potassium Hydroxide because of Potassium Hydroxide is a highly corrosive chemical. The investigation covered the effects of current, solution concentration, and thickness of stainless steel on the characteristics of alkaline electrolysis. The study was carried out under atmospheric pressure using stainless steel electrodes. It will involve the flow process in electrolysis. Besides that, this project also needs the rolling mill machine to reduce the thickness of stainless steel. In this experiment, the plate of stainless steel was cut into pieces in size 5 cm x 5 cm and the range of thickness is 0.2 mm to 0.5 mm. The result shows that by reducing the plate thickness of stainless steel will increase the corrosion rate. In conclusion, the corrosion rate for thickness 0.2 mm is higher than 0.5 mm and thickness 0.5 mm longer good for low corrosion rate.
