Potassium formate aqueous solutions have been considered as heat transfer fluids or coolants for electronics cooling applications. Electrochemical corrosion tests were performed on high purity silicon specimens in 42% potassium formate solutions between 298 K and 348 K, with a magnetic stirring rate of 400 RPM. Open circuit potentials were recorded, and corrosion rates were calculated from Tafel scan curves tested at a scan rate of 0.4 mV/s, and the influence of temperature was assessed. The effect of a corrosion inhibitor package was also investigated.
