Heat released in electropolishing of stainless steel

January 8, 2010

The optimum temperature for the process is recommended between 60-90°C. When mixing acids (sulfuric, phosphoric) the temperature rises, this about 70°C (depending on the volumes and compositions), this saves the inmersion heater. But, during the process: Heat is released by resistivity of the solution?
Is that much heat?

Hi, Hiram. Yes, it is a lot of heat. Almost all of the rectifier voltage is absorbed by the resistance of the solution, so the heat is almost Volts x Amps.
