Study of corrosion behavior of steel cans after filling and factors affecting polarization resistance

The corrosion behavior of steel cans after filling was analyzed, and polarization resistance developed to predict the shelf life of filled cans. The factors influencing the measurement of polarization resistance, including temperature, pressure, volume of beverage in can, orientation of polarization, scanning rate, and stability of corrosion potential, were studied. It was concluded that temperature and pressure affected polarization resistance to a greater extent, that the influence of volume of beverage in can on polarization resistance varied with polarization resistance itself, and that the effect of orientation of polarization, scanning rate and stability of corrosion potential on polarization resistance was weak, during the measurement of polarization resistance.
