【Abstract】 A MICROCOR reluctance probe for rapid measuring corrosion rate, which is based on the determination of metal loss through the measurement of the reluctance change of the probe, is used to study the early stage’s atmospheric corrosion of carbon steel in atmosphere with different relative humidity and composition of saline fog, and thus to realize a quick measurement of metal corrosion in simulate atmospheric conditions. The results showed the higher the relative humidity is, the greater the average corrosion rate is when the composition of saline fog is the same. The influence of concentration of saline fog on the corrosion of 1018 carbon steel is relatively small when relative humidity is low. However, the influence is notable when relative humidity is high.更多还原
