摘要：

Erosion corrosion behavior of a carbon steel and a stainless steel was studied by electrochemical measurements in jet-in-slit sand erosion testing. The test was conducted under the conditions of slurry flow rates lower than 5 m/s, pH range 1. 5-7. 0 and alumina particles of 4 multiplied by 10** minus **5 m diameter. The erosion corrosion rate is evaluated in terms of the corrosion rate obtained by electrochemical measurement and the erosion rate. The rate of the carbon steels is 15-300 times higher than that of the stainless steel. Under cathodic protection, the rate decreases, resulting in about the same rate as the stainless steel.
