The results show that the erosion corrosion rates of 65Mn and 316L in single liquid phase and liquid/solid two–phase flow increase with increase of media’s temperature and decrease of theoretic velocity of flow under the condition of same flow distance. Their mass loss rates caused by synergistic effect between erosion and corrosion in 20% H2SO4 and 20% H2SO4 + 20 g/L sand  (50℃, 1.88 m/s) were respectively 80.35 and 127.21 g·m−2·h−1 for 65Mn and 5.25 and 17.22 g·m−2·h−1 for 316L. The mechanism of the erosion corrosion in two–phase flow were respectively even corrosion + slightly plough–cutting for 65Mn and slightly select corrosion + slightly plastic deformation for 316L. The erosion corrosion resistances of 65Mn and 316L were improved significantly by electroless plating Ni–P. The higher the media’s temperature and velocity of flow, the more significant the effect.
