摘要The synergism between erosion and corrosion of various types of steels in 10 wt.% H2SO4 + 15 wt.% corundum sand (60 mesh) has been studied by means of a newly designed electrochemically instrumented slurry pot apparatus. The electrochemical measurements under static and rotative condition and the relationship between element distribution and erosion-corrosion (E-C) properties of rapidly and slowly solidified cast alloy D7 (Cr30Ni17Mo2Cu) have been further investigated to illustrate the synergistic mechanism. The results showed that the percentage of the synergism of either carbon steel or stainless steel was very large (32-99%). At a given flow velocity, the total E-C weight loss rate and the weight loss rate due to synergism decreased in the order of X60, AISI321, AISI316L and F5 (Cr25Ni25Mo4Si2Cul). As flow velocity increased from 2.5 to 10 m s(-1), the passive current density of all of stainless steels increased. The breakaway velocity of AISI321 in the test medium is about 7.5 m s(-1). Although the hardness of rapidly solidified as-cast D7 and slowly solidified aged D7 was almost the same, their E-C behaviors differed greatly from each other. The rapid solidification could decrease the differences in the amount of Cr, Mo, Ni, Cu, Si distributed between gamma phase and sigma phase, and the corrosion rate of rapidly solidified as-cast D7 was near zero. As a result, its E-C rate was also low. In contrast, the above mentioned elements are distributed markedly inhomogeneously between gamma phase and sigma phase for slowly solidified aged D7 and its corrosion rate and E-C rate were large.
