Evaluación del comportamiento sinergístico de la erosión-corrosión sobre un acero AISI-SAE 1020 en un medio multifásico salmuera-CO2-arena por técnicas electroquímicas

the weight loss caused by the phenomenon of erosion-corrosion is not equal to the amount of weight loss of erosion and corrosion when two processes act separately; the synergy between the processes contributes as much as 50% in some cases as it is shown in this research. the tests were conducted in a cell of erosion-corrosion where the dynamic was controlled by the rotating cylinder electrode at speeds between 1.000 and 3.000 rpm, the particle size of sio2 ranging between 50 and 150 μm, and their concentration between 10 and 30% which defined two regimes of erosion-corrosion: at low rotations, the contribution of the corrosion controlled the degradation phenomenon, and at high rotation, the erosion controlled the degradation of the system.
