Effect of Alloying Elements on the Corrosion Wear Behaviors of Low Chromium Cast Iron

Abstract:

The effect of alloying elements on the corrosion wear behaviors of low chromium cast iron in slurry with different ions was studied by self-made three-body corrosion wear tester. The results show that the corrosion wear resistance of low chromium cast iron was decreased with the increase of concentration of Cu²⁺ ion or SO₄2- ion in slurry. The corrosion wear mechanism of low chromium cast iron was dominated by micro-cutting of abrasive, accompanying by corrosion action. The addition of alloying elements did not improve the corrosion wear properties of low chromium cast iron obviously, because the amount of carbide and its hardness was decreased when the alloying elements were added into low chromium cast iron as well as the amount of silicon element was increased.
