CORROSION AND EROSION-CORROSION BEHAVIOR OF A Co-BASED ALLOY AND A Ni-CONTAINING AUSTENITIC CAST IRON

摘要

The response of two engineering materials (Co-based X-40 and an austenitic cast iron BS 3468) toerosion-corrosion has been investigated in liquid-solid impingement conditions. The characteristics ofthe corrosion behavior of the materials in static and erosion-corrosion conditions have been comparedand contrasted. It has been shown that on both materials the contribution to material degradation ofcorrosion and corrosion-related processes is significant and can account for in excess of 40% of the totalmaterial mass loss.
