Influence of Equal Channel Angular Extrusion on Erosion Wear Resistance of Ti5553

Abstract

Abstract:

Abstract： A novel method was proposed to improve the erosion wear behaviour of Ti5553 exposed to seawater with quartzes, in which the erosion performance of Ti5553 treated by equal channel angular extrusion (ECAE) was compared with that of counterpart without ECAE treatment. The results indicate that the sample treated by ECAE demonstrates a significantly improved erosion wear resistance due to the grain refinement introduced by ECAE, resulting in the improvement of tensile strength, ductility, toughness and microstructure of the sample. Scanning electron microscope (SEM), assisted by quantitative analysis utilising Matlab, was adopted to generate the surface morphology of the samples. With the exploration of the microstructure, mechanical properties and erosion mechanism evolution dependence of erosion wear behaviour, it is found that the erosion mechanism of the sample treated by ECAE has impact deformation and ploughing, accompanied by severe scratching and crater cracks while that of the sample without ECAE treatment has slight impact deformation and ploughing, with shallow scratching and crater cracks.
