Abstract

This work presents first attempts to study influence of severe plastic deformation (SPD) procedure on material surface performance in high speed erosion conditions. Ultrafine-grained Aluminum alloy samples (after high pressure torsion) and were subjected to intensive erosion by corundum particles together with their coarse-grained counterparts. Particles were 100 pm in diameter and were accelerated via air flow up to 40-200 m/s velocities in a special experimental setup. Surface roughness measurements were performed to compare surface properties of SPD-processed and original samples. Additionally, SPD processing appeared to increase noticeably threshold velocity of the surface fracture process. A structural analysis of fracture surfaces was carried out on the samples in initial state and after erosion with different intensities. Copyright (C) 2016 The Authors. Published by Elsevier B.V.
