摘要：
Surfaces of bulk glassy Zr(59)Ti(3)Cu(20)Al(10)Ni(8) samples were shot-peened for different times and their corrosion behaviour was tested in 0.01 M Na(2)SO(4) + xM NaCl (x = 0; 0.01; 0.1) and 6 M HCl. Slight improvement of spontaneous passivity but a decrease of pitting resistance are detected with prolonged shot-peening duration. The corrosion damage evolution is governed by the nature of the mechanically generated defects and their surrounding stress fields. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd.
