Özet

In this study, wear behaviour of high chromium white cast iron turbine blades used in shot peening machines was investigated against SiC and Al2O3 abrasive papers. Five different white cast iron turbine blades, with different chemical composition, were tested at constant speed under various loads of 10, 25 and 40 N. Tests were carried out for 60, 90 and 120 m travel distance. Experimental results showed that the specimen containing 3.3% C, 15.1% Cr and 2.5% Mo exhibited the least wear, while the specimen containing 2.94% C, 16.7% Cr and 1.2% Mo exhibited the most wear for both types of abrasives used. © 2004 Elsevier Ltd.
