Abstract

Resistance to wear is an important factor in design and selection of structural components in motion and in contact with a mating surface The present work deals with studies on fretting wear behavior of mechanically alloyed 1 0 wt % nano-Y(2)O(3) dispersed 71 0Fe-25 5Cr-2 0Al-0 5Ti (wt %) ferritic steel consolidated by hot isostatic pressing at 600 800 and 1000 C under 1 2 GPa uniaxial pressure applied for 1 h The wear experiments were carried out in gross slip fretting regime against 6 mm diameter tungsten carbide ball at ambient temperature The highest resistance to fretting wear has been observed in the alloy sintered at 1000 C The fretting Involves localized plastic deformation and oxidation as evidenced by post wear surface profile and micro-compositional analysis respectively (C) 2010 Elsevier B V All rights reserved
