Enhancing Resistance

Abstract

This work looks about the way friction stir processing (FSP), improves the aluminium alloy's (AA) 6082 resistance to wear and corrosion. Two types of samples were fabricated and taken from the FSP'ed stir zone surface for (i) pure AA6082 and (ii) AA6082 with TiC and graphite hybrid surface composites. Rate of wear and co-efficient of friction were evaluated under various conditions, indicating that the hybrid surface composites exhibited superior resistance to wear and reduced co-efficient of friction related to pure AA6082 surfaces. SEM analysis provided insigrhts into the wear mechanisms, while potentiodynamic polarization curves assessed corrosion behaviour in a 3.5 wt.% NaCl solution. Incorporating TiC and graphite particles via FSP enhances both wear and corrosion resistance of AA6082, rendering it suitable for applications demanding durability and reliability in harsh environments.
