A Comparative Wear Study On Heat-Treated Aluminium-Lithium Alloy And Pure Aluminium
A.S. Md Abdul Haseeb
Wear behaviour of solution-treated and aged aluminium-lithium alloy (2.5% Li, 2% Cu, 1% Mg and 0.15% Zr) was compared with that of pure aluminium. Wear tests were carried out in ambient air in a pin-on-disc type apparatus under dry sliding conditions using hardened steel disc as the counterbody. A normal load of 10 N and a linear speed of 0.98 m s-1 were used during the tests. Microscopic investigation, microhardness measurement on the subsurface of wear scars on pins, X-ray diffraction study and morphological examination of wear debris were done to elucidate wear mechanism. It has been ...
