Abstract

This study reports a few observations made regarding the dry sliding wear behaviour of a newly developed zinc-aluminium alloy. A conventionally used leaded-tin bronze and standard zinc-aluminium alloy have also been characterized under identical test conditions in order to assess the wear performance of the newly developed composition with respect to the converSonal alloys and to understand the factors centrolling the wear response. The study indicates that the bronze exhibited considerably inferior wear behavianr than the zinc-based alloys. In fact, the former revealed "chipping off'' of material to such an extent that the specimens became quite small well before traversing the predeterminea~ sliding distance at a specific pressare. As a result, no seizure pressure could be determined for the bronze. On the contrary, the ~,~inc-based (standard as well as thv modified) alloys showed considerably lower wear rates and better seizure characteristics than the bronze. The wear behaviour of the alloys has been explained on the basis of their microstructural features and further substantiated through the characteristics of the wear surfaces, subsurface regions and debris particles generated during the tests. The analyses of the wear surfaces, subsurface regions and debris particles also enabled the operative wear mechanisms to he underste.od.
