摘要

This work examines the synergistic effects of goat bone ash (GBA) reinforcement (3–9 wt%) on the wear characteristics of AA6082 composites under industrially relevant conditions (10–30 N load, 500–1500 m sliding distance). Employing Taguchi design and ANOVA, we illustrate that content (55.83% contribution) predominates wear performance, with 3% GBA maximizing tribofilm lubrication while preventing agglomeration-induced delamination. Surprisingly, increased loads 20 N enhance wear resistance by enhancing surface compaction, defying traditional models of abrasive wear. SEM analysis exposes GBA’s double role, creating protective oxide films while also generating particle-induced wear at more than 3%. Optimal GBA content 3% enhances tribofilm lubrication and decreases agglomeration-induced wear. Higher loads 20 N notably increase wear resistance by surface compaction, contrary to standard wear models. A combination of 3% GBA, 20 N, 500 m produces a consistent, low wear rate, offering design principles for bio-filler composites. GBA can be effectively employed as a reinforcement in aluminium composites to improve wear resistance, with the greatest results obtained by careful management of GBA content and loading conditions.
