| Abstract Scope |
Abrasion of Body Structure for Gondola Car Body or Dump Body by bulk materials increases maintenance costs and wear. This study evaluates aluminum alloys as a lightweight alternative to steel, testing their tribological performance against abrasive bauxite and alumina. The wear resistance of 5052-F, 6061-T6, and 6082-T6 aluminum alloys were benchmarked against HSLA 340 steel. Abrasiveness of the cargo was quantified using the Bond Abrasion Index (AI), which strongly correlated with measured wear on the metallic specimens. Results indicate that heat-treated 6082-T6 and 6061-T6 alloys exhibit significantly higher abrasion resistance than the non-heat-treatable 5052-F alloy. While the steel reference showed the least material loss, these findings provide critical data supporting the selection of heat-treated 6xxx series aluminum alloys for constructing durable, lightweight Body Structure, ensuring enhanced performance in demanding for bauxite or aluminum based abrasive environments. |
