Sliding Wear Characteristics of Zn-15Sn Alloy with Nano B₄C Reinforced Composites

Abstract

In the current investigation, high pin-on-disc wear testing equipment was used to examine the impact of modest additions of nano B4C on the wear behaviour of a Zn alloy (85Zn-15Sn). Zn-Sn alloy behaviour at a constant SD of 2000m under pressures (10N, 20N, 30N, and 40N) and sliding speeds (1.4, 1.8, 2.3 and 2.8 m/s) was investigated. Microanalysis with SEM/EDX was used to characterise the matrix and worn surfaces. According to the results, the wear rate of Zn alloy rises with rising pressures, sliding speeds and distances in all situations examined and lowers with an additional level of 8 weight per cent B4C to the Zn alloy when tested. This is brought on by the partial refinement of Zn dendrites, as well as the precipitation hardening of solid solutions. The worn surface investigation suggests that the creation of a thick oxide layer during sliding enhances tribological features.
