Abstract

In this study, various carburizing compounds were used to pack carburised mild steel. Various weight percentages of cow bone were used as energizer in the carburizing compounds. The experiment was carried out using a muffle furnace at 900°C for 8 h. Hardness tests were taken using Vickers micro-hardness tester. The result showed that 60 wt% charcoal / 40 wt% cowbone had the best result with an effective case depth of 2.32 mm produced on the case of the carburized steel. The work showed that cowbone can be used as energizer in pack carburization of mild steel. The hardness profile plot of the 60 wt% charcoal / 40% cowbone carburized mild steel was also higher than the other compositions.

Keywords: Cowbone, energizer, case hardening, wear resistance, carbonates.
