Abstract

The prediction and control of wear is one of the most essential problems emerging in the design of cutting operations which has to be checked through local production. This work therefore studies the effects of carburization on mechanical properties of recycled steel with Perm Kernel Shell (PKS) as carbon additives. 40 pieces of recycled Steel tools were used for the project. The tools were carburized with 40 kg of pulverized carbon of Perm Kernel Shell using 30 % Barium trioxocarbonate (V) as an energizer in a muffle treatment furnace of about 1500oC. Each sample was held at temperature of 800oC, 850oC, 900oC and 950oC for 60, 90 and 120 minutes holding time. The performance evaluation of the tool was done by using the tools (carburized and un-carburized) to machining low and medium carbon work piece on the lathe machine and also measured its impact/toughness using impact tester. The results shown best cutting performances and toughness in carburized tool of higher impact/ toughness value of 24 J over control sample of 17 J. The result of the performance evaluation tests corroborated the higher qualities of the carburized cutting tool over un-carburized type.
