Abstract
This work examines the effect of grain size on the surface hardness of pack carburizing mild steel. The pack carburizing procedure aims to add carbon into surface of speciments (mild steel SS400). The carbon source commonly used in previous researches is charcoal teak, coconut shell charcoal, bamboo charcoal and palm cernel shell charcoal. The corn cob charcoal has not been used in previous studies. In the study, used corncob charcoal with a variety of grain sizes, A carburizer composed of corn cob charcoal has been used for study together with barium carbonate (BaCO3) as energizer. The procedure was performed at carburizing temperatures of 900 oC and soakng period of 5 hours per day. Hardness evaluation was conducted in the metal samples. The outcome of the analysis demonstrated that surface hardness quantity of the light steel enhanced with a sway of grain dimensions of corn cob charcoal. The best package carburizing impact was attained in wheat cob charcoal of 150 μm grain dimensions.
