Abstract

The effect of BaCO3 on bakau’s charcoal as a carburizer for pack carburizing process was investigated. Bakau’s charcoal that was made from bakau’s tree were sifted on 30 mesh sieve. BaCO3 was added into bakau’s charcoal with composition of 0, 15, 20, 25, and 30 % wt. The pack carburizing was conducted at 850 0C for 2 hours. Low-carbon steel of 0,156 %C was used as specimen. After carburized, all specimens were reheated at 850 0C, hold it for 5 minutes, and then they were quenched into water at 28 0C. The result shows that BaCO3 is effective in enhancing bakau’s charcoal as a solid media in pack carburizing proces. Adding of 20, 25 dan 30% wt BaCO3 gives case depth respectively 190 m, 250 m dan 325 m. Martensite structure that arise on steel surface after quenched, indicate quantity increase of carbon atoms. Keywords: Bakau’s Charcoal, Pack Carburizing, Barium karbonat.
