Abstract
Pack Carburizing process is done to get a high hardness number on the surface of the shaft but ductile in the core. The research has been done by using carburizer media of teak wood charcoal as source of carbon element and CaCO3 as the source of Ca element as energizer or catalyst. Alternative carburizer media applications are still rarely performed. This study discusses the effects of different carburizer media on the fatigue strength of mild steel used in the power tiller shafts and wide industrial applications. Carburizer media used is teak wood charcoal and Pomacea Canalikulata Lamarck (PCL) shell powder. The composition of (PCL) shell powder used: 10, 20 and 30 (% wt). Carburizing is done at temperature 9500C with Carburizing time for 5 hours, followed by tempering with temperature variations 2500C, 3000C, 3500C and quenching with salt solution (30% NaCl + water) Then performed Rotating Bending Test, observation with SEM (scanning electron microscop), to know the fatigue strength and microstructure specimens. In conclusion, The tempering process followed by quenching in 30% NaCl solution after pack carburizing, can increase the fatigue strength.
