Abstract

The research was conducted at the Laboratory of Material Mechanics, Department of Mechanical Engineering, Mataram University. The purpose of this research   determined  the effect of the Pack Carburizing  parameters (temperature, soakin  time and carburizer media composition) on the thickness  of calsium carbida layer  (CaC), which is formed on the surface of low carbon steel. The thickness of the calcium carbonate layer affects the surface hardness number  of low carbon steel. This research used low carbon steel  grade SS400 as the specimen. Carburizer media is a mixture of corncob charcoal powder and Pinctada maxima shells  powder (PMSP).  Packs Carburizing was carried out at various temperatures: 875 0C, 900 0C, soaking  time: 1,2,3 hours and the percentage of PMSP on the carburizer media: 10%, 20%, 30%. The results of the research show that the temperature carburizing , soaking time and the addition of PMSP  affect the thickness of the calcium carbide layer on the surface of SS400 steel which is subjected to pack carburizing process. This is indicated by an increase in the surface  hardness number of 421%, the wear resistance 62,2 %.  the thickness of the calcium carbide layer 1050 µm, the formation of pearlite structure, at the carburizing temperature of 900 0C,  soaking time 3 hours and 30% addition of PMSP.
