Peningkatan Nilai Kekerasan Baja Karbon Rendah AISI 1018 melalui Proses Pack Karburizing dengan Media Batok Kelapa

Abstract

Low carbon are steels which have a composition of carbon around 0.005 to 0.3% weight. They have good ductility and flexibility so can be applied for automotive industry’s components. Unfortunately, do not possess an excellent hardness and wear resistance. Thus, to improve those properties, carburizing is obligatory required. Carburizing is a diffusion of carbon from the higher to lower concentration in a high temperature, following gradient concentration. Moreover, the process demands a source of active carbons and energizer. In this study, coconut
