Influence Of Reheating In Pack Carburizing Process With Bamboo Charcoal And Cow Bone Powder Media For Hardness Number And Impact Strength Low Carbon Steel (original) (raw)
Pack Carburizing process is the process of adding carbon element (C) into the metal, especially on the surface of the material where the carbon element is obtained from materials containing carbon so that the metal hardness can increase. Carburizing research that has been done with teak wood charcoal media and BaCO3 or NaCO3. The Pack Carburizing process is high costly. This study uses an alternative carburizing media in the form of bamboo charcoal and cow bone powder. The aim of this research is to know the difference of toughness value and hardness of low carbon steel which have undergone pack carburizing process, and reheating process of low carbon steel. The pack carburizing process was carried out at temperature 9000 C for 7 hours carburizing time. The hardening process was carried out by reheating the specimens at 900° C, for 50 minutes holding time, cooled with air-cooled media, water and water + 30% salt. Then tested toughness and hardness test. While Scanning Electron Micro...
