Abstract

Pack carburizing is a method of surface hardening of steel which is carried out by diffusing carbon into the material where the carbon is initially solid. This study aims to determine the effect of pack carburizing treatment on the microstructure and hardness of AISI 1010 steel. The material was then cooled slowly in the oven to a temperatur of 150oC which was then followed by air cooling. Single Quenching is then carried out by reheating the carburizing material to a temperature of 870oC and then holding it at that temperature for 60 minutes. Quenching is done by cooling the material quickly using a cooling medium of varying viscosity. The results of the composition test showed an increase in carbon content to 4.1159%. The results of microstructure observations showed that a massive pearlite structure was formed to a depth of ± 0.794 mm on the surface of the carburizing specimen. The results of the hardness test using the Vickers method showed that the hardness value of the raw material increased after carburizing to 217.88±5.13 HV due to the formation of a pearlite structure. With this increase in hardness, the application of AISI 1010 Steel material becomes wider. Keywords: Carburizing, Quenching, Viscosity, Hardness, Microstructure

Abstract

Indonesia has abundant resources, especially in natural resources (SDA), one of which is nickel. Nickel is a metal that is loved by many people because of the rapid development of technology in creating electric transportation, in particular, the application of nickel is one of the batteries. Nickel resources in the world are available in the form of Nickel Oxide as much as 60% and the remaining 40% is available in the form of sulfide reserves. Currently, there are 2 extraction methods, namely hydrometallurgy (Caron Process) and pyrometallurgy (Rotary Kiln Electric Furnace). Hydrometallurgy is a process used for nickel ore that has a grade of < 1.5%, while pyrometallurgy is still used for nickel ore that has a Ni content of < 3%. At present, the most common hydrometallurgical process is applied to limonite nickel ore. While the extraction process in pyrometallurgy uses saprolite nickel ore. Nickel metal processing, currently the best and the cheapest in terms of production costs is the hydrometallurgical process followed by the pyrometallurgical process. Using low-grade nickel is more suitable for manufacturing battery manufacture. The reason is that the Limonite Nickel reserves are more and can increase the selling value of the nickel ore. Thus, it is necessary to pay attention to the development in the processing process to increase the purity of the nickel-metal itself.
