Abstract

Carburizing is a thermochemical process through the heating of specimen in a medium that contains carbon at austenite temperature. The process aims to enhance the pearlite level (β) of steel surface in order to increase its hardness. The carburizing experiment in this study utilized ST 40 steel, carbon with an average carbon particle area of 515,735 µm² . At the experiment, the steel was mixed with carbon and heated at 780⁰C for four hours. From the test results it can be seen that carbon has an average carbon particle area of 110,671 μm² and 515,735 μm². carbon with an average carbon particle area of 515,735 µm² is more dominated by pearlite structure (β) compared to ferlit (α) while arbon with an average particle area of 110,671 μm² is more dominated by ferrite structure (α) than pearlite (β). because the diffusion process is not going well.
