Abstract:
A heat treatment was carried out using the solid carburizing process on an AISI 1018 low carbon steel. The purpose of this treatment is to enrich the surface of the steel with carbon by means of the diffusion mechanism, so that the surface layer of the steel contains a higher concentration of carbon than the original concentration of carbon contained in this steel.
Consequently, the case-hardened steel acquires a combination of properties
The cementitious components used consisted of 90% charcoal and 10% barium carbonate (BaCO3). The cementitious components used are made up of 90% charcoal and 10% barium carbonate (BaCO3), the temperature in the furnace was 930°C, with a permanence of 8 hours, then the steel piece was cooled in oil for quenching and subsequently tempered at 230°C for a period of 45 minutes.
total depth is defined as the perpendicular distance from the limit of the surface to the end of the hardened zone. On the other hand, the microstructure obtained on the surface was of a martensite phase and the core was of a pearlite and ferrite phase, in this treatment it was possible to obtain a dual phase steel, achieving greater hardness on the surface due to a high carbon content, but keeping a lower content in its core. Dual phase steels are excellent in conditions where there are high impact stresses and constant surface wear, for example: in shafts, bolts, gears and transmission parts which are in constant metal to metal friction, abrasion and impact among others
