Sažetak
Carburizing is a thermochemical surface hardening process which is used to improve the wear resistance while maintaining toughness and fatigue strength of the core. Carburizing steels are lowcarbon steels which surface layer is carburized to the achievement of high-carbon martensitic case with increased abrasion wear resistance. In the experimental part of the paper, the effect of carburizing on the surface hardness and case hardness depth of carburizing steels 20MnCr5 and 18CrNi8 was investigated. The process of carburization was carried out in a gas carburising furnace at the same parameters for both steels. The samples were quenched directly into oil and then tempered. After the treatment, a metallographic analysis was carried out and case hardness depths were determined. The obtained test results have shown that initial composition of carburizing steel effects on case hardness depth and does not effect on the value of surface hardness after carburizing.
