Abstract. Carbonitriding is a surface hardening process of steel by heating on critical temperature, quench and followed by tempering process. In this research, pack media in carbonitriding was used as a new method. Usually, this process has been obtained using gas and liquid carbonitriding methods. The specimen used in this research is low carbon steel (St. 41) consist of 0.1517% carbon, 0.1994% of silicon, 0.5631% of manganese, 0.0224% of phosphorus, and 0.047% of sulfur. Temperature for pack carbonitriding was at 700 o C, 750 o C and 800 o C and holding time variation 60 minutes and 120 minutes respectively. The result showed that carbonitriding temperature difference affect the mechanical properties of steel St. 41. Steel hardness was increased at lower holding time (60 minutes) compared to 120 minutes. The result showed that at 700 o C and 750 o C with 60 minutes variation, the steel hardness increase from 85.7 HRB to 95.7 HRB and at 800 0 C the hardness decrease to 93.1 HRB. Meanwhile, at holding time of 120 minutes, steel hardness decrease from 94.1 HRB to 92.7 HRB. This result caused by austenite phase produced at longer period of holding time.

“…The chemical composition of steel 40G2 contains elements (carbon, manganese, silicon) promoting the development of this process. It is said in [10] that the process of nitrocarburizing is applicable for hardening parts fabricated from any grade of steel, but according to our data some steels, like 40G2, manifest brittleness in this process. Our results on the variation of the impact toughness of the steels studied match the published data.…”

In this study, the rotating‐bending fatigue behavior in water of a 13Cr‐4Ni martensitic stainless steel as substrate, with two different thermochemical treatments and with a thermal sprayed coating was characterized. Hardness profiles were measured by instrumented nanoindentation. X‐ray diffraction was used to identify the phases and measure the residual stresses, and the fracture micromechanisms were characterized by scanning electron microscopy. The results show increases of 27%, 74%, and 95% in the fatigue strength from WC‐10Co‐4Cr coating, plasma nitriding and salt bath nitrocarburizing, respectively, compared with that untreated material at 106 cycles. The good fatigue behavior of the treated surfaces was found to result from an increase in the surface hardness and the generated compressive stresses that delay crack initiation.
