“…The nitriding treatment is widely used to protect the degradation of mechanical parts surface against the wear and the corrosion. Moli et al [10] showed that the shaft of a palm oil press degrades due to the fact of this oil contains a high concentration of palmitic and oleic acids. For avoiding the problem, the authors treated this piece by gas nitriding.…”

The present study has been conducted in order to obtain iron nitrides layer on AISI4140 steel by using plasma nitriding treatment. As one of several parameters of this process, the nitrogen rate ranging from 10 to 70% with a step of 20% was chosen. The structure, the morphology, the thickness and the hardness of iron nitrides layer were investigated. As a result, the improvement of surface hardness of nitrided steel was identified related with the increase of compound layer thickness due to the increase of activation rate. The steel substrate treated at high activation rate presents hardness 3 times higher than that of untreated steel.

“…For medium steels, Adoe et al studied the temperature effect of AISI 1045 corrosion rate, additionally, Rosidah et al examined the corrosion rate of the coated AISI 1045 in NaCl solution for 48 hours [5], [6]. Irianty et al and Moli et al investigated the corrosion rate of the medium alloy steel which is AISI 4140 with inhibitor and gas nitriding treatment, respectively [7], [8]. Moreover, the research on the corrosion behavior of stainless steel mostly used SS 304 as the material.…”

Previous researches have carried out studying the corrosion behavior of steels, the most frequently used steels are medium carbon steel, alloy steel, and stainless steel. This is due to their wide range of applications. So, corrosion behavior is necessary to be analyzed for every steel type because of its wide function. This study was aimed to analyze the corrosion rate, macrostructure, and the XRD results of the AISI 1045, AISI 4140, and SS 304 which represent every steel type. Then, the steels were exposed to the 0.5M H2SO4 solution with various corrosion times. The variation of the corrosion time was 48, 96, and 144 hours. The results of this study revealed that AISI 1045 showed the highest corrosion rate with the value of 183.7 mpy at 144 hours of the time variation. All specimens obtained an increase in the corrosion rate with the increase in the corrosion time. Furthermore, for the macrostructure results, AISI 1045 and AISI 4140 gave obvious rust on the surface of the specimens for all time variation. The corrosion spots appear in the time variation of 96 and 144 hours for SS 304 specimens. XRD analysis confirmed the presence of metal oxides as corrosion products.
