“…Corrosion is very dangerous, either directly or indirectly. The corrosion resistance of steel is influenced by the alloying elements contained in it [3]. The mechanical properties and corrosion resistance of steel depend on the chemical composition and the microstructure contained in it [4], such as nickel (Ni), chromium (Cr), and manganese (Mn).…”

“…The mechanical properties and corrosion resistance of steel depend on the chemical composition and the microstructure contained in it [4], such as nickel (Ni), chromium (Cr), and manganese (Mn). These three elements will impact the corrosion resistance properties [3]. Corrosion is damage or deterioration of metal caused by electrochemical reactions because the surrounding environment influences it.…”

In the industrial world, carbon steel has been widely used. Corrosion of carbon steel cannot be avoided, so many studies have been carried out to overcome Corrosion. One of the efforts to overcome Corrosion is by coating. Low-carbon steel coating was done by combining TiO2 and polyaniline (PAni), which was carried out by electrodeposition. A carbon steel specimen that has been coated is corroded by immersing it in an acid and salt medium. After Corrosion, the specimen is tested for hardness. The specimen without inhibitor has a hardness value of 131 kg/mm2, while the specimen with the highest hardness value is a specimen coated with PAni 10-1 M and TiO2 10-4 M at 336 kg/mm2. Based on visual observation, the Corrosion that occurs is uniform.

Method has been carried out. Research is done on mild steel zincalume type with immersion treatment (NaCl 3.5%) for 10 days, and 30 days and without immersion. Mild steel is laser irradiated (Nd-YAG 1064 nm, 7 ns) with energy of 120 mJ, and the data is taken with an accumulation of 3, delay time of 0.5 µs. Elements identification is done by taking data from up to 75 μm from the surface. The results of the analysis with LIBS showed immersion for 10 days, the corrosion rate and hardness of mild steel increased with 30 days immersion. The increase in the corrosion rate of mild steel is indicated by decreasing the value of dissolved oxygen intensity, the electrochemical reaction is fast. The decrease in the corrosion rate is indicated by the increase in the intensity value of Zn and Al elements associated with the formation of a passive film on the metal surface as a protective layer to protect further corrosion attacks.

“…Other than the corrosion media, the corrosion time also provides a significant influence on the corrosion rate. Earlier experiments show that the longer exposing time can lead to a higher corrosion rate [14], [15].…”

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.
