“…These samples were etched in a solution consisting of 100ml water, 2ml of HF, and 5ml of 30% H O 2 . This type of etching is widely used to highlight the different zones of cemented steel [9][10][11][12][13][14][15][16][17][18]. A Zwick Roell microscope was used to examine the metallographic preparation and observe the morphological details and thickness of the cemented layers.…”

“…The study aims to examine the impact of carburizing time and temperature on the transformation rate of carbon steel into cemented steel layers. Optical microscopy was used to analyze micrographs of the samples and the thickness of the carburized areas, and micro Vickers was used to measure the microhardness of cross-sectional samples of the cemented steel [11][12][13][14][15][16].…”

Low carbon steel with carbon content ranging from 0.15% to 0.3% cannot be hardened through quenching and tempering processes and there is little to no martensitic transformation occurring upon quenching. To improve the surface hardness, carburizing is commonly employed. Through this treatment, the surface composition of the low-carbon steel is altered by the diffusion of carbon, resulting in a hard outer casing with good wear resistance. This work investigates the effect of the carburizing treatment temperature and holding time on the crystallographic structure, hardness, and hardened surface layer dimension of commercial low-carbon steel 16NC6. The steel was carburized at 900°C for different holding times of 1, 2, and 3 hours. After the carburizing and quenching processes, the hardness values and the morphology of the crystallographic structure were measured and characterized.
