“…Generally, catalysts are used to accelerate the carbon diffusion to the component surface during the pack carburizing process. Barium carbonate (BaCO3), sodium carbonate (NaCO3), and calcium carbonate (CaCO3) are a few examples of the various carbonates that are employed as catalysts in the carburizing process [5]. Numerous researchers have attempted to employ calcium carbonate from various types of shells as a catalyst in the carburizing process due to its widespread availability and simple accessibility [6][7][8][9][10].…”

The feasibility of strombus turturella or dog conch shell powder (DCSP) as a catalyst of the carburizing process was investigated. The microstructure and wear characteristics of carburized specimens at various carburizing times were determined and compared. The microstructures and chemical compositions of the carburized specimen were observed by Scanning Electron Microscopy (SEM) machine with a detector energy dispersive spectroscopy (EDS). The wear characteristics were detected by a Pin-on-disk wear testing machine. While the worn surface morphology of carburized specimens was examined by Scanning Electron Microscopy (SEM) machine. The number of martensite structures of carburized specimens increased by increasing the carburization time from 3 to 12 hours. From the results, it is found that the volume loss value of 0.1 mm3, and wear depths value of 0.18 mm were obtained from carburized specimens prepared with 40% DCSP and carburizing time of 12 hours. This result is much better than that obtained by carburizing times of 6, and 3 hours, respectively. Moreover, the worn surface morphology results depicted that the carburized specimens for carburization times of 3, and 6 hours exhibit more severe spalling, wear debris, and extensive adhesion wear and grooves than that achieved of carburized specimens with a carburizing time of 12 hours. The results clearly showed that the wear characteristics of carburized specimens improved with increasing carburizing time.

“…The results showed that a significant improvement in the hardness, tensile strength, yield strength, and elastic modulus could be obtained given an appropriate choice of carburizer (i.e., GBC or BC). Miswanto et al [30] significantly improved the carbon content of low-carbon steel by utilizing a combination of cow bone and coconut shell charcoal as carburizing media.…”

The feasibility of using coconut shell powder (CSP) and dog conch shell powder (DCSP) as carburizing media in the pack carburization of SCM 420 steel was investigated. The carbon content and surface hardness of the carburized specimens prepared with different CSP:DCSP ratios and carburizing durations were examined and compared. A CSP:DCSP ratio of 60%:40% and an extended carburizing time of 12 h were found to increase the carbon content of the carburized specimens to 1.14 ± 0.007 wt%. Furthermore, the surface hardness was significantly improved to 961.3 ± 4.918 HV following water quenching. Finally, the thickness of the carburized layer of the quenched specimens increased by around 2.5 times as the carburizing duration was increased from 3 to 12 h.
