Nitriding Worker (Chemical Industry)
ちっかこう（かがくこうぎょう）
Industry & Occupation
Classification
Summary
This occupation involves operating nitriding furnaces to infuse nitrogen into the surface of metal parts to form a hardened layer, managing temperature and pressure, conducting quality inspections, and ensuring safety management.
Description
Nitriding workers specialize in nitriding treatments that change the metal surfaces of automotive or mechanical parts and tools into nitrogen-containing layers to improve wear resistance and fatigue strength. They operate processing equipment such as gas nitriding, salt bath nitriding, and plasma nitriding, controlling temperature and pressure, and managing processing times. After treatment, they conduct quality inspections using hardness measurement and microscopic observation, and if it does not meet standards, they analyze causes and perform reprocessing. During operations, which involve high-temperature environments and hazardous gases, they are required to inspect safety devices and adhere to work procedures.
Future Outlook
Due to the demand for higher performance and quality in metal parts, the need for surface treatment technologies remains stable or is increasing. Particularly in fields such as automobiles, aircraft, and electronic components, high-precision nitriding treatments are required, and the value of skilled technicians will rise.
