Surface hardening processing worker (carburizing, nitriding types)
ひょうめんこうかしょりこう（しんたん、ちっかによるもの）
Industry & Occupation
Classification
Summary
Specialist who forms a surface hardening layer using chemical heat treatments such as carburizing and nitriding to improve the surface hardness and wear resistance of metal parts.
Description
Surface hardening processing workers handle chemical heat treatments that diffuse carbon (carburizing) or nitrogen (nitriding) into the surfaces of metal parts. Operators manage furnace heating and cooling cycles, strictly controlling gas atmospheres, temperatures, and times. After processing, they measure hardness and perform microscopic inspections to confirm compliance with standards. This is an essential process for improving wear resistance and strength in automotive and machinery parts, mainly involving standing work on factory production lines. Safety management and physical stamina are required due to high-temperature environments and handling of heavy objects.
Future Outlook
Stable demand is expected due to the pursuit of higher performance in the automotive and machinery industries. It is anticipated that demand for highly specialized personnel will increase as optimization technologies for heat treatment processes using IoT and AI become widespread.
