Tufftride Worker (Nitriding Operation)
たふとらいどこう（ちっかさぎょう）
Industry & Occupation
Classification
Summary
A manufacturing technical position that operates high-temperature furnaces to diffuse nitrogen into the surface of metal parts using nitriding gas or salt baths, thereby improving wear resistance and fatigue strength.
Description
Tufftride workers (nitriding operations) are specialists who operate nitriding furnaces to diffuse nitrogen into the surface of metal parts, such as automotive and industrial machinery components, to enhance wear resistance and fatigue resistance. They strictly adhere to specified temperatures and processing times using methods such as gas nitriding, ion nitriding, and salt bath nitriding, while adjusting the flow rate of atmospheric gas and furnace pressure. After processing, they perform quality inspections using hardness testers and metallurgical microscopes, and if the results do not meet standards, they make adjustments or reprocess. Safety management and equipment maintenance are also important tasks.
Future Outlook
With increasing demand for high-performance materials in automotive and aircraft parts, quality requirements are becoming stricter, while automation of equipment and IoT adoption are advancing. Technicians with advanced process knowledge will remain in stable demand.
