Characteristics of nitriding treatment and gas nitriding treatment as surface hardening processes.
Surface hardening methods in heat treatment. A detailed introduction to the characteristics of each surface hardening treatment method.
Nitriding treatment is classified as one of the surface hardening methods in heat treatment. It is a process in which nitrogen diffused from the surface of steel combines with various metallic elements to form hard nitrides, thereby hardening the surface of the steel. The purpose of nitriding treatment is to improve wear resistance, fatigue resistance, corrosion resistance, and heat resistance. Here, we introduce the characteristics of nitriding treatment and gas nitriding as surface hardening treatments. 【Characteristics of Each Surface Hardening Method (Excerpt)】 ■ Nitriding Depth of hardened layer: ○ / Hardness: ○ / Fatigue resistance: ○ / Deformability: ○ / Wear resistance: ◎ / Spalling resistance: ◎ / Heat resistance: ○ / Corrosion resistance: ○ ■ Carburizing Depth of hardened layer: ◎ / Hardness: ○ / Fatigue resistance: ○ / Deformability: △ / Wear resistance: ○ / Spalling resistance: ○ / Heat resistance: △ / Corrosion resistance: △ ■ Siliconizing Depth of hardened layer: ○ / Hardness: ○ / Fatigue resistance: △ / Deformability: △ / Wear resistance: ○ / Spalling resistance: ○ / Heat resistance: ◎ / Corrosion resistance: ◎ ■ Flame Hardening Depth of hardened layer: △ / Hardness: △ / Fatigue resistance: △ / Deformability: △ / Wear resistance: ○ / Spalling resistance: ○ / Heat resistance: △ / Corrosion resistance: △ *For more details, please download the PDF or feel free to contact us.
