Title:
PRODUCTION METHOD OF CARBON STEEL MATERIAL AND CARBON STEEL MATERIAL
Document Type and Number:
Japanese Patent JP2010222648
Kind Code:
A
Abstract:
To provide a production method of a carbon steel material hardly causing peeling of a coating layer and having high strength and excellent durability, and to provide a carbon steel material having the above excellent characteristics.
The production method of a carbon steel material by surface treatment of a carbon steel includes: a carburizing treatment process of precipitating carbon as a solid solution or a carbide from the surface to the inner part of the carbon steel; and a molten salt treatment process of immersing the carburized carbon steel after the carburization treatment in a molten salt bath containing vanadium to convert the carbide layer into a coating layer containing vanadium carbide.
