Japanese Patent JP5927646

B2

Provided is a method of treating a metal surface, which can improve surface properties of a target metal, such as surface hardness and wear resistance in a simple manner and at low cost using very simple equipment alone, and which can prevent the deterioration of the metal to create high added value. The present invention is comprised of a method of treating a metal surface, characterized in that: heat-treating a target metal (10) to be surface-modified in nitrogen gas atmosphere (S), in such a state where the target metal (10) is buried in a carbon source powder (12) comprising a carbon powder and a powder of iron or an iron alloy mainly comprising iron and containing carbon, whereby the surface of the target metal (10) is at least nitrided or nitrogen-absorbed to modify the surface.
