CARBURIZING METHOD, AND CARBURIZED STEEL COMPONENT MANUFACTURED BY USING THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a carburizing method by which the occurrence of uneven carburization and the degradation in surface hardness can be suppressed, and to provide a carburized component manufactured by using the method. SOLUTION: The carburizing method comprises: an oxidizing process (S1) of forming an oxide film on the surface of the steel containing≥3.5 mass% Cr; a carburizing process (S2) of carburizing the steel; a removal process (S3) of removing the oxide film from the surface of the steel; and a hardening process (S4) of hardening the steel.
