Abstract
A method for producing a locally hardened component is provided. The method includes S1: placing a to-be-heated portion of a base component in an induction coil for induction heating to form a heated portion; S2: after a completion of the induction heating, spraying a quenching solution on the heated portion, cooling the heated portion down to room temperature, removing the base component, and tempering the base component at low temperature to obtain a quenched component; and S3: grinding, degreasing, and drying a hardened portion of the quenched component, coating a surface treatment solution on a surface of the hardened portion, curing the surface treatment solution, and performing an induction cladding on the hardened portion in a nitrogen atmosphere to obtain the locally hardened component.
