Abstract

A system or method for heat treating a localized area of a component part includes providing a susceptor, shaping the susceptor to conform to the component part, a component part, and a heat source, heating the susceptor by the heat source, and introducing the susceptor to the desired target area of the component part for a controlled or predetermined interval as necessary to achieve a desired metallurgical effect to take place with respect to the desired target area.

First claim

What is claimed is:

1. A method for heat treating a localized area of a component part, comprising:
providing a susceptor, a component part, and a heat source;
shaping the susceptor to include a feature corresponding to a negative impression of a desired target area of the component part;
heating the susceptor by the heat source separately from the component part;
controlling the temperature of the susceptor to a predetermined temperature suitable for heat treatment of the desired target area of the component part prior to introducing the susceptor to the component part; and
applying the susceptor to the desired target area of the component part after the susceptor reaches the predetermined temperature for a controlled or predetermined interval as is necessary to achieve a desired metallurgical effect to take place with respect to the desired target area.

2. The method of claim 1 , wherein shaping comprises shaping the susceptor to conform to the component part.

3. The method of claim 1 , wherein shaping comprises shaping the susceptor as a negative impression of least a portion of a profile of the component part.

4. The method of claim 1 , further comprising sizing the susceptor for heating a desired target area of the component part.

5. The method of claim 4 , wherein heating is achieved without affecting properties of the component part adjacent to the targeted area.

6. The method of claim 1 , further comprising applying heat shielding to areas of the component part adjacent to the target area.

7. The method of claim 1 , further comprising applying local cooling to areas of the component part adjacent to the target area.

8. The method of claim 1 , further comprising controlling and separating the target area of the component part from an adjacent area of component part in which heat treating is not intended.

9. The method of claim 1 , further comprising providing a plurality of grooves in the susceptor, each groove comprising a negative impression of a target area of a plurality of component parts.

10. The method of claim 9 , wherein the plurality of component parts is heat treated with the susceptor.

11. The method of claim 9 , wherein multiple shapes are treated with the susceptor.
