INCREMENTAL SHEET FORMING FOR FABRICATION OF COLD SPRAYED SMART SUSCEPTOR

摘要

PROBLEM TO BE SOLVED: To provide an induction heating system for manufacturing a cold sprayed smart susceptor, and a specific part to which the smart susceptor is used.SOLUTION: A smart susceptor includes a ferromagnetic material cold sprayed onto a tool. The tool may be a sheet metal component formed to a desired shape by incremental sheet forming. The smart susceptor may be heated up by eddy currents generated in the ferromagnetic material by the oscillating electromagnetic field. The smart susceptor may be designed to have a desired Curie temperature based on the composition of the ferromagnetic material. The smart susceptor is formed into a desired shape by cold spraying ferromagnetic material onto a tool already formed into the desired shape. The smart susceptor may be removed from the tool by thermally shocking the smart susceptor and the tool and may be used to heat a part to be formed.
