Abstract
A process for treating a surface coating of a bulk metal part, comprises the steps of placing, in a cavity, at least one what is called metal part including what is called a surface coating that is able to absorb microwaves at the frequency ν0, the cavity being surrounded by one or a plurality of first susceptors the dimensions, material and arrangement of which are configured to screen the microwaves at the frequency ν0, in the vicinity of each the metal part, and in emitting the microwaves at the frequency ν0 into the cavity.
Claims20
A process for treating a surface coating of a bulk metal part, comprising the steps of:
- 1) placing, in a cavity, at least one bulk metal part including a surface coating able to absorb microwaves at the frequency ν0, said cavity being directly surrounded by one or a plurality of first susceptors having dimensions, material, and an arrangement of which are configured to screen said microwaves at the frequency ν0, in the vicinity of each said bulk metal part;
- 2) emitting said microwaves at the frequency ν0 into said cavity;
- 3) placing said one or plurality of first susceptors and said at least one bulk metal part in a first thermal confinement;
- and
- 4) surrounding said first thermal confinement with one or a plurality of second susceptors.
