Abstract
A method is disclosed for improving the production of electrical switch contacts, in particular for vacuum tubes. In the method, an electrical or electromagnetic field assists and/or effects a sintering process. In the method, the sintering process takes place on a metallic carrier, and via the method, semi-finished contact elements for electrical switch contacts, contact elements for electrical switch contacts, and/or electrical switch contacts, in particular for vacuum tubes, are produced.
Claims18
A field-assisted sintering technology (FAST) method of producing a semi-finished contact element product in which an electric or electromagnetic field at least one of supports and instigates a sintering process, the method comprising:
- providing a solid metallic substrate;
- providing a sintering material on a surface of the solid metallic substrate;
- conducting the sintering process on the solid metallic substrate and the sintering material;
- and
- producing at least one semi-finished contact element products from the sintering process for at least one of electrical switching contacts and contact elements for electrical switching contacts, wherein the metallic substrate is a contact carrier.
A device, comprising:
- at least one device to carry out a sintering process on a metallic substrate using a field-assisted sintering technology (FAST) method, in which an electric or electromagnetic field at least one of supports and instigates the sintering process, to produce a semi-finished contact element product for at least one of electrical switching contacts, a contact element for electrical switching contacts, and an electrical switching contact, wherein the metallic substrate is a contact carrier.
A method, comprising:
- using field-assisted sintering technology (FAST) method, in which an electric or electromagnetic field at least one of supports and instigates a sintering process on a solid metallic substrate and a sintering material on a surface of the solid metallic substrate;
- and
- producing semi-finished contact element products from the sintering process for at least one of electrical switching contacts and contact elements for electrical switching contacts, wherein the metallic substrate is a contact carrier.
