Abstract
A cladded article may include a first metallic layer, a clad layer, and a first solid-state welding interface region positioned between the clad layer and the first metallic layer. The clad layer may include a first clad layer region having a first clad layer thickness in a thickness direction of the clad layer and a second clad layer region having a second clad layer thickness in the thickness direction of the clad layer. The second clad layer thickness may be greater than the first clad layer thickness.
Claims15
A cladded article comprising:
- a first metallic layer;
- a clad layer, the clad layer comprising:
- a first clad layer region having a first clad layer thickness in a thickness direction of the clad layer;
- and
- a second clad layer region having a second clad layer thickness in the thickness direction of the clad layer, wherein:
- the second clad layer thickness is greater than the first clad layer thickness;
- a first solid-state welding interface region positioned between the clad layer and the first metallic layer-;
- the second clad layer region comprises a projection for forming a joint with another article;
- the second clad layer region comprises a plurality of foils;
- and
- a foil of the plurality of foils is formed of a material comprising tantalum or a tantalum alloy.
A method of manufacturing a cladded article, the method comprising:
- providing a first metallic layer comprising a first material and having a first metallic layer surface;
- providing a clad layer comprising a second material and having a substantially uniform first clad layer thickness;
- solid-state welding the clad layer to the first metallic layer surface;
- and
- after solid-state welding the clad layer to the first metallic layer surface, creating a modified clad layer region by bonding material to an outer surface of the clad layer opposite the first metallic layer, wherein;
- a second clad layer thickness in the modified clad layer region is larger than the first clad layer thickness;
- the second clad layer region comprises a plurality of foils;
- and
- a foil of the plurality of foils is formed of a material comprising tantalum or a tantalum alloy.
A cladded article comprising:
- a base layer;
- a clad layer;
- a first solid-state welding interface region positioned between the clad layer and the base layer;
- a clad layer projection bonded to an underlying portion of the clad layer;
- wherein:
- the clad layer projection comprises a plurality of layered foils ultrasonically welded to the clad layer;
- a foil of the plurality of foils is formed of the material comprising tantalum or the tantalum alloy;
- the clad layer projection is configured to form a joint with another article;
- and
- the clad layer has a higher melting point than the base layer.
