Cladded article with solid-state welding interface and tantalum material
A recently granted patent (Publication Number: US11897228B2) discloses a cladded article comprising a first metallic layer and a clad layer with varying thickness regions, where the second clad layer region has a greater thickness than the first. The clad layer, made of tantalum or a tantalum alloy, includes foils also made of the same material. The article features solid-state welding interfaces and is designed for forming joints with other articles. Additionally, the patent covers a method for manufacturing such cladded articles, involving solid-state welding the clad layer to the metallic layer and creating modified clad layer regions with larger thicknesses by bonding material to the outer surface of the clad layer.
Furthermore, the patent includes claims for a cladded article with a base layer and a tantalum-based clad layer, featuring solid-state welding interfaces and clad layer projections made of layered foils ultrasonically welded to the clad layer. These projections are designed for forming joints with other articles and have a higher melting point than the base layer. The patent also mentions the use of explosion welding interfaces in these cladded articles, highlighting the innovative techniques and materials used in their construction.
