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 is thicker than the first. The clad layer, made of tantalum or a tantalum alloy, includes foils also composed of the same material. The article features solid-state welding interfaces and can be used to form joints with other articles. Additionally, the patent describes a method for manufacturing such cladded articles, involving solid-state welding the clad layer to the metallic layer and modifying the clad layer region by bonding material to its outer surface, resulting in regions with different thicknesses.

Furthermore, the patent includes claims related to the manufacturing process, specifying techniques such as ultrasonic welding for creating modified clad layer regions. The method allows for the creation of multiple modified clad layer regions with varying thicknesses, providing flexibility in design and application. The cladded article described in the patent features a base layer, a tantalum-based clad layer, and solid-state welding interfaces, with clad layer projections for forming joints with other articles. The use of explosion welding interfaces and ultrasonic welding for bonding foils to the clad layer ensures a robust and reliable structure suitable for various industrial applications.
