In some examples, a technique may include positioning a first part comprising a ceramic or ceramic matrix composite and a second part comprising a ceramic or a CMC adjacent to each other to define a joint region at the interface of the first part and the second part. In some examples, the joint region may be heated using at least one of a laser or a plasma arc source to heat the joint region to an elevated temperature. The first and second parts may be pressed together and cooled to join the first and second parts at the joint region. In other examples, a solid braze material including a filler material and a metal or alloy may be delivered to the joint region and locally heated to cause a constituent of the filler material and a constituent of the metal or alloy to react. When reacted, the constituents may form a solid material, which may join the first and second parts.

Braze for ceramic and ceramic matrix composite components

A method of producing a ceramic weld, including identifying a ceramic first surface and a ceramic second surface to be bonded together, maintaining a non-oxidizing atmosphere over the first and second surfaces, and engaging the first and second surfaces to define a joint. An arc is generated between an electrode and the joint to create a liquid phase, and the liquid phase is cooled to yield a solid fusion layer, wherein the first and second surfaces are joined in the fusion layer.

Ceramic welds, and a method for producing the same

A toughened composite material, having a first phase defining a matrix and a plurality of typically second phase particles dispersed in the first phase matrix. Each respective particle is characterized by a predetermined geometric architecture, such as a spiral shape. The presence of the geometrically distinct dispersed second phase operates to deflect and attenuate crack propagation.

Method for toughening via the production of spiral architectures through powder loaded polymeric extrusion and toughened materials formed thereby
