A joining method includes the steps of placing a brazing element between an interface area of a first ceramic piece and an interface area of a second ceramic piece to create a joining pre-assembly, placing the components of said joining pre-assembly into a process chamber, removing oxygen from said process chamber, and heating at least said brazing element of said joining pre-assembly, thereby hermetically joining said first ceramic piece to said second ceramic piece. The brazing element consists of Nickel and Carbon.

A suppressor having a body and a first connector half coupled to the body, wherein the first connector half includes a first component that includes at least one channel and a first surface; and wherein the body provides a second surface, wherein a gap between the first surface and the second surface defines at least one track; wherein the gun includes a second connector half comprising at least one protrusion, wherein the protrusion and channel have corresponding shapes that allow the protrusion to be inserted through the channel and into alignment with the track, wherein the first component may be rotated with respect to the protrusion and the body to bring the protrusion out of alignment with the channel so that the first and second surfaces clamp the protrusion to thereby secure the first connector half and second connector half with respect to each other.

A composition of a nickel based alloy mixture which can be used for welding via especially liquid metal deposition or as a powder bed of an additive manufacturing method. A metallic powder mixture includes (in wt %): a cobalt (Co) or nickel (Ni) based super alloy with a content of 20% to 60%, a NiCoCrAlY-composition with a content of 70% to 30% and a metallic braze material with a content between 10% to 5%. The melting point of the braze material is at least 10K lower than the melting point of the nickel or cobalt based superalloy.

By using a solder paste including powder of a lead-free solder alloy mainly composed of Sn and a metal particle with a melting point higher than a melting point of the lead-free solder alloy, in which the metal particle is formed. of a Cu—Ni alloy having a Ni content of 0.1 to 90% by mass, or formed of a Cu—Co alloy having a Co content of 0.1 to 90% by mass, a solder bonded body that has heat resistance, thermal conductivity, and reliability higher than ever can be formed.

A method may include removing a portion of a base component adjacent to a damaged portion of the base component to define a repair portion of the base component. The base component may include a cobalt- or nickel-based superalloy, and the repair portion of the base component may include a through-hole extending from a first surface of the base component to a second surface of the base component. The method also may include forming a braze sintered preform to substantially reproduce a shape of the through-hole. The braze sintered preform may include a Ni- or Co-based alloy. The method additionally may include placing the braze sintered preform in the through-hole and heating at least the braze sintered preform to cause the braze sintered preform to join to the repair portion of the base component and change a microstructure of the braze sintered preform to a brazed and diffused microstructure.

The present invention relates to a method of producing a composite rod from a braze material and a sheet of material comprising cermet. The method comprises scoring a surface of the sheet to produce at least one line of localised stress and subsequently causing the sheet to break along the line or localised stress, thereby to produce a plurality of cermet chunks. The cermet chunks can be combined with the braze material to produce the composite rod. In a particular embodiment, the sheet of material may be a used cermet cutting tip.
