Welding rods and associated cladded articles are described herein. Briefly, a welding rod comprises a hard particle component dispersed in a nickel-based alloy matrix or cobalt-based alloy matrix, the hard particle component comprising tungsten carbide particles having an average size of less than 45 m, and the nickel-based alloy matrix or the cobalt-based alloy matrix comprising at least one metal carbide forming element.

A system for manufacturing of a sintered wire and in-situ feeding to a laser wire welding system is presented. The system includes a pressure vessel connected to a powder feed system for delivering at least two powders to a powder mixing zone of the pressure vessel. The at least two powders are mixed via a rotating cone in the pressure vessel. After mixing, a heating device contained within the pressure vessel heats the mixture so that liquid phase sintering occurs and a sintered rod is created. The sintered wire is continuously fed to a laser metal deposition system for depositing a layer of additive material on a base material. A method of additively manufacturing or repairing a superalloy component is also presented.

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 sliding part with a wear resistant coating includes a sliding part, and a wear resistant coating provided on a sliding surface of the sliding part, and made of a cobalt alloy containing chromium and silicon. In the wear resistant coating, oxide particles are dispersed which include an oxide containing chromium and silicon, and have a particle size of 100 m or less when a cross section of the wear resistant coating is observed using an optical microscope with a magnification of 100 times.

The present invention accurately distinguishes a soldering material less likely to oxidize. A Cu core ball has a Cu ball having a predetermined size, and a solder layer coating the Cu ball. The Cu ball provides a space between a semiconductor package and a printed circuit board. The Cu core ball has the soldering material having lightness greater than or equal to 62.5 in L*a*b* color space subsequent to a heating storage test performed for 72 hours in a temperature-controlled bath at 150 C. with a temperature of 25 C. and 40% humidity, and the soldering material, prior to the heating storage test, having lightness greater than or equal to 65 in the L*a*b* color space and yellowness less than or equal to 7.0 in the L*a*b* color space.

The disclosure describes techniques for joining a first component comprising a first metal or alloy and a second component comprising a second metal or alloy to each other. The techniques may include positioning the first and second component adjacent to each other to define a joint region between adjacent portions of the first component and the second component. The techniques also may include positioning a pre-sintered preform (PSP) braze material in the joint region, heating the PSP braze material to form a molten braze alloy, and cooling the molten braze alloy to join the first and second components. The PSP braze material may include a wide gap braze material.

A method for producing a sealing component has a body made of superalloy covered by a coating to be placed in contact with a gas turbine blade tip. Steps are carried out in which: a) the new coating is produced by moulding from an alloy of a cobalt-nickel-chromium-aluminium-yttrium (CoNiCrAlY) type further containing between 0.5 and 5% by mass (wt %) of boron, and b) the superalloy body and the new coating are brazed together in order to obtain the said sealing component.
