A friction brake body for a friction brake of a motor vehicle, in particular a brake disk, includes a base body made in particular from gray cast iron and having at least one wear resistant layer formed on a friction contact surface of the base body. The wear resistant layer is made from ferritic-austenitic steel and includes an incorporated hard material particle, in particular finely distributed hard material particle.

A joined assembly includes: a first member; a second member which has a facing part facing the first member in a thickness direction thereof; and joints lying along the facing part to join the first member and the second member to each other. The joints include: a pair of end joints respectively located at the opposite end portions of the facing part; and an intermediate joint located between the end joints and having a lower joining strength than the end joints. The end joint includes a fastening member mechanically joining the first member and the second member. The intermediate joint includes a friction-stirred part joining the first member and the second member by friction stir.

A light guide device includes a first light guide part, a polygon mirror, and a second light guide part. The first part reflects and guides a laser light emitted from a laser generator. The polygon mirror rotates and includes reflective parts. The reflective parts are arranged to form a regular polygonal reflective surface when viewed in a rotation axis direction, the polygon mirror reflecting the light guided by the first part by the reflective part while rotating. The second part reflects the light reflected at the reflective part and guides the light so that the light is irradiated to the workpiece at each of the reflective parts. The reflective part reflects the incident light so that the optical axis of the incident light offset in the rotation axis direction. At least two reflective parts differ from each other in position in the rotation axis direction.

A method for bonding components is disclosed. The method may comprise positioning an interlayer between a metallic component and a metal-plated non-metallic component at a bond region, heating the bond region to a bonding temperature to produce a liquid at the bond region, and maintaining the bond region at the bonding temperature until the liquid has solidified to form a bond between the metallic component and the metal-plated non-metallic component at the bond region. A method for providing a part having a customized coating is also disclosed. The method may comprise applying a metallic coating on a surface of a metallic substrate, and bonding the metallic coating to the metallic substrate by a transient liquid phase bonding process to provide the part having the customized coating.

A fastener feed apparatus includes a mounting portion and a feed portion attached movably thereto. The feed portion includes a feed body having first and second ends and an internal track extending therethrough. The internal track is sized and shaped to convey a fastener through the feed body. The feed portion also includes a feeding block attached to the second end of the feed body and including a body and a pair of feed fingers, each of which includes a first end attached to the body and a second end. A track is formed between the feed fingers, is sized and shaped to convey the fastener from its first end to its second end, and is contiguous with the internal track of the feed body. The second end of the track includes a retention point. The feed fingers are sized and shaped to retain the fastener at the retention point.

An apparatus for fabricating a part, comprising a curved shaft; a build plate connected to the curved shaft; a motor; and a transmission connecting the motor and the curved shaft. The build plate moves along a curved path having a radius of curvature originating on an axis when the transmission transfers power from the motor to the curved shaft. Material deposited on the build plate along the curved path forms the part comprising a solid of revolution around the axis. In one or more examples, the part is an aircraft engine inlet.

Methods for welding a particle-matrix composite body to another body and repairing particle-matrix composite bodies are disclosed. Additionally, earth-boring tools having a joint that includes an overlapping root portion and a weld groove having a face portion with a first bevel portion and a second bevel portion are disclosed. In some embodiments, a particle-matrix bit body of an earth-boring tool may be repaired by removing a damaged portion, heating the particle-matrix composite bit body, and forming a built-up metallic structure thereon. In other embodiments, a particle-matrix composite body may be welded to a metallic body by forming a joint, heating the particle-matrix composite body, melting a metallic filler material forming a weld bead and cooling the welded particle-matrix composite body, metallic filler material and metallic body at a controlled rate.

On at least the edge portion (9e) of the lip portion (9) of a T-die (1), a cladding layer (10) is provided. The cladding layer is formed by laser build-up welding to a base material with a powder of a corrosion resistant and wear resistant alloy comprising a nickel-based alloy or a cobalt-based alloy. The cladding layer has a metallographic structure in which metal borides are dispersed in a binder phase. The lip portion has high quality and has high durability. The manufacturing costs of the T-die can also be kept relatively low.

By surface roughening of CMC component via a pico-laser treatment a good adhering of a plasma sprayed coating is achieved.
