A sliding member having a sliding surface that is at least partially formed of a surface of a lubricating member is provided. The sliding member includes: a base body as a sintered body of a compact containing metal powder, the base body being integrated with the lubricating member; and the lubricating member as an injection molded product of a resin composition containing a polyarylene sulfide-based resin and a carbon material.

A method is disclosed for forming extrudate filament, which consist essentially of fiber, organic binder, and metal and/or ceramic. The extrudate filament can be spooled, or used to form preforms, and/or assemblages of preforms. In further methods, the extrudate filament and/or preforms can be used to fabricate fiber-reinforced metal-matrix or ceramic-matrix or metal and ceramic matrix composite parts, which consist essentially of fiber in a matrix of metal, or ceramic, or metal and ceramic, respectively.

The present disclosure relates to a wear part having high wear resistance and strength and a method of making the same. The wear part is composed of a compound body of cemented carbide particles cast with a low-carbon steel alloy. The low-carbon steel alloy has a carbon content corresponding to a carbon equivalent Ceq=wt % C+0.3(wt % Si+wt % P) of about 0.1 to about 1.5 weight %. The wear part could include a body with a plurality of inserts of cemented carbide particles cast into a low-carbon steel alloy disposed in the body. Each of the plurality of cemented carbide inserts are coated with at least one layer of oxidation protection/chemical resistant material. The plurality of inserts are directly fixed onto a mold corresponding to the shape of the wear part. The cemented carbide inserts are then encapsulated with the molten low-carbon steel alloy to cast the cemented carbide inserts with the low-carbon steel alloy.

A method for producing a component for a turbomachine, having the additive build-up of the component by an additive production method from a base material for the component and the introduction of material fibers into a construction for the component during the additive build-up in such a way that the material fibers are oriented in a circumferential direction of the component around a component axis and in such a way that a fiber composite material is produced, including the material fibers and a base material that is solidified by the additive build-up. A corresponding component is produced by the method and a corresponding device is used for producing the component.

A composite reinforcement insert includes a strand formed by a central fiber made of ceramic material surrounded by filaments of metal alloy helically wound around the central fiber, and a metal reinforcement layer covering the strand.
