A powder metal alloy composition is used in the production of a sintered powder metal insert for casting into an aluminum casting. The powder metal alloy composition includes an iron powder metal base, copper such that the copper is 3.5 weight percent or more of the powder metal alloy composition, and carbon in an amount of 0.1 to 1.0 weight percent of the powder metal alloy composition. Upon compacting and sintering the powder metal alloy composition to form the sintered powder metal insert, the sintered powder metal insert has a copper gradient that provides a higher concentration of copper on the surface of the sintered powder metal insert than in a center of the grains of the sintered powder metal insert. The higher concentration of copper at the surface of the insert enables a strong metallurgical bond to be formed with the aluminum casting during casting.

A method for manufacturing a tube body made of fiber-reinforced plastic and used in a power transmission shaft is provided and the method includes: a generating step of disposing an uncured fiber-reinforced resin on a cavity surface of a mold and generating a resin body in a cylindrical shape; and a curing step of supplying a fluid inside the resin body and curing the resin of the resin body.

A steering gearbox is equipped with a casing, a rack shaft, and a plurality of bushes. The rack shaft is accommodated in a casing to be movable in an axial direction. The plurality of bushes support the rack shaft to be movable in the axial direction and are attached to the casing.

Methods for making a tribological bearing wear surface for a compressor component are provided. Such methods involve semi-solid metal casting, where an admixture of solid lubricant particles and a metal alloy material is heated to melt the metal alloy material, while the lubricant particles remain in a solid phase. The alloy material and solid lubricant have substantially different densities. The metal alloy material may be a copper, iron, or aluminum alloy, for example. The method further comprises mixing and cooling the admixture to form a semi-solid slurry admixture. Next, the method comprises introducing the semi-solid slurry admixture into a die. Finally, the semi-solid slurry admixture in the die is solidified to form a solid component having the solid lubricant particles homogenously distributed within a metal alloy material matrix, thus forming a metal matrix composite. Compressor components made from such methods are also provided.

A bearing bushing (1) and to a method for manufacturing a bearing bushing are provided. The bearing bushing includes a wire article (2) formed from knitted wire mesh or knitted wire fabric (6) and compressed into a dimensionally stable compressed product (3). The bearing bushing can be provided for supporting a throttle valve used in high-temperature applications. The wire article (2) is formed from a stainless steel. Existing voids (10) of the compressed product (3) are filled with solder (4).

Provided is a sliding member capable of realizing the wear resistance effect by Si particles. The sliding member includes an aluminum alloy layer containing 7.0% by mass or more and 13.0% by mass or less of Sn, 6.5% by mass or more and 12.0% by mass or less of Si, 0.5% by mass or more and 3.0% by mass or less of Cu, unavoidable impurities, and a balance Al. Si particles are dispersed in the aluminum alloy layer. A Vickers hardness of a matrix of the aluminum alloy layer is 40 HV or more and 60 HV or less. A load resistance value, which is a product of a volume concentration and average area of the Si particles and the Vickers hardness of the matrix, is 0.00001 N or more and 0.00029 N or less.
