A method of manufacturing a strip for a bearing may comprise roll-bonding a bearing layer comprising a tin-free aluminium alloy directly to a base layer to form a bimetal and heat-treating the bimetal at a temperature below a recrystallization initiation temperature of the aluminium alloy. A strip for a bearing manufactured using the method, and a bearing having a strip manufactured using the method, are also provided.

Method of manufacturing a strip for a bearing

A valve for an internal-combustion engine may include a body. The body may include a titanium alloy. At least one region of the body may include a nitrided layer. The nitrided layer may include at least one of titanium nitrides and aluminium-titanium nitrides.

Valve for internal-combustion engines

A wet cylinder liner for internal combustion engines may include a cylindrical body composed of a ferrous alloy having a circumferential outer surface. The cylindrical body may include a first layer and a second layer disposed sequentially on the outer surface. The first layer may include at least one of at least one silicon and at least one two-component epoxy adhesive. The second layer may include a silane-elastomer compound. The silane-elastomer compound may include nanoparticles of silicon oxide and an adhesion modifier additive. The second layer may be configured as an interface between a cooling fluid and the first layer, as well as to resist erosion by cavitation. The first layer may facilitate an interface for resistance at high temperatures.

A bearing for an internal combustion engine may include a steel support layer. A coating layer containing a Cu alloy may be laid over the steel support layer. A Ni-based anti-diffusion barrier layer may be laid over the coating layer, and an anti-friction layer containing a matrix of Sn&#x2014;Zn and Zn precipitates may be laid over the anti-diffusion barrier layer.

Bearing for internal combustion engines

A bearing may include a substrate and a metallic layer disposed in contact with the substrate. An adhesive layer may be disposed in contact with the metallic layer. A supporting layer may be disposed in contact with the adhesive layer. According to an example, a polymer layer may be disposed in contact with the adhesive layer. According to another example, a polymer layer may be disposed in contact with the supporting layer.

Bearing and connecting rod

A piston ring may include a metallic base, an outer slide layer and an intermediate layer disposed between the base and the outer slide layer. The base may extend between at least two end regions. The outer slide layer and the intermediate layer may be disposed on an outer radial face of each end region of the base.

Piston ring

A valve for an internal combustion engine may include a ferrous body having a neck. At least one area of the neck may include a surface layer with a thickness of up to 300 &#x3bc;m. The valve may also be provided with at least 17% solubilized metallic chromium, which may be obtained by an application of a surface melting treatment.

Valve for internal combustion engines and method for obtaining a valve

A piston for an internal combustion engine may include a substantially circular body composed of an aluminum containing base material defining a top portion having at least one cavity. At least one coating layer may be disposed on at least one area defined by at least one of the top portion and the at least one cavity. The at least one coating layer may include at least one chemical compound derived from a chemical reaction between the base material of the body and the at least one coating layer in response to friction generated by a dragging movement of a non-consumable rotary pin with the at least one coating layer.
