Abstract:
A technique for using an iron plating for coating an aluminum product that results in adequate durability. An aluminum piston (l?) used as a plated aluminum product is covered by an iron-based composite plating layer (l l). The iron-based composite plating layer (ll) contains a carbon nanomaterial, which is applied to the aluminum-based base material using a iron-based composite plating bath formed by mixing a carbon nanomaterial into an iron plating bath.

Zur Lösung der Aufgabe, eine Ölpumpe zur Verfügung zu stellen, welche sowohl leicht als auch kompakt ist, wird eine Ölpumpe mit einem Gehäuse, hergestellt aus einem Aluminium umfassenden Material, und in dem Gehäuse angeordneten beweglichen Formteilen vorgeschlagen, wobei die beweglichen Formteile zumindest teilweise hergestellt sind aus einem sinterfähigen Material, umfassend mindestens eine austenitische Eisenbasislegierung, und wobei die aus dem sinterfähigen Material hergestellten beweglichen Formteile einen Wärmekoeffizienten aufweisen, welcher mindestens 60% desjenigen des Gehäuses beträgt.
Abstract:
Die Erfindung betrifft ein Druckguss-Zylinderkurbelgehäuse in dass eine Liner (4) aus mehreren Zylinderlaufbuchsen eingegossen ist. Der Liner (4) wird im Sandguss hergestellt und in das Druckgusswerkzeug eingelegt. Der Liner (4) weist einen zumindest teilweise geschlossenen Wassermantel (6) auf. Der Wassermantel (6) kann gegebenenfalls Kühlkanäle (10) im Stegbereich (12) umfassen.
Abstract:
A high-pressure fuel feed pump, wherein a pump housing is formed with an aluminum alloy, a cylinder is formed with an iron base metal, the flange part of a flanged tubular member is held in a contact part between the pump housing and the cylinder, and the tubular member is installed in the pump housing along the inner wall surface thereof, whereby a seal surface is not corroded directly because a cavitation occurs between the tip of the tubular member and the pump housing.
Abstract:
The present invention relates to an arrangement and a method for counteracting the occurrence of tensile stresses in at least one region (12-15) of an engine block (2), which engine block (2) incorporates at least one removable element. Such an element may be a main-bearing cap (9). Said element is intended, in a state whereby it is connected to the engine block (2), to create compressive stresses in said region (12-15). These compressive stresses will thus counteract tensile stresses which occur in the region during operation of the engine.
Abstract:
A plain bearing comprises a metal backing, a bearing lining formed from an alloy based on aluminium or on copper, and an overlay either directly plated on to the bearing lining, or plated on to an interlayer which is itself plated on to the bearing lining. The overlay comprises an alloy of zinc with 0.5 to 25 % by weight of a metal selected from nickel, cobalt and iron.
Abstract:
For a device for the breaking separation of bearing caps of aligned bearing bores in bearing systems of a part of an engine comprising a somewhat semicircular profiled separator guided and acting centrally on a bearing cap in the bearing bore, in order to achieve a simple structure, it is proposed that there be a half mandrel or full mandrel which can be axially arranged in one or more bearing bores and that an actuating rod system guiding the mandrel concerned only in the breaking separation direction engage with the mandrel concerned transversely to its longitudinal extension, whereby the mandrel concerned is held against rotation and each bearing cap is clamped against the mandrel concerned against rotation.
Abstract:
A swash plate 3 includes a substrate 11 made of an iron-based material, a hard first resin layer 12 provided to coat an end surface of the substrate 11, and a soft second resin layer 13 provided to coat the first resin layer 12. A spiral annular groove 12A is formed in a surface of the first resin layer 12, and the second resin layer 13 is provided to match the sectional shape of the first resin layer 12. With the soft second resin layer 13 on a sliding surface 3A of the swash plate 3, a swash plate 3 having a good fit in an initial stage of sliding can be provided. When the second resin layer 13 partially wears, a protrusion 12 of the first resin layer 12 of the hard resin is exposed to provide good wear resistance and good sliding properties.
Abstract:
In a method of plating aluminum based articles, an iron-based composite plating bath formed by admixing a nano-sized, particle-deposited carbon material into an iron plating bath at a ratio of 1.0 g per liter is provided. Using the iron-based composite plating bath, an iron-based composite plating layer containing the nano-sized, particle-deposited carbon material is plated on an aluminum-based base material.
