The present application relates to a method for the production of an engine component, in particular a piston for an internal combustion engine, in which an aluminum alloy is cast in a diecasting process. The aluminum alloy comprises the following alloy elements: silicon: 6 to 10 % by weight; nickel: 1.2 to 2 % by weight; copper: 8 to 10 % by weight; magnesium: 0.5 to 1.5 % by weight; iron: 0.6 to 1.5 % by weight; manganese: 0.2 to 0.4 % by weight; zirconium: 0.2 to 0.5 % by weight; vanadium: 0.1 to 0.3 % by weight; titanium: 0.1 to 0.5 % by weight, the aluminum alloy otherwise comprising aluminum and unavoidable contaminants.
Abstract:
The holder has a fastening section (2) for fastening the holder at a load arm (1) of a tribometer. A support element (3) is freely rotatable around an axis of rotation and directly forms a support together with the fastening section and a counter body segment (4), such that the counter body segment is tiltable relative to the fastening section. The support element has a roller body i.e. ball, which forms a ball and socket joint together with the fastening section and the counter body segment. Independent claims are also included for the following: (1) a measuring arrangement for measuring friction and wear characteristics comprising a tribometer and a sample holder (2) a method for measuring friction and wear characteristics.
Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung von wasserlöslichen Salzkernen zur Ausbildung von Hohlformen in Gießverfahren. Das Verfahren zeichnet sich dadurch aus, dass den Salzkernen ein Metallpulver zugesetzt wird, über welches der Salzkern mittels magnetischer Induktion erhitzt und getrocknet wird. Hierbei ist entscheidend, dass das Metallpulver in dem für die Trocknung gewünschten Temperaturbereich ferromagnetische Eigenschaften hat.
