The invention relates to a method for producing an engine component, in particular a piston for an internal combustion engine, wherein an aluminum alloy is cast in the gravity die casting process and wherein the aluminum alloy has 7 to &#x3c;14.5 wt % silicon, &#x3e;1.2 to &#x2264;4 wt % nickel, &#x3e;3.7 to &#x3c;10 wt % copper, &#x3c;1 wt % cobalt, 0.1 to 1.5 wt % magnesium, 0.1 to &#x2264;0.7 wt % iron, 0.1 to &#x2264;0.7 wt % manganese, &#x3e;0.1 to &#x3c;0.5 wt % zirconium, &#x2265;0.1 to &#x2264;0.3 wt % vanadium, 0.05 to 0.5 wt % titanium, and 0.004 to &#x2264;0.05 wt % phosphorus as alloying elements and aluminum and unavoidable contaminants as the remainder. The aluminum alloy can optionally comprise beryllium, wherein the calcium content is limited to a low level. The invention further relates to an engine component, in particular a piston for an internal combustion engine, wherein the engine component is composed at least partially of an aluminum alloy, and to the use of an aluminum alloy to produce an engine component, in particular a piston of an internal combustion engine.

Method for producing an engine component, engine component, and use of an aluminum alloy

In a method for producing a piston () for an internal combustion engine, a melt treatment is performed at least in regions in particular in the region of a combustion chamber depression (), the depth of said melt treatment being varied in the circumferential direction.

Method for producing a piston for an internal combustion engine

A method for producing an engine component, more particularly a piston for an internal combustion engine, in which an aluminum alloy is cast using the gravity die casting method is provided. The aluminum alloy comprises: 9 to &#x2264;10.5% by weight silicon, &#x3e;2.0 to &#x3c;3.5% by weight nickel, &#x3e;3.7 to 5.2% by weight copper, &#x3c;1% by weight cobalt, 0.5 to 1.5% by weight magnesium, 0.1 to 0.7% by weight iron, 0.1 to 0.4% by weight manganese, &#x3e;0.1 to &#x3c;0.2% by weight zirconium, &#x3e;0.1 to &#x3c;0.2% by weight vanadium, 0.05 to &#x3c;0.2% by weight titanium, 0.004 to 0.008% by weight phosphorus, with aluminum and unavoidable impurities constituting the rest. An engine component, in particular a piston, wherein the engine component consists, at least partially, of the aluminum alloy, and the use of an aluminum alloy to produce the engine component, is also provided.

A method is described for producing an engine component, more particularly a piston for an internal combustion engine, in which an aluminium alloy is cast using the gravity die casting method and wherein the aluminium alloy comprises the following alloy elements: 9 to &#x2264;10.5% by weight silicon, &#x3e;2.0 to &#x3c;3.5% by weight nickel, &#x3e;3.7 to 5.2% by weight copper, &#x3c;1% by weight cobalt, 0.5 to 1.5% by weight magnesium, 0.1 to 0.7% by weight iron, 0.1 to 0.4% by weight manganese, &#x3e;0.1 to &#x3c;0.2% by weight zirconium, &#x3e;0.1 to &#x3c;0.2% by weight vanadium, 0.05 to &#x3c;0.2% by weight titanium, 0.004 to 0.008% by weight phosphorus, wherein said aluminium alloy further comprises aluminium and unavoidable impurities. The invention further describes an engine component, in particular a piston for an internal combustion engine, wherein the engine component consists, at least partially, of an aluminium alloy, and the use of an aluminium alloy to produce an engine component, more particularly a piston of an internal combination engine.

In a process for producing a piston for an internal combustion engine, a groove is worked into a cast piston blank proceeding from a combustion chamber cavity () in a largely radial direction and then closed to form a cooling duct. A cast piston for an internal combustion engine has a closure which is fitted after the casting and the machining between the cooling duct and a combustion chamber cavity ().

Process for producing a piston for an internal combustion engine and piston for an internal combustion engine

The invention relates to a method for producing a piston for an internal combustion engine, wherein a section which in the finished piston has a cooling duct () and a piston ring groove is recessed at first, the later cooling duct is then covered, and finally material for accommodating the piston ring is applied, and which is characterized in that the later cooling duct is covered by a wire material which is provided in a length, greater than necessary for one single piston. A device for producing a piston for an internal combustion engine with an at first recessed section that in the finished piston has a cooling duct () and a piston ring groove, has a device for attaching a cover on the cooling duct and a device for providing wire material having a length greater than necessary for one single piston. A piston for an internal combustion engine has a cooling duct () and a reinforcement material for accommodating a piston ring as well as a cover material between the cooling duct () and the reinforcement material, wherein the cover material is made of wire material continuously unwinding from a roll.
