Abstract
A casting component, in particular for a combustion engine of a motor vehicle, having at least one cavity formed by a lost casting core, where a porous metal body molded in the cavity is formed by the casting core, is disclosed. Furthermore, the casting core for such a casting component is formed by casting a metal, in particular an aluminum alloy, together with a salt. Finally, a method for the production of such a casting component or of such a casting core is also disclosed.
Claims6
A casting component of a combustion engine of a motor vehicle, comprising:
- a casting material;
- and
- a lost casting core including a metal and a salt disposed within the casting material, wherein the salt is dissolvable out from the lost casting core to form a porous metal body from the metal in the casting component.
A casting component of a combustion engine of a motor vehicle, comprising:
- a cavity formed by a lost casting core;
- wherein the lost casting core is a molded casting core including a metal and a salt and wherein the molded casting core forms a porous metal body in the cavity;
- wherein the porous metal body and the casting component are formed from materials having same properties.
A method for producing a casting component of a combustion engine of a motor vehicle, comprising the steps of:
- inserting a lost casting core into a casting tool;
- molding the lost casting core at least partially into a casting material of the casting component;
- wherein the lost casting core is a molded casting core including a metal and a salt;
- and
- dissolving the salt out from the molded casting core to form a porous metal body in the casting component.
