Abstract
A structural part includes a pocket where the pocket is formed during or after a production of the structural part. A coating material is disposed in the pocket where the coating material at least partially fills the pocket. A method for producing a structural part includes removing or reducing material in a portion of a structural part to produce or form a pocket during or after a forming of the structural part and filling the pocket with a coating material by a coating method.
Claims5
An aluminium die-cast structural part of a motor vehicle, comprising:
- a pocket, wherein the pocket is formed during a casting of the aluminium die-cast structural part, wherein the pocket is defined entirely within peripheral walls formed by the aluminium die-cast structural part and a base formed by the aluminium die-cast structural part, and wherein the base is inclined toward a surface of the aluminium die-cast structural part such that there is no abrupt change in stiffness in the aluminium die-cast structural part;
- a coating material disposed in the pocket, wherein the coating material at least partially fills the pocket and wherein the coating material is an iron-based material and wherein the coating material is disposed by cold gas spraying;
- and
- a further structural part of the motor vehicle, wherein the further structural part of the motor vehicle is fastened to the iron-based coating material that is disposed in the pocket by a weld or an adhesive bond or a rivet or a screw.
