Abstract
A component composite includes a first component having a first contact surface and at least one second component having a second contact surface contacting the first contact surface, the first contact surface having a surface structure which has a microstructure which is superposed by a nanostructure, the contact of the second contact surface on the first contact surface taking place by at least partially melting the material of the second component, and the melting point of the material of the first component being higher than the melting point of the material of the second component.
Claims7
A component composite, comprising:
- a first component having a planar upper side comprising an indentation formed therein having a plurality of peripheral surfaces and a bottom surface defining a first contact surface, wherein the first contact surface has a surface structure having a microstructure which is superposed by a nanostructure;
- and
- a second component having two oblique front sides with an extension disposed therebetween, the extension defining a second contact surface, wherein the extension has a plurality of peripheral surfaces having the same cross-sectional geometry as the indentation and protrudes into the indentation to fill the indentation and form a form-locked connection with the peripheral surfaces of the indentation, and wherein the second contact surface contacts the first contact surface such that a wedge-shaped gap is situated between each of the two front sides and the planar upper side;
- wherein the contact of the second contact surface with the first contact surface takes place by heating the material of the second component to a temperature beyond its melting point only locally at a contact area of the extension with the indentation to at least partially melt the material of the extension at the second contact surface such that liquefied material of the second contact surface fills the surface structure of the first contact surface to create an adhesion between the second component and the first component at the first contact surface,
- wherein the second component is made of metal, and wherein the melting point of a material of the first component is higher than the melting point of the material of the second component.
A method for manufacturing a component composite, the method comprising:
- providing a first component having a planar upper side comprising an indentation formed therein having a plurality of peripheral surfaces and a bottom surface defining a first contact surface, wherein the first contact surface has a surface structure having a microstructure which is superposed by a nanostructure;
- providing a second component having two oblique front sides with an extension disposed therebetween, the extension defining a second contact surface, wherein the extension has a plurality of peripheral surfaces having the same cross-sectional geometry as the indentation and protrudes into the indentation to fill the indentation and form a form-locked connection with the peripheral surfaces of the indentation, wherein the second contact surface contacts the first contact surface such that a wedge-shaped gap is situated between each of the two front sides and the planar upper side, wherein the second component is made of metal, and wherein the melting point of the material of the first component is higher than the melting point of the material of the second component;
- and
- heating a material of the second component to a temperature beyond its melting point for the purpose of contacting the first component, wherein the heating of the material of the second component to beyond its melting point takes place only locally at a contact area of the extension with the indentation;
- wherein the contact of the second contact surface with the first contact surface takes place by at least partially melting the material of the extension at the second contact surface such that liquefied material of the second contact surface fills the surface structure of the first contact surface to create an adhesion between the second component and the first component at the first contact surface.
