Titanium aluminium component

Abstract

A joining of a titanium material with an aluminium material, wherein the parts made of the two substances are connected with each other in a substance-to-substance manner. Preferably, the joining is effected by a laser beam or an electron beam.

1 . A component, comprising:
 a first region consisting of a titanium material; and   a second region consisting of an aluminium material;   wherein the first region and the second region are connected with a substance-to-substance bond; and   wherein the substance-to-substance bond is formed with a deep welding or with a heat conducting welding in the aluminium material of the second region in combination with a diffusion process with a heat flow from the aluminium material towards the titanium material of the first region;   wherein the component is a seat rail for an airplane seat and wherein the substance-to-substance bond is homogenous.   
   
   
       2 . The component of  claim 1 ,
 wherein the first and the second regions are connected with the substance-to-substance bond which is further formed with a heat conducting welding process in the aluminium material of the second region; and   wherein the diffusion process is initiated with a heat flow towards the titanium material of the first region.   
   
   
       3 . (canceled) 
   
   
       4 . The component of  claim 1 , further comprising:
 a web;   a thickening; and   a groove;   wherein the first region includes the web; and   wherein the second region includes the thickening with the groove for receiving the web.   
   
   
       5 . A method of joining a first region consisting of a titanium material and a second region consisting of a first aluminium material for manufacturing a component, the first region having a first area and the second region having a second area, wherein the first and second areas are to be connected with each other, wherein the method comprises:
 arranging the first area and the second area adjacent to one another;   melting-on a second aluminium material at the first area by supplying heat;   activating a surface in the first area of the first region by supplying heat; and   wherein the heat supply is such that the melted-on second aluminium material wets the activated titanium material and the substance-to-substance bond between the first region and the second region is formed by means of diffusion.   
   
   
       6 . The method of  claim 5 ,
 wherein the second aluminium material is the first aluminium material of the second region.   
   
   
       7 . The method of  claim 5 , further comprising:
 applying the heat supply to the first area of the first region and the second area of the second region.   
   
   
       8 . The method of  claim 5 , further comprising:
 applying the heat supply to the second area of the second region.   
   
   
       9 . The method of  claim 5 , further comprising:
 supplying the heat by means of a defocused laser beam or electron beam; and   supplying an inert gas.   
   
   
       10 . The method of  claim 5 , further comprising:
 providing a web in the first area of the first region;   providing a groove in the second area of the second region;   inserting the web into the groove;   providing a thickening comprising the second aluminium material in the second region; and   wherein the thickening is provided as material pool, for joining the first and second regions.
