- the compound is produced in a single friction welding process.
- This procedure has the advantage that only a single friction welding process has to be carried out.
- the connector is not firmly attached before the friction welding either on the steel part or on the component so dasa the friction welding process can not cause any thermal or mechanical stress on a previously introduced in the vicinity of the compound connection or joint.
- the combination of two friction welding processes for connecting the intermediate piece first with a steel part and then with the titanium aluminide component leads to an impairment of the first friction-welding intermediate layer or connecting layer.
- the method according to the invention thus has the advantage that a comparatively thin intermediate layer can be chosen for the connection of the two workpieces.
- the connecting layer must be chosen only so thick that a material and form-fitting connection can be formed.
- the connection layer is preferably designed somewhat thicker, so that it acts as a thermal barrier, that is to say an obstacle to the heat conduction. This is particularly important if the second component is made of steel or a titanium alloy with a lower melting point than the metal aluminide alloy of the first component,
- the intermediate piece. (4) preferably has a thickness in the range of 1 to 10 mm.
- the thickness of the spacer is significantly reduced by pushing the excess material laterally out of the joint area.

These diffusion zones or mixing zones represent an effective cohesive connection.
- connection layer may have a penetration structure of the three metal alloys involved.
- the one-step friction welding process must be performed at temperatures that correspond to the friction welding temperatures of the higher melting point metal aluminides.
- the high temperatures lead to a very effective two-sided welding of the intermediate piece.
- Suitable metal aluminides include titanium aluminide, nickel aluminide, or iron aluminide.
- a nickel alloy in particular a nickel-based alloy is selected.
- a nickel-based alloy is selected.
- the Ni alloy is formed by a Ni-base alloy and embedded ceramic particles.
- Preferred ceramic particles are SiC, TiC and / or WC. The ceramic particles have the effect of friction particles, which have a favorable effect on the friction welding process. In the bonding layer, the ceramic particles in particular bring about an advantageous reduction in the thermal conductivity or the heat transfer.
- the intermediate piece can be designed as a plate, foil or cap, which is introduced between the Verbind.ungs Scheme before friction welding or loosely attached to one of the two bodies. It is also possible to connect the thus designed intermediate piece with one of the two bodies mechanically or positively, for example by pressing or shrinking. It is expedient to be guided by the more suitable geometry of the two components to be connected.
- a recess in the connecting region is provided on one of the two bodies, in which the intermediate piece, in particular as
- a further preferred embodiment of the method is shown schematically in FIG. 4 and provides that the Intermediate piece in a feed device (9), in particular one fixed to a belt (7) is fed continuously into the connecting region of the two components.

- components (1, 2) bars of titanium aluminide can be provided, for example, on both sides.
- the components (1, 2) are held by movable clamping and are friction welded to the connector. (4) ascended. After friction welding, the steel strip (7) is separated from the welded-together component, whereby the component can be removed from the dex friction welding device.
- the steel strip is moved further into the connecting region by means of the sender (9) and brought into position with newly clamped components (1, 3).
- different rotational speeds and pressure strengths during friction welding can be provided by the two components (1) or (2) in order to produce different welding temperatures or welding pressures on the two sides of the intermediate piece.
- the intermediate piece is not loosely introduced into the connection area, but first positively connected to one of the components. If a steel part is provided, this is usually the preferred partner for attachment of the intermediate piece.
- the compound itself need not have any particular strength, since it only has to ensure the fixation of the intermediate piece for the friction welding process. Therefore, quite different methods for fastening the intermediate piece can be used. In particular, in this case it is not necessary to fasten the connecting piece by welding or friction welding.
- the intermediate piece consists of a coating of a Ni alloy.
- Ni, nickel alloy or a Ni alloy with SiC particles can be electrodeposited.
- the steel part is coated, in particular galvanically coated.
- the coating consists of a pressed-on powder push, in particular of Ni alloy with ceramic particles and / or further metal particles, in particular of Cr, Sb or Mo.
- At least one of the two components, steel part or metal aluminide component, is rotationally symmetrical.
- the first component is a steel rod or a steel cylinder, which is connected to the second component.
- the friction welding preferably forms a rotationally symmetrical body with a longitudinal axis in the steel part. It is obvious that the invention 006/002786
