Abstract
First and second components 2, 4, which may be metallic components, are joined together in a process which comprises introducing a sinterable powder 20 between the components, the powder being retained within a receptacle 16, displacing the component 4 towards the component 2 to compress the powder, and subsequently applying heat and pressure to the powder 20 to form a sintered bond.
Claims17
A method of joining first and second components comprising:
- (a) placing a containment device in contact with the first component so that a faying surface of the first component is exposed to the interior of the containment device;
- (b) introducing a sinterable powder into the containment device so that the sinterable powder accumulates on the faying surface of the first component;
- (c) fluidising the sinterable powder;
- (d) displacing the first and second components relatively to each other to move a faying surface of the second component and the faying surface of the first component towards each other within the containment device, thereby to compress the fluidised powder in a bonding region between the faying surfaces of the first and second components;
- and
- (e) performing a consolidation process on the compressed powder to consolidate the powder in the bonding region to form a joint between the components.
