The influence of the technology of deposition of a surface layer on the structure of the diffusion zone and the adhesion strength of functional-gradient layered steel–aluminum composites has been investigated. The compositions made by arc cladding with complete melting of an explosion-welded intermediate aluminum layer are shown to be characterized by a continuous layer of ternary Fe–Al–Si intermetallic compounds with an average thickness of 10 μm and to have an adhesion strength of 43 MPa. The technology of arc cladding with partial melting of the intermediate explosion-welded aluminum layer is found to fabricate compositions with a discrete layer of Fe–Al intermetallic compounds with an average thickness of 17 μm and an adhesion strength of 66 MPa.
