Cladding of stainless steel on aluminum and carbon steel by interlayer diffusion bonding

An Al–Cu–Mg interlayer alloy is used in cladding the sheets of 304L stainless steel/L2Y2 aluminum alloy and 304L stainless steel/Q235A carbon steel. Effects of cladding temperature and time on the interfacial bonding of the two sheets are studied. Experimental results show that the Interfacial cohesion of the substrates and the clad stainless steel is closely related to the thickness of the diffusion layers in the substrates and the clad, and controlled by diffusion layer thickness in 304L side.
