Abstract
The study covers transformation of the structure, phase and chemical composition in the Al–Ni and Al–Ni–Cr coatings obtained by the diffusion interaction under the heat treatment of the impact bonded 12Kh1MF+NP2+AD1 and 12Kh1MF+Kh20N80+AD1 laminated composites. It was found that increasing the hold time at 1100 °C leads to the stabilization of chemical composition in the surface coating accompanied by the increase of nickel and decrease of aluminium proportion. It was shown that redistribution of aluminium within the diffusion coating during the temperature impact is slower in the Al–Ni–Cr system than in the binary Al–Ni system.
