The aluminium matrix composites were prepared by HVOF spraying of nickel and nickel with 20wt.% chromium powders onto the aluminium sheet s surface followed by annealing at the temperature 600oC and 63oC. Immediately after the annealing was the composites rapidly cooled by fan down to the room temperature. At the interface between the original coating sprayed and aluminium matrix and produce stenghtening by stable Al3Ni and metastable Al9Ni2 particles. It seems that the origin of the less koown metastable Al9Ni2 phase also depends on fast cooling rate. The microstructures were obtained by scanning electron microscope and transmission electron microscope. Layers and Al+(Al3Ni + Al9Ni2) band thickness measurements were realized by means of image analyses. Chemical composition were estimated by energy dispersive microanalysis. Qualitative and quantitative x-ray diffraction was used for determination of phases.
