In this paper, the influence of positive and negative voltages to the formation process of ceramic coating on aluminum alloy was studied. The result indicates that, increasing of positive or negative voltage is favorable to the thickness increase and uniformity of the ceramic coating, the thickness of ceramic coating is linear correlation to the positive electrical quantity which is relative to loaded voltages. The ceramic coating is composed of α-Al2O3, γ-Al2O3 and mullite phases, and the voltages, especially negative voltage can increase the mass fraction of α-Al2O3 phase in the outer side of ceramic coating. The effects of voltage parameters on surface morphology of ceramic coating, thickness of ceramic coating and phase composition of ceramic coating is evident, in which the positive voltage is a decisive factor and the negative voltage is an important assistant factor.

Alloy Microstructure

The polyphase eutectics (α-Al+intermetallic+Si) constituting the final aluminum alloy microstructure were characterized by their phase composition, growth mechanism, and morphology of eutectic crystals. The main groups of eutectic phase constituents were presented with a special attention paid to intermetallic phases. Morphology of different types of polyphase eutectics, among those divorced, was characterized and presented (as microscopic images) on microphotographs. The microstructural effects of stable and metastable phases competition in the stage of nucleation and growth of polyphase eutectics as affected by local cooling rate and liquid alloy composition were described. Some examples of the evolution of the phase composition of eutectics in commercial alloys due to modifications of technological procedures were presented.
