The applicability of the method to control eddy currents duralumin sample with a curved surface shape. It was shown the possibility of reducing the negative impact of the gap between the sensor and the surface of the material in the diagnosis of aluminum alloys with different heat treatment. The role of the factors that make it difficult diagnosis compared with the case of a flat surface. It was founded the feature in dependence of the eddy currents field response on the structural state of the aluminum alloy and the gap between the field source and the test material. The proposed method allows to take into account the influence of random factors that distort the measurement result, for example, in the diagnosis of aluminum alloy products with a curved surface. It proposed usage for the control of heat treatment of aluminum alloys approach based on multivariate analysis of informative parameters of eddy current diagnostics.
