The paper considers the importance of developing a complex technology of high energy effect on the components of composite materials in their manufacture. The paper proves that the most promising technology is the one based on the use of explosion welding and micro-arc oxidation, providing the specified composite material structure and properties. The major advantages of explosion welding for producing composite metallic materials, compared to other methods of composite manufacture, are presented. Under the action of impact waves, materials significantly increase their durability, strength, toughness and fatigue resistance. The characteristic of micro-arc oxidation technology used for producing multi-functional composite materials featuring a wide range of properties including wear resistance, corrosion resistance, heat resistance, electrical insulation properties, decorativeness and their unique combination is given. In comparison with such methods as thermal, chemical and electrochemical oxidation, micro-arc oxidation is the most promising, because it allows the oxide-ceramic coatings of any thickness, without any restrictions for the purpose intended and in any stage of processing.
Keywords: composite material, a high-energy impact, explosion welding, micro-arc oxidation, mechanical and thermal properties.

A scheme is proposed, in which the locations of the noise sources, special housings with ferroelectric ceramics coating that through direct and inverse piezoelectric record an acoustic signal with built-in microprocessor analyzes it and generates a response in anti-acoustic wave. As the technology of coatings applied ferroelectric ceramics gas-dynamic spraying. In this paper the dependence of the acoustic power of the change in the area of the electrode surface and the polarization voltage. To increase the effectiveness of noise reduction of working arrangements, where their amplitude – frequency characteristics are very different from each other, including the width of the preferred frequencies proposed multicell design ferroelectric ceramics layer.
Keywords: piezoelectric effect, acoustic power, frequency response, resonance frequency.

This article shows the change in the basic properties of piezoelectric composite polymers depending on the nature of the distribution of the filler in the polymer matrix. Considered ten classes of composites with different types of connectivity of the filler to the polymer. Based on the theoretical analysis of the simplest of these composites are polymers with randomly distributed particles in it ceramic ball shape, is a model of piezoelectric and mechanical properties of the polymer-ceramic composite piezoelectrics. The theoretical dependence of the volume content piezo sensitivity ceramics for various types of composites. The basic concepts, principles and laws of the process gas dynamic spraying of powder materials, shows the stages of the process gas dynamic spraying. Are the main advantages and disadvantages of the gas-dynamic spraying using charge material with high density and low flowability.
Keywords: piezoelectric, composite, polymer, gas-dynamic spraying.
