24. Acoustically Driven Piezoelectric Antenna for VLF Transmission and Reception

Author

Abstract

A portable piezoelectric antenna array for both very low-frequency (VLF) transmitting and receiving is proposed, based on piezoelectric lead zirconate titanate ceramics with the size of ∼10 cm, being 1/105 of the wavelength. Piezoelectric antennas with plane electrodes show a large electromechanical coupling coefficient, leading to stronger mechanical vibration, which results in an enhanced radiation. For a pair of piezoelectric antennas, the measured radiation pattern is well consistent with the prediction and the maximum radiation capability of 80 m has been attained. Moreover, a linear increase in receiving signal amplitude with the number of elements in the transmitting antenna array has been proved. Binary amplitude shift keying modulation up to 800 bits/s has been successfully demonstrated on a pair of piezoelectric antennas. These results suggest that acoustically driven piezoelectric antennas have great potential for long-distance VLF communication by scaling up the piezoelectric antenna array.

Abstract

The oxidation resistance of TiAl alloys is crucial for their commercial application. In this paper, a cyclic oxidation test with stable air circulation was designed to investigate the cyclic oxidation behavior of the TNM alloy and 4822 alloy at 800 °C and to analyze the phase, morphology, and thermal stress evolution of the oxide layer. The oxidation weight gain curves of both alloys are found to be in parabolic form, and the oxidation reaction orders of the TNM alloy and 4822 alloy are 2.374 and 1.838, respectively. The Nb and Mo elements enhance the antioxidant performance of the TNM alloy by inhibiting the dissolution and diffusion of oxygen, Ti, and Al atoms in the TiAl alloy. The thermal stress evolution of the two alloys during the heating and cooling phases of the cyclic oxidation process are calculated separately, and it is found that the thermal stresses in the TNM alloy are smaller than those in the 4822 alloy, while the maximum thermal stresses appear at the oxide/substrate interface rather than inside the oxide scale, which quantitatively explains the oxidation peeling resistance of the two alloys.
