Dispersion curves of a system consisting of a piezoelectric covering layer and metal half-plane under the uniaxial initial stresses perpendicular to the wave propagation direction are obtained within the scope of the Three-dimensional Linearized Theory of Elastic Waves in Initially Stressed Bodies. The elasticity relations of the metal half-plane material are described by the Murnaghan potential. The numerical results are discussed for PZT-2 covering layer and aluminum half-plane material. The influence of the initial stresses, the piezoelectricity of the covering layer, and the third order elastic constants on the near-surface wave propagation velocity is illustrated.
