Presented basic mathematical dependences that describe the propagation of surface waves. As a result, the study found that the change of physical and mechanical properties of the surface of the plate surface velocity of ultrasonic waves is changed. The current model allows propagation of waves in detail aimed to analyze the wave field on the thickness of the pipe wall as a result of which you can choose the optimum frequency range for NDT. The structure of a mathematical model describing the spread of directed waves, takes into account the interaction of elastic oscillations of internal and external borders media division wall tubes - the environment that allows the development of methods to control the physical and chemical properties of the surface of the pipe wall, which includes the presence of passive film. Analyzed the nature of the process of oxide film on metal surface. The block diagram of a device for determining the magnetic susceptibility on the surface of the metal pattern.
