Abstract
The influence of critical corners of longitudinal and transversal waves propagation on reliability of measurements in the non-destructive method of adhesion control of cast-iron coverages is described. The article considers superficial Love and Rayleigh waves that are formed during the transformation of the longitudinal wave in the sample of metal on which applied a thin solid coating. The model of distribution of surface waves is expounded for gas-thermal chromic coverage in a 0,35 – 0,55 mm thick on cast-iron. The accuracy of the above approach is confirmed by a standardized method of mechanical separation on a tensile testing machine. The errors of determination of adhesion of coverage are appraised.
