摘要：
Problems of providing uniformity of measurements of the thickness of metallic coatings by the eddy-current phase method are examined. The physical principles of the method as well as the design and metrological characteristics of the measuring instruments are analyzed. The dependences of the error of measuring the thickness of metallic coatings on the influencing parameters during graduation, verification, and calibration are obtained. The requirements imposed on the electrophysical parameters of metallic coating thickness standards are formulated.
