Conclusions
-
1.
The experimental and metrological characteristics of an ultrasonic delay line are affected substantially by the micro- and macrogeometry of its surface.
-
2.
The parameters adopted for evaluating the roughness of a surface (Ra, Rz, Hck) do not provide an adequate characteristic of its microgeometry.
-
3.
Correlation analysis provides the possibility of obtaining a more complete judgement on the microrelief of prism surfaces from the point of view of their metrological possibilities and operational properties.
