METHOD FOR DETERMINING THE ROUGHNESS OF AN INTERNAL SURFACE

A method for determining the roughness of an internal surface of a metal substrate or a metal layer is provided. By the correlation of a single destructive measurement in order to determine the roughness and the conductivity measurement of a transition region, the roughness is determined for other s...

Zusammenfassung:	A method for determining the roughness of an internal surface of a metal substrate or a metal layer is provided. By the correlation of a single destructive measurement in order to determine the roughness and the conductivity measurement of a transition region, the roughness is determined for other samples without destructive measurement.
