Abstract

Characterization of ultra-finely finished surfaces (e.g. mirrored surfaces or polished specimens) is nowadays challenging due to possible part damage if a contact instrument is used or due to scattered light if the measurements are performed with optical instruments. In order to prevent these problems, surface replication is considered as a method to make feasible the characterization of the polished specimens. This paper focuses on the investigation of surface characterization based on replication methods using soft and hard polymer casting. The study deals with the evaluation of the replication degree between the master and the replica as well, the different replication materials involved, the different instruments used and the calculation of the measurement uncertainty for both sub-micro surface topography and micro geometrical measurements.
