Replication metallography is the use of thin plastic films to non-destructively duplicate the microstructure of a component. The film is then examined at high magnifications.
The typography of a surface is copied by casting or impressing material onto the surface. It is the commonly used technique to duplicate surfaces that are inaccessible in metrology to other forms of non-destructive testing.
Replication metallography is a cost-effective testing method that can be done on-site. Large or irregularly-shaped specimens may be replicated with relative ease.
