Field metallographic replication is a (semi) non-destructive test required in some applications where it is not possible to remove a component from service or the size of the components prohibits analysis in the laboratory.

Assorted replicating media techniques allow our experts to create a portable copy of the microstructure of interest while in the field. Replication involves removal of the material’s surface by lightly grinding, followed by polishing using fine grits.

Once the surface is properly polished and prepared, it is then etched with various acids to reveal the materials microstructure. The replicating media is then applied and allowed to cure. Once the replicating media is cured, it will be removed from the sample, returned to our laboratory, and analyzed using a variety of microscopes.

Replication can also be performed to replicate surfaces for surface finish or other testing, replicating shapes, corrosion pitting, cracking or any other surface that require imaging or measurements.
