Similar to grinding, the materialographic polishing process is based on material removal by cutting. However, it is polished with much smaller grain sizes, which means that the removal rate is much lower than with grinding.
The process is divided into pre-polishing and final polishing. In one or more steps, the polishing is gradually refined until any remaining deformation of the sample is noticeably reduced and scratches are no longer visible, even microscopically. Only loose, abrasive grit is used here, which is applied to a polishing cloth. At the end of the polishing process, the material sample shows a polished surface suitable for chemical etching and subsequent microstructure assessment.
In order to achieve such exact polished surfaces, SCAN-DIA offers a comprehensive range of products and only uses high-quality components for the production of polishing agents.
PLAN-O-GRIP
Polishing cloth for pre-polishing
The polishing cloth has either a self-adhesive or a magnetically adhesive back. It is used for pre-polishing ferrous metals, non-ferrous metals or ceramics. The removal rate is high. With this cloth, a very good flatness of the surface can be achieved reproducibly.

DIAMONDPASTE
Polishing agent
This DIAMANTPASTE has been specially developed for materialographic use. In a practical nylon syringe, it is a very economical and highly concentrated polishing agent for manual and semi-automatic polishing. The paste is soluble in alcohol, oil and water. SCAN-DIA offers the DIAMANTPASTE with extremely narrow grain size tolerances.
