Question

explain the need of washing an drying of metallographic samples before proceeding from one grinding or polishing operation to the next

Answer 1

Metallography is finding out about the structure of metals. Nowadays however, the description “Materialography“ is preferred due to the increasing number of composite matter such as the development of additional materials (ceramic/metallic systems, metallic/plastic systems, etc.). Deployment areas of metallography i.e. materialography lie mainly in quality control and damage analysis as well as in R & D.
