Round-Robin Test to Prepare a Sample of a Multifunctional Layer Sprayed onto a CFC Substrate

The Aachen working team hereby intends to make an active contribution to preparation-related publications and publish various suggestions for the preparation of its round-robin test which was made this year. The metallography working team in Aachen (AMA) is composed of a regional network of people engaged in metallography. The focus here is on a mutual exchange of experience in preparing complex material composites, inter alia. Round-robin tests are arranged with a view to better knowing the details of skills and experience of individual team members regarding their preparative techniques and possibilities of work based on their equipment. This year's round-robin test comprised the edge sharp preparation of a mullite functional layer sprayed onto a CFC substrate.
