Education Courses - The Metallographic Preparation of Gas Turbine Coatings
May 12, 2007 – 8:00 a.m. – 5:00 p.m.
Crowne Plaza Park View Wuzhou Beijing
Beijing, China
| Instructor: | Douglas G. Puerta Director of Metallurgical Engineering IMR Test Labs Lansing, New York |
Course Overview:
The accurate evaluation of a gas turbine coating is contingent upon proper metallographic preparation. Poor preparation can lead to false conclusions about coating integrity or spray booth parameters. As a result, parts may unnecessarily be reworked or scrapped. Even worse, misevaluation may lead to a bad part “escaping” into service.
This course covers a wide range of topics relating to the metallographic preparation and evaluation of gas turbine coatings. Emphasis is placed on equipment and consumables selection, and how these choices influence the observed structure of a given coating.
In addition to an overview of metallographic preparation, we will also discuss common issues encountered with various coating families (e.g. hardcoats, ceramic (TBCs), etc.). Methods will be covered which can help to ensure that the true coating microstructure has been revealed.
Learning Objectives:
Understand the basic elements of metallographic preparation (sectioning, mounting, grinding, and polishing).
Learn the relationship between consumables, preparation recipes, and coating structure.
Determine if features observed within a given coating are inherent or have been induced during metallographic preparation.
Who Should Enroll:
This course should appeal to anyone involved in either the processing or evaluation of thermal spray coatings. Students will leave this course with a solid understanding of metallography and the role of metallography in producing a true coating structure.
