Abstract

The goal of this year's Pratt and Whitney/WPI Learning Factory project was to create a rules based software system that would specify the process parameters to fabricate a contoured electron beam physical vapor-deposited thermal barrier coating on a PW4000 second stage turbine blade in Pratt and Whitney's coater one. Shadow and cylinder experiments were carried out. Microstructure analysis was also done on the tabs in an attempt to find a correlation between X-ray diffraction readouts and crystal growth angles During this project, no correlation could be found, but a rules based design system for the coating thickness on a cylinder was completed.
