Microstructural investigation of the kappa-Al2O3-to alpha-Al2O3 transformation in multilayer coatings of chemically vapor deposited kappa-Al2O3@abs The kappa-to alpha transformation in different multilayer coatings of kappa-Al2O3 has been investigated. All the multilayers had the same total thickness (8 microns) but a different number of layers (8, 15 and 32). The transformation was studied with respect to (1) rate of transformation, (2) transformation growth, (3) morphology and (4) the adhesion - NASA/ADS
