Journal ArticleDOI
Jet engine coatings for resisting volcanic ash damage.
Julie M. Drexler,Andrew D. Gledhill,Kentaro Shinoda,Alexander L. Vasiliev,Kongara M. Reddy,Sanjay Sampath,Nitin P. Padture +6 more
TL;DR: Jet engine coatings are discussed in this paper and there is a growing need to build protective measures within modern jet engines against damage from a broad range of undesirable silicate deposits.
Journal ArticleDOI
Air-plasma-sprayed thermal barrier coatings that are resistant to high-temperature attack by glassy deposits
Julie M. Drexler,Kentaro Shinoda,Angel L. Ortiz,Dongsheng Li,Alexander L. Vasiliev,Andrew D. Gledhill,Sanjay Sampath,Nitin P. Padture +7 more
TL;DR: In this article, the use of the commercial manufacturing method of air-plasma-spray (APS) to fabricate CMAS-resistant yttria-stabilized zirconia (YSZ)-based TBCs containing Al and Ti in solid solution was demonstrated.
Journal ArticleDOI
High quality, transferrable graphene grown on single crystal Cu(111) thin films on basal-plane sapphire
TL;DR: In this paper, the authors showed that large-area graphene can be grown on epitaxial single-crystal Cu(111) thin films on reusable basalplane sapphire [α-Al2O3(0001)] substrates for transfer to another substrate.
Journal ArticleDOI
Plasma sprayed gadolinium zirconate thermal barrier coatings that are resistant to damage by molten Ca–Mg–Al–silicate glass
Julie M. Drexler,Chun-Hu Chen,Andrew D. Gledhill,Kentaro Shinoda,Sanjay Sampath,Nitin P. Padture +5 more
TL;DR: In this article, air plasma sprayed (APS) Gd 2 Zr 2 O 7 thermal barrier coatings (TBCs) are found to be highly effective in resisting high-temperature (1200°C) penetration of molten Ca-Mg-Al-silicate (CMAS) glass deposit for prolonged durations (up to 1 week).
Journal ArticleDOI
Mitigation of damage from molten fly ash to air-plasma-sprayed thermal barrier coatings
Andrew D. Gledhill,Kongara M. Reddy,Julie M. Drexler,Kentaro Shinoda,Sanjay Sampath,Nitin P. Padture +5 more
TL;DR: In this article, the authors used lignite fly ash to simulate these conditions and showed that conventional TBCs of composition 93% ZrO 2 ǫ + 7% Y 2 O 3 (7YSZ) fabricated using the air plasma spray (APS) process are completely destroyed by the molten fly ash.
