TURBOCHARGER HEAT SHIELD THERMAL BARRIER COATINGS
Provided herein are thermal barrier coatings (TBC) and turbocharger heat shields comprising the same. The turbocharger heat shield can be metallic and include a front face having an aperture capable of accepting a turbocharger shaft. The TBC can include a bond coat applied to the turbocharger heat shield, an interfacial layer contacting the bond coat, and a ceramic top coat contacting the interfacial layer. The bond coat of the TBC can comprise nickel, at least about 4% aluminum, up to about 36% chromium. One or more of the one or more of the interfacial layer and the ceramic top coat can comprise aluminum oxide, titanium oxide, spinel, yttria-stabilized zirconia, gadolinium zirconate, and combinations thereof. One or more of the interfacial layer and the ceramic top coat can be free from yttria-stabilized zirconia and gadolinium zirconate. The TBC can have a total thickness of at least about 100 μm.
