The thermal barrier coating is usually a multi-layer system consisting of a ceramic topcoat, a metallic bond coat and a superalloy substrate.
Thermal barrier coatings consisted of a CoNiCrAlY bond coat and a ceramic Zr[O.sub.2]-[Y.sub.2][O.sub.3] (yttria stabilized zirconia (YSZ)) top coat.
In a typical metal spray application 0.004"-0.008" of Ni/AI bond coat would be sprayed at around 0.002" per pass using the arcspray system.
The TBC systems usually consist of an MCrAlY bond coat (M = Ni and/or Co) as an oxidation-resistant layer, yttria-stabilized zirconia (YSZ) as a thermally insulating ceramic top coat, and a substrate (Ni-based superalloy) [1-5].
(48) Thus, it is highly desirable to engineer the substrate/HA coating interface in such a way that by application of a suitable thin biocompatible bond coat layer the advantages addressed above can be realized.
For such severe applications, we recommend a dual layer coating of 50Ni-50Cr alloy as a bond coat and titania (Ti[O.sub.2]) as a top coat by thermal spraying.
The topics include the full-scale numerical simulation of plasma-sprayed functionally gradient materials, the depletion model of aluminum in bond coat for plasma-sprayed thermal barrier coatings, developing spherical iron-based composite powder with carried alumina abrasive grains by plasma spray, processes and properties of ceramic coatings by elecrophoretic deposition, and the effect of silicon sol on anodic oxidation film of titanium alloys.
The shells consisted of a CP titanium substrate, with a titanium bond coat of arc deposited (AD) titanium beneath a plasma sprayed coating of manufactured HA.
The other layers include a strain tolerant interlayer, a mullite/rare-earth silicate environmental barrier layer, and an advanced ceramic oxide/mullite bond coat layer.
