Abstract Scope |
In this work, a new thermal barrier coating (TBC) deposited on additively manufactured (AM) nickel base superalloy substrate was developed. Yttria stabilized zirconia (YSZ), NiCrAlY and nickel base superalloy were used as the topcoat, bond coat, and substrate respectively. Selective laser melting (SLM) was used to fabricate buttons of 718 alloy for the TBC system with AM substrates. Microstructure and phase analyses were carried out to understand the effect of the fabrication route on the microstructure of the substrate. Mechanical property and thermal durability tests were also conducted. |
