Currently, the service temperature of the MCrAlX coating (M= Ni, Co, or NiCo; X= minor
elements such as Y, Ce, Si, Ta) either as an overlay or as a bondcoat in some critical …

Air plasma sprayed thermal barrier coatings (TBCs) are widely used in gas turbines to
provide thermal insulation for the metallic engine components. During service, the multi …

This paper examines and compares the microstructure and oxidation behaviour of
CoNiCrAlY coatings manufactured by the APS, HVOF and CGDS deposition techniques …

MCrAlY coatings are widely preferred in materials used at high temperature applications
exposed to oxidation and hot corrosion. The coating process used in the production of …

TBCs provide protection of superalloy substrates against harsh environments in gas turbine
engines. Typical TBCs consist of two main coating layers called bond and top coat …

Abstract Nano-CeO 2 reinforced NiCoCrAlY nanocomposite coatings were applied by high
velocity oxygen fuel spraying (HVOF) method. To prepare nano-CeO 2 reinforced …

Conventional and nanocrystalline MCrAlY coatings were applied by the high-velocity oxy-
fuel (HVOF) deposition process. The ball-milling method was used to prepare the …

This study is focused on the variation of the microstructures of different CoNiCrAlY bond
coats sprayed by the high-velocity oxy-fuel (HVOF) process for thermal barrier coating (TBC) …

NiCoCrAlY and CoNiCrAlY bond coats used for thermal barrier coatings, as well as 8 wt% Y
2 O 3-stabilized ZrO 2 (8YSZ) ceramic top coat, were air plasma sprayed on Inconel 718 …

CoNiCrAlY coatings were deposited on IN-738 LC substrates using HVOF technique. The
microstructure of these coatings is composed of a single γ phase. A two-step high vacuum …
