Isothermal oxidation behavior of NiCoCrAlY/ZrO₂ composite coating on γ-TiAl alloy

Study on production of modified MCrAlY powder with nano oxide dispersoids as HVOF thermal spray feedstock using mechanical milling

“…In fact, the composition and growth rate of the TGO layer varies according to the coating properties such as the chemical composition, microstructure, and oxides content [8]. These coatings have been manufactured by methods of physical vapor deposition (PVD) [9], magnetron sputtering [10], arc ion plating (AIP) [11], thermal spraying [12][13][14][15] and laser powder deposition (LPD) [16]. The MCrAlY coatings deposited using the HVOF process often have better properties in comparison to the other thermal spraying methods and in some cases provided higher oxidation resistance [17,18].…”
