Plasma-sprayed yttria-stabilized zirconia coatings on type 316L stainless steel for pyrochemical reprocessing plant

“…In zirconia, coating impurities like SiO 2 , TiO 2 , Al 2 O 3 and Fe 2 O 3 are present in small quantities, and the temperatures of such chlorides at the critical vapour pressure (10 À4 bar) where they would evaporate are À235 K (TiCl 4 ), 349 K (AlCl 3 ), and 440 K (FeCl 3 ) [13]. Hence significant evaporation of these metal chlorides may occur when the components operate at high temperatures.…”

“…Critical vapour pressure values of the metal chlorides are often used to assess the resistance of different materials to chlorides [13]. In zirconia, coating impurities like SiO 2 , TiO 2 , Al 2 O 3 and Fe 2 O 3 are present in small quantities, and the temperatures of such chlorides at the critical vapour pressure (10 À4 bar) where they would evaporate are À235 K (TiCl 4 ), 349 K (AlCl 3 ), and 440 K (FeCl 3 ) [13].…”

Microstructure and Corrosion Resistance of Aluminium and Copper Composite Coatings Deposited by LPCS Method

“…In the case of Cu+Al 2 O 3 coatings, the upper part was covered with a single layer of black patina (Fig. 6e) [38]. Furthermore, while in the SO 2 atmosphere, the patina may additionally contain other hydroxy-sulphates [39].…”

“…5b), as aluminium exhibits poor resistance to acids and bases. The film is particularly vulnerable to destruction in the presence of chlorides [37,38]. As a result of the Cl-environment, white spots were observed, which increased considerably after the last cycle (Fig.…”

Au/CeO2 metallic monolith catalysts: influence of the metallic substrate

“…The most popular pre-treatments consist of generating a stable, resistant, rough, well-adhered and homogenous oxide scale on the surface, directly grew from the metallic bulk. The composition of such oxide scale, as well as the pre-treatment method used, depends on the metal substrate [4,5]. Thus, thermal treatments have been demonstrated as very efficient for austenitic [3,6,7] and ferritic stainless steels [7][8][9] while anodisation is the elected method for aluminium surfaces [10,11].…”
