The effect of NiCr intermediate layer on corrosion behavior of Cr2O3 ceramic coated materials

Mechanical and metallurgical properties of plasma sprayed and laser remelted Ni–20Cr and Stellite-6 coatings

“…The phases identified by XRD for as-sprayed coatings are similar to those analysed by Li et al [29] and some more phases reported by them may be due to the different type of plasma spray process, i.e. shrouded for this study and air plasma spray used by them.…”

Influence of aqueous aging on surface properties of plasma sprayed oxide coatings

“…There is only one published study available concerning surface acidity of plasma sprayed oxides [7]. Since the plasma sprayed coating is always more or less porous, most of the corrosion studies performed for these coatings have concentrated on characterizing dissolution behaviour of under laying metal layer [8][9][10][11][12]. The only corrosion study [13], which considers the dissolution Table 1 Studied coating materials and their composition.…”

Tribological properties of atmospheric plasma sprayed Cr2O3 coatings: Effect of NiAl bond coating

“…Usually, a combination of ceramic and metallic materials is used in the form of coating and bond coating on metallic substrates, enhancing the existent surface properties. 2,3 In the present work, the microstructural, tribological and mechanical properties of three coatings (Cr 2 O 3 , NiAl and Cr 2 O 3 -bond coating NiAl), obtained by atmospheric plasma spraying on medium carbon steel, have thoroughly been investigated. The effect of the bond coating (NiAl) on the properties of ceramic coating has also been investigated.…”
