...Abdul Rehman; Mohammad Hassan Shirani Bidabadi; Liang Yang; Zheng Yu; Chen Hao; Chi Zhang; Zhigang Yang Purpose This study aims to optimise the effect of pre-oxidation on hot corrosion behaviour of Tribaloy T-900 at 900 °C in mixed Na₂SO₄ and K₂SO₄...

.../methodology/approach The oxide passive layer on aluminium was examined using DEIS under non‐stationary conditions of linearly raised and lowered temperatures. In total, five heating‐cooling cycles were performed. Findings A significant change of impedance was observed only during the first cycle, which...

...M. Jariyaboon; P. Møller; R.E. Dunin‐Borkowski; R. Ambat Purpose The purpose of this investigation is to understand the structure of trapped intermetallics particles and localized composition changes in the anodized anodic oxide film on AA1050 aluminium substrates. Design/methodology/approach...

...M. Aliofkhazraei; A. Sabour Rouhaghdam; M. Laleh; A. Shanaghi Purpose Uniform nanostructured TiO₂ thin film has been applied as an over coat on micro‐arc oxidized substrate, using the sol‐gel method. The anticorrosion performance of the coating have been evaluated using electrochemical...

...H. Singh; D. Puri; S. Prakash; M. Srinivas Purpose To characterise the high temperature oxide scales for some plasma sprayed NiCrAlY coated Ni‐ and Fe‐based superalloys. Design/methodology/approach Ni‐22Cr‐10Al‐1Y metallic coatings were deposited on two Ni‐based superalloys; Superni 601...

...Nivin M. Ahmed; Adel Attia; Mohamed M. Selim Purpose Aims to study inhibitive properties of new compounds that are based on the Wurtzite structure of zinc oxide with an admixture of cobalt using zinc oxide as a reference. Design/methodology/approach The conditions for the preparation...

...M.A. Quraishi; Hariom K. Sharma Stainless steel 316 was coated with CeO₂ and Y₂O₃ modified aluminide and titanium aluminide coatings. The coatings were prepared by the pack cementation method and the high temperature oxidation behaviour of the coatings...
