...Jing Wu; Xuguang An; Hui Wang Purpose This study aims to report the oxidation behaviors of the T91 ferritic/martensitic steel (T91 steel) and 304 austenitic stainless steel (304 steel) in supercritical water (SCW) at 600°C. Design/methodology/approach The microstructure, elemental distribution...

...Chunmei Ma; Songting Yang; Yuheng Zhang; Kaikun Wang; Huadong Fu Purpose Due to the special service environment of superalloys, this paper aims to obtain effects of temperature and Ti addition on high temperature oxidation behavior of Co-Al-W-B alloys. Design/methodology/approach Isothermal...

...Q. Wan; Y.M. Chen; H.D. Liu; B. Yang Purpose Ti-Si-N coating with nanocomposite structure is a promising protective coating for cutting tools which will be subject to high temperature oxidation during service. This study aims to investigate the thermal stability of Ti-Si-N coatings and lays...

... – The samples were prepared by casting, and then were oxidized at 1,000°C for 30, 70 and 100 hours, respectively. To determine corrosion resistant of the samples, they were exposed to molten cryolite at 930°C for 70 hours. Then the surface layers were studied. Findings – Results showed that by extension...

...Yan Jun Xi; Yong Jun Liu; Zhi Xin Wang; Jin Bin Liu Purpose The purpose of this paper is to investigate the oxidation behavior of Ti‐48Al‐8Cr‐2Ag (at.%) at 900°C and 1000°C for various different times. Design/methodology/approach Laboratory tests were performed to determine growth process...

... of Na₂O₂ additions at temperatures of 475, 500, 525 and 550°C. The techniques of measurements were open circuit potential, galvanostatic anodic polarisation and cyclic voltametry. The addition of Na₂O₂ increased the concentration of oxide ions in the carbonate melt...

...H.A. Abdel‐Hakim Ali; A.A. Attia; A.N. Al‐Masri; A.M. Baraka This article presents the galvanostatic anodic oxidation of two types of stainless steel alloys, ferritic (15.03% Cr) and austenitic (20.45% Cr, 8.37% Ni), in molten NaNO₃‐KNO₃ eutectic mixture at different...

...A. van Bennekom; J.H. Potgieter The failure of a conditioning tower at a cement plant was investigated. It was found that the structure failed due to a combination of high temperature oxidation and sulphidation. This was aggravated by the presence of sodium and potassium salts in the exit gases...
