  • AbstractIntroductionExperimental ProceduresResults and DiscussionSurface CharacterizationScanning Electron MicroscopyCross-Section CharacterizationAcknowledgmentsThe failure of the protective oxide scales of AISI 304 and AISI 316 stainless steels has been studied and compared at 1,000°C in synthetic air. First, the isothermal thermogravimetric curves of both stainless steels were plotted to determine the time needed to reach the breakdown point. The different resistance of each stainless steel was interpreted on the basis of the nature of the crystalline phases formed, the morphology, and the surface structure as well as the cross-section structure of the oxidation products. Ablation Stability of In Situ Al2O3 Layer in Aluminized May 27, 2021 · The degradation and stability behavior of AISI 4130 steels have been examined under high-temperature dynamic plasma flame environments. A Fe 2 Al 5 layer was formed as a result of aluminizing on the steel. An Al 2 O 3 layer was produced on top of the Fe 2 Al 5 layer, when the coated steel was oxidized at 500 °C (pre-oxidation treatment). The uncoated steels and the Fe 2 Al 5 coated

    CORROSION AND OXIDATION BEHAVIOR OF POLYMER

    No oxidation of the top coat was detected after the static corrosion test. The high temperature oxidation behaviour in a flow-through oxygen atmosphere was investigated at the temperatures of 900°C, 1000°C and 1100°C. X-ray diffraction confirmed extensive corrosion of the uncoated AISI 441 stainless steel accompanied by formation of a Cr 2O Cyclic Oxidation Behavior of 310S Austenitic Stainless Systematic study were undertaken to understand the high temperature oxidation behavior of AISI 310S Stainless steel. The tests were conducted at two temperatures of 9300C and 960C up to 135 hours. A comparative study of weight gains for these two different temperatures was observed. The parabolic curve was found.

    Effect of Humidity on High Temperature Oxidation of AISI

    In order to investigate the high temperature oxidation behavior of AISI 430 stainless steel in atmosphere with humidity, the thermogravimetric analysis (TGA) has been conducted for different duration under air with variable absolute humidity (from 0% to 5%) at 800 °C and 900 °C. XRD has been used to determine residual stresses in each layer and in substrate. High Temperature Degradation of Thermal Oxides on AISI AISI 304 austenitic stainless steel specimens are oxidised in laboratory air at 750 °C for 48 h. They are further subjected to the reduction test in carbon at 1350 °C for 30 and 60 min. The results show that the mass gain of the oxidised AISI 304 slighter increases to be 0.08 mg cm2 after the reduction for 30 min and is unchanged at the longer reduction period up to 60 min.

Lanthanum Effect on the Isothermal High Temperature Many studies have shown that a phosphoric-acid treatment improves the high temperature oxidation resistance in air of some alloys. Interestingly, though, the phosphoric-acid treatment generates a structural modification of the steel surface which is catastrophic for the high-temperature oxidation behavior at 1,000 °C. The aim of our work was to test the effect of a reactive element solgel
