Alloy 825(合金825)研究综述
Alloy 825 合金825 - In this study, the corrosion performance of the three candidate alloys (SS347, Alloy 800AT and Alloy 825) was investigated in the hot flue gas mixtures (60% H2O + 33% CO2 + 2-7% O2) at 600 °C and 15 MPa to simulate typical pressurized oxy-fuel natural gas combustion environments. [1] Grain boundary engineering (GBE) by appropriate deformation and heat treatment processes was applied to nickel-based alloy 825 due to its excellent corrosion resistance. [2] Alloy 825 is a nickel-based alloy that is commonly used in applications where both high strength and corrosion resistance are required, such as tanks in the chemical, food and petrochemical industries and oil and gas pipelines. [3] Wrought nickel-based Alloy 825 is widely used in the oil and gas industries, attributed to its high strength at temperatures up to 540 °C. [4] The effect of high temperature on corrosion behavior and passive film composition of Ni-based alloy 825 in H2S-containing environment was investigated by Confocal Laser Microscope (CLM), Scanning Electron Microscope (SEM), Energy Dispersive Spectrometer (EDS), and X-ray Photoelectron Spectroscopy (XPS). [5] The present study aims to compare the hot corrosion resistance of bare and Ni-20%Cr coated Ni-Fe based superalloy 825 in Na2SO4-60%V2O5 molten salt environment at 900°C. [6]在这项研究中，研究了三种候选合金（SS347、合金 800AT 和合金 825）在热烟气混合物（60% H2O + 33% CO2 + 2-7% O2）中在 600 ℃和 15 MPa 模拟典型的加压氧燃料天然气燃烧环境。 [1] 由于镍基合金825具有优异的耐腐蚀性，通过适当的变形和热处理工艺进行晶界工程（GBE）。 [2] 合金 825 是一种镍基合金，通常用于需要高强度和耐腐蚀性的应用中，例如化学、食品和石化行业的储罐以及石油和天然气管道。 [3] 锻造镍基合金 825 广泛用于石油和天然气行业，这归功于其在高达 540 °C 的温度下的高强度。 [4] 采用激光共聚焦显微镜（CLM）、扫描电子显微镜（SEM）、能谱仪（EDS）和X-射线等方法研究了高温对Ni基合金825在H2S环境中腐蚀行为和钝化膜成分的影响。射线光电子能谱（XPS）。 [5] 本研究旨在比较裸露和 Ni-20%Cr 涂层 Ni-Fe 基高温合金 825 在 Na2SO4-60%V2O5 熔盐环境中 900°C 的抗热腐蚀性能。 [6]
