摘要

为研究耐热钢高温腐蚀行为，选取630 ℃超超临界发电机组水冷壁使用的铁素体耐热钢T91为研究对象，开展不同负荷运行工况下耐热钢烟气腐蚀行为研究。采用分析天平测量耐热钢腐蚀前后质量变化，利用扫描电子显微镜、X射线衍射仪等设备表征腐蚀产物的形貌、成分及其分布。实验结果表明：500℃下耐热钢T91的腐蚀动力学曲线符合抛物线型规律，550℃和600℃下腐蚀动力学曲线在反应初期遵循抛物线型规律，分别在100h和75h转变为直线型规律，并且600℃下直线斜率增大，说明温度能够加速耐热钢腐蚀规律转变。耐热钢表面均呈现红褐色，表面形貌由丝状向尖晶石状和球状腐蚀产物转变。耐热钢T91表面腐蚀产物呈现三层腐蚀结构，由气体侧到基体侧腐蚀层分别为：Fe-O腐蚀层（主要为Fe

、Fe

）、FeS腐蚀层、Fe-Cr-O腐蚀层（FeCr

）。随着温度升高，腐蚀层厚度增加，温度身高100℃氧化膜厚度增厚42.9%。腐蚀层的生长机制由以阳离子向外扩散为主导，逐渐转变为以阴离子向内扩散为主导。这一转变导致氧化膜/基体界面处形成孔隙及硫化物等缺陷，加剧了电站锅炉水冷壁失效风险。

Abstract

To study the high-temperature corrosion behavior of heat-resistant steel

the ferritic heat-resistant steel T91

used in the water wall of a 630°C ultra-supercritical power generation unit

was selected as the research object to investigate the flue gas corrosion behavior of the heat-resistant steel under different load operating conditions. The mass changes of the heat-resistant steel before and after corrosion are measured using an analytical balance

and the morphology

composition

and distribution of corrosion products are characterized using scanning electron microscopy and X-ray diffraction analysis. The experimental results show that the corrosion kinetics curve of T91 heat-resistant steel at 500°C follows a parabolic rule

while at 550°C and 600°C

the corrosion kinetics curve initially obeys a parabolic rule and then transitions to a linear rule at 100 hours and 75 hours

respectively. Furthermore

at 600°C

the slope of the linear curve increases

indicating that temperature can accelerate the transition of corrosion patterns in heat-resistant steel. The surface of the heat-resistant steel all shows a reddish-brown color

and the surface morphology changes from filamentous to spinel-like and spherical corrosion products. The surface corrosion products of T

91 heat-resistant steel exhibit a three-layer corrosion structure

with the corrosion layers from the gas side to the base side being: Fe-O corrosion layer (mainly Fe

)

FeS corrosion layer

and Fe-Cr-O corrosion layer (FeCr

). As the temperature increases

the thickness of the corrosion layer increases

with a 42.9% increase in oxide film thickness per 100°C rise. The growth mechanism of the corrosion layer shifts from being dominated by cation diffusion outward to being dominated by anion diffusion inward. This transition leads to the formation of pores and defects such as sulfides at the oxide film/base interface

exacerbating the risk of failure of the water-cooled wall in power plant boilers.
