摘要：大气中的臭氧氧化性强,对金属材料的破坏作用非常大。以碳钢为基体,测试其在臭氧存在条件下的腐蚀行为,并进行了自然空气条件下的对比试验;采用扫描电镜、能谱分析和激光拉曼等技术分析了不同条件下碳钢的腐蚀形貌及腐蚀产物,初步探讨了碳钢在臭氧气氛中的腐蚀机理。结果表明,与在自然空气中相比,碳钢在臭氧中的腐蚀更为严重,并且随时间延长腐蚀加重。腐蚀初期产物的主要成分为γ-FeOOH和γ-Fe2O3,随着腐蚀时间的延长,γ-FeOOH会逐步脱水形成γ-Fe2O3和α-Fe2O3。
Because of the strong oxidizing property,ozone in the atmosphere has great disruptive effects on metal materials.The initial corrosion behaviors of carbon steel in the atmosphere with ozone were studied by setting contrast test in natural air.The corrosion appearance and products of carbon steel under different corrosion conditions were investigated by SEM/EDS and Raman,and the corrosion mechanism was studied preliminarily.The results showed that,compared with the corrosion of carbon steel in natural air,ozone can accelerate the corrosion of carbon steel,and with the extension of time,ozone can aggravate the degree of corrosion.The main corrosion products generated on the surface of carbon steel wereγ-FeOOH andγ-Fe2O3,thenγ-FeOOH dehydrated and bormedγ-Fe2O3andα-Fe2O3.
