Hydrogen peroxide (H2O2) is a kind of ideal green propellant. It is crucial to study the wear behavior and failure modes of the metal materials under the strong oxidizing environment of H2O2. This study aims to investigate the wear of rubbing pairs of 2Cr13 stainless steel against 1045 metal in H2O2 solutions, which has a great effect on wear, the decomposition and damage mechanism of materials. The comparison analysis of the friction coefficients, wear mass loss, worn surface topographies and current densities was conducted under different concentrations of H2O2 solutions. There were significant differences in the tribological and electrochemistry properties of the rubbing pairs in different H2O2 solutions.

深入研究碳捕集、利用与封存(CCUS)技术中的金属腐蚀问题产生的机理和影响,对有效应对和解决捕集、运输、利用与封存系统中存在的材料腐蚀失效问题至关重要,为此,本文对CCUS技术存在的金属腐蚀问题研究进展及挑战进行了综述。本文基于CCUS技术各系统腐蚀环境新颖、腐蚀行为特殊、认知程度有限、防护手段相对匮乏等情况,结合CCUS各系统中的腐蚀环境特点,分析了可能存在的金属腐蚀类型及其主要影响因素,并对其带来的挑战进行了梳理,得出了以下主要结论:对于有机胺捕集系统,吸收剂降解机理及降解产物对腐蚀过程的影响较为复杂,部分降解产物对金属腐蚀有抑制作用;密相CO2输送管道的内腐蚀问题不容忽视,控制水分含量是控制该腐蚀问题的关键;CO2驱油利用与封存系统井筒管材在超高CO2分压、碳源杂质、高矿化度地层水、微生物和应力等多因素的长周期耦合作用下,出现腐蚀失效导致CO2泄露的风险很高。最后,本文对未来需迫切开展的研究方向进行了展望,包括不同碳源杂质对各子系统的腐蚀影响研究、长期封存条件下井筒区域材料降解规律研究以及CCUS系统腐蚀防护技术研究等。

Recently, more and more attention is paid on applications of molten chlorides in concentrated solar power (CSP) plants as high-temperature thermal energy storage (TES) and heat transfer fluid (HTF) materials due to their high thermal stability limits and low prices, compared to the commercial TES/HTF materials in CSP-nitrate salt mixtures. A higher TES/HTF operating temperature leads to higher efficiency of thermal to electrical energy conversion of the power block in CSP, however causes additional challenges, particularly increased corrosiveness of metallic alloys used as containers and structural materials. Thus, it is essential to study corrosion behaviors and mechanisms of metallic alloys in molten chlorides at operating temperatures (500–800 °C) for realizing the commercial application of molten chlorides in CSP. The results of studies on hot corrosion of metallic alloys in molten chlorides are reviewed to understand their corrosion behaviors and mechanisms under various conditions (e.g., temperature, atmosphere). Emphasis has also been given on salt purification to reduce corrosive impurities in molten chlorides and development of electrochemical techniques to in-situ monitor corrosive impurities in molten chlorides, in order to efficiently control corrosion rates of metallic alloys in molten chlorides to meet the requirements of industrial applications.

腐蚀管理关乎安全生产,关乎国民经济,关乎生态文明,关乎资源节约和国家建设。虽然少数行业在腐蚀管理方面已经进行了一些卓有成效的探索和实践,但是总体上腐蚀管理在我国发展十分不平衡,存在着腐蚀管理意识薄弱、专业人才短缺和管理系统不健全等问题。因此,有必要进一步明确腐蚀管理的内涵,明确我国腐蚀管理体系化发展的基本要求,推动腐蚀管理体系化持续健康发展。本文基于中国工程院重点咨询项目“我国腐蚀管理状况与对策战略研究”主要研究成果,阐述了腐蚀管理的内涵及体系化发展的重要意义,分析了我国腐蚀管理的现状及问题,总结提出了腐蚀管理体系基本框架及管理要点,提出了将腐蚀管理纳入国家安全战略,成立腐蚀管理战略研究常设机构;加强腐蚀学科建设,强化人才战略;建立健全腐蚀防护相关法规标准,强化标准意识;加强腐蚀数据库建设,畅通沟通渠道;搭建腐蚀管理信息及大数据交流平台,打造共享管理新模式等对策建议。
