| 摘 要： | 采用间歇式超临界水氧化装置，对316L不锈钢网状试样和块状试样在超临界水氧化处理城市污泥环境中的腐蚀特性进行了研究。结果表明，试样的腐蚀程度随氧化系数的提高而加剧，碱性条件下网状试样表面有富含Mo和Ni的丝状无机盐生成。与网状试样不同，块状试样在高氧化系数和酸性条件下均表现出点蚀形貌，在酸性条件下腐蚀速率最高达0．17...

| Abstract: | The corrosion behavior of 316L stainless steel netlike and block samples was studied in city sewage sludge treated by supercritical water oxidation(SCWO).The results showed that the corrosion of 316L was enhanced as the oxidation coefficient increased.Filament mineral salts rich in Mo and Ni were found on the outer surface of the net like sample under alkaline condition.Different from the net like sample,on the block sample pitting corrosion morphology was observed under the acidity and high oxidation condi... |
