摘　　要：在模拟炼厂环境的环烷酸腐蚀(NAC)动态试验中,应用失重法研究了温度、酸值和介质流速对铬钼钢环烷酸腐蚀速率的影响;采用扫描电子显微镜和光学显微镜观察的方法,从微观上分析了铬钼钢的环烷酸腐蚀行为。In a dynamic test of naphthenic acid corrosion simulating the environment of oil refineries,the influences of temperature,acid value,flow velocity of mediums on the corrosion rate of Co-Mo steel were studied using weight loss method,the corrosion behavior of the Cr-Mo steel in nathenic acid was microscopically analyzed through observation using SEM and OM.
