据《Turbomachinery International》2010年3～4月号报道,在上一期中,Solar Turbines(索拉透平公司)的专家们介绍了燃气轮机的腐蚀并探讨了腐蚀的一些类型。在这一期中他们更多地探讨腐蚀的机理。硫化是金属和含氧含硫介质之间形成硫化物和氧化物的反应。硫化侵袭使金属的性能迅速下降。燃气轮机中的氧化和热腐蚀问题典型地与燃烧室和涡轮部分内的高温有关。压气机涂层可以有效地保护压气机叶片免受水溶性腐蚀。氧化通常不是一个需要关注的主要问题。
According to Turbomachinery International, March to April 2010, in the previous issue, experts from Solar Turbines introduced gas turbine corrosion and explored some types of corrosion. In this issue they explore more about the mechanism of corrosion. Vulcanization is the reaction of forming sulfides and oxides between a metal and an oxygen-containing sulfur-containing medium. Vulcanization attacks quickly degrade metal properties. Oxidation and hot corrosion issues in gas turbines are typically associated with high temperatures within the combustor and turbine sections. Compressor coating can effectively protect the compressor blades from water-soluble corrosion. Oxidation is not usually a major concern.
