采用燃烧器(台架)试验,随后进行腐蚀试样的金相检查来评价旨在防止在硫化环境中的金属侵蚀的腐蚀缓蚀剂。在一组标准硫化条件下所研究的9种不同添加物处理中,Cr-Si(Cr/Na=2.25,Si/Na=1)和Cr(Cr/Na=4.5和2.5)添加物是最有效的,而且添加Cr-Si比单独加Cr略胜一筹,某些其他添加材料,如Mg虽可阻止侵蚀,但不象Cr-Si和Cr那样防止腐蚀阶段的扩展。像Ti和Ce这样的材料,它们作为合金化添加元素对抗硫化热腐蚀是有益的,但作为燃料中添加剂并非是成功的缓蚀添加剂。
Burning (gantry) testing was followed by metallographic examination of the corroded samples to evaluate corrosion inhibitors designed to prevent metal attack in the vulcanized environment. Cr-Si (Cr / Na = 2.25, Si / Na = 1) and Cr (Cr / Na = 4.5 and 2.5) additives were the most effective additives in the nine different additive treatments studied under one set of standard vulcanization conditions , And adding Cr-Si is slightly better than adding Cr alone. Some other additives, such as Mg, prevent erosion but do not prevent the corrosion phase from expanding as did Cr-Si and Cr. Materials such as Ti and Ce are useful as alloying additions to sulfidation hot corrosion, but are not successful corrosion inhibitors as fuel additives.
