| 2 | N_2-O_2-SO_2气氛中沉积盐引起Fe_3Al和FeAl的热腐蚀显示文摘研究表面分別有混合盐Na_2SO_4-NaCl,Na_2SO_4-V_2O_5和纯Na_2SO_4沉积并在模拟燃气气氛中Fe_3Al和FeAl于600℃的热腐蚀,在所有试验条件下两种合金均发生热腐蚀。随试验时间的延长、纯Na_2SO_4和Na_2SO_4-NaCI引起的腐蚀明显减缓,而Na_2SO_4-V_2O_5的腐蚀则加剧并长时持续。FeAl一般较之Fe_3AI耐蚀,只有在Na_2SO_4-NaCl情况下两者腐蚀性能相近。所有合金的腐蚀产物层总是由一高铁的外层和含铝与铁和少量硫的内层组成,后者的成分随所涂盐的组成而变化。在一定程度上腐蚀机制涉及氧化-硫化与氧化物的熔融等。 | 牛焱 吴维(山文) F.Gesmundo F.Viani | 1993 | 腐蚀科学与防护技术1993，5，1： | 1 |
| 3 | Sulphidation of Fe-Nb,Co-Nb and Ni-Nb Alloys in H_2-H_2S at 700℃显示文摘The corrosion of alloys based on Fe,Co and Ni containing 15 and 30 wt-% Nb was studied at 700℃in H2-H2S mixtures providing 10-8 atm S2.The Fe and Co-based alloys formed duplex scales withan outer layer of pure base-metal sulphide and an inner layer containing both metals.The Nb addi-tions were not able to produce exclusive Nb sulphidation but yielded a significant decrease of thecorrosion rates for both types of alloys with respect to the pure metals even though they were stillmuch higher than that of pure Nb.The Ni-base alloys corroded rapidly forming a single complexscale layer,mainly due to the appearance of a liquid Ni-S solution. | F.Gesmundo F.Viani Y.NIU | 1993 | Journal of Materials Science & Technology1993，9，3： | 0 |
