In order to find a kind of low-cost and high-capability catalyst for methane combustion, a series of CeO_2-ZrO_2-Al_2O_3 solid solution, in which the content of Ce_0.67Zr_0.33O_2 and Al_2O_3 were different, were prepared by co-precipitation method.

近年来，非贵金属氧化物甲烷燃烧催化剂的研究虽然十分活跃，但对铁基氧化物催化剂研究不多，其主要原因是铁基氧化物催化剂对甲烷燃烧的催化活性较差。

When Ts is 850 ℃,grains are fined and the size of βphase and the distance betweenβphase pasticles are small.The corrosion barrier effect ofβ phase onαphase is enhanced and the iron content does not increase much at this temperature.So the corrosion resistance is improved.The corrosion resistance of AZ70 alloy falls off when Ts is 890 ℃,which attributes to the presence of microporosity,hot cracking and increase of iron content.

过热温度为810 ℃时，热速处理对合金耐腐蚀性能的改善作用并不大；过热温度为850 ℃时，热速处理显著细化了合金晶粒，β相的尺寸和间距变小，β相对α相腐蚀的阻碍作用增加，而且合金中的铁含量并没有提高，从而改善了合金在试验条件下的耐腐蚀性能；过热温度为890 ℃时，组织中存在热裂纹和显微疏松缺陷，合金含铁量显著增高，合金的耐腐蚀性能下降。
