In the other hand, graphite carbon and SiC oxidizing produce CO、SiO〓 and in the same time CO separates graphite carbon partially, this effect will decrease decarburizing rate and corrosion rate for Al〓O〓-SiC-C brick. TiO〓 and SiO〓 protective layer forming and separating graphite carbon are the main factor of resistance smelting reduction molten slag-iron to corrode and the main feature of corrosion process.

Al〓O〓-C-SiC砖在侵蚀过程中，由于SiC氧化后产生CO，SiO，并析出碳和降低耐火材料气孔率及氧化形成的SiO〓成为保护膜，使熔体对耐火材料的侵蚀能力降低，这两种耐火材料的侵蚀速度都是随着使用时间延长，耐火材料侵蚀速度逐渐降低。

At the same time, the fouling mechanism of membranes given in this thesis can give a reasonable explanation on the change of membrane performance. Our results show that the magnetization of membranes can effectively improve the anti-fouling ability of the PAN- Fe_3O_4 membrane. The obtained result may give insight to the development of new membranes with a good anti-fouling performance in the filtration of blood solution. No chemical bond was found between PAN and Fe_3O_4 in the membrane at room temperature. The addition of Fe_3O_4 can improve the temperatures of dehydrogenated reaction and decomposition of PAN but dot change the glassy transition temperature. The resistance against acid is stronger than the resistance to base for a PAN- Fe_3O_4 membrane.

结果表明在PAN- Fe_3O_4超滤膜制备过程中使用外加磁场作用能有效提高膜的耐污染能力，这一结果为开发适用于血液处理的耐污染超滤膜提供了一种新途径；在PAN- Fe_3O_4超滤膜中，四氧化三铁与PAN在室温下没有形成化学键，也不存在官能团之间的相互作用；添加Fe_3O_4对膜的玻璃化温度没有影响，但能提高PAN环化脱氢反应的温度和分解温度；PAN- Fe_3O_4超滤膜的耐酸性强于耐碱性，在pH值为10以上的溶液中由于水解作用而溶解，使得膜失去使用价值，膜的耐酸性与酸的种类、浓度和氧化性有关。

B〓C coating possessed 4% of porosity, 12. 8Gpa of bonding strength, 28Gpa of microhardness, and its modulus is up to 230Gpa. It would provide a kind of coating material with excellent properties for many industrial fields.(2) The phase composition of B〓C coating was studied by XPS, XRD and EDS. It was found that: the oxidation activity energy of B〓C powder and coating is different, which is due to the difference of phase composition between them.

If the TBCs system is homogeneous, the TGO will take on relatively regular and periodical undulation. Unfortunately, in actual situation, some abnormal thick areas will be presented in TGO, which is in single-layer or multi-layer form. In SEM, it can be seen that such protrusion areas originate from TGO, and penetrate into bond coat layer gradually with the increment of oxidation time, namely, the oxidation localization phenomenon occurs.

如果体系均匀，则TGO层将表现出较规则的周期状起伏，但在实际服役过程中，TGO层经常出现单个的异常厚部位或多层的异常厚部位，在扫描电镜图上呈现出钉子状或瘤状的局部突起物，这种突起物源于氧化层，并随着高温工作时间的延长向粘结层中扩展，即发生了氧化局域化现象。
