The paper can be divided into three parts . in the first part , the international achievement of cermet thin film study is reviewed , which includes the technology of preparing the thin films , microstructure analysis , and influence of the size , shape and distribution of metal particles on the optical and electrical properties of cermet films 论文分三个部分，在绪论部分，我们综述了上世纪七十年代到本世纪初国内外科研人员对金属陶瓷复合膜制备及光电性质研究的报道，特别关注了复合薄膜中金属颗粒的尺寸、形状及空间分布对薄膜的电学、光学等性质影响的情况。
The results also indicate that by taking particle size effect into consideration , the theoretical values of optical constants of the cermet films are more consistent with experimental values . at last we discuss the discrepancy between the theoretical results and the experimental results , and the factors that cause the discrepancy are analyzed as well 但是我们又发现对纳米金属陶瓷薄膜材料的光学常数的计算，考虑尺寸效应和极化因子修正后的值与实验结果之间仍存在一定的差异，文章最后我们分析讨论了产生这些差异的原因。
The fractured surface morphology of the cermets were observed by a scanning electron microscope ( sem ) . results showed that the ysz - ni - cr and ysz - ni - v cermets had a better wettability than the ysz - ni cermet while the wettability of ysz - ni - mo cermet was worse . the grain sizes of the ysz - ni - based cermets sintered by hot - pressing technique were about 0 . 3 rn with a homogeneous microstructure and uniform distribution 用sem观察了所制备的ysz - ni系列金属陶瓷的断面形貌，结果表明:金属cr和v的引入对金属相和ysz基体的润湿起到了改善的作用，而引入金属mo对ysz一ni的润湿性没有起到改善作用;热压烧结后ysz一ni系列金属陶瓷的晶粒大小和分布十分均匀，晶界清晰，粒度在0 . 3卜m左右。
As the position , intensity and width of the plasma resonance absorption peak are concerned , we find that maxwell - garnett and ping sheng theories are applicable for the cermet films with low metal volume fraction , while bruggeman theory fits better than maxwell - garnett theory for au - mgf2 films with high metal volume fraction 就金属颗粒表面等离子共振引起的吸收峰的峰位、强度和峰形而言，对低金属组分的纳米金属陶瓷薄膜光学常数的计算， maxwell - garnett和pingsheng要比bruggeman理论结果好。
With thermal spray technology , the surface of water wall tubes is easily covered by varied high performance coatings . in this paper , several new alloy and cermet coatings applied to water wall tubes were designed and their performance was studied according to the research item of hanchuan power station of hubei province " the study and development on the corrosion - resistant and wear - resistant coatings of water wall tubes in boiler " 采用热喷涂技术可以方便地在锅炉管道表面获得各种高性能的防腐耐磨涂层。本文结合湖北省汉川电厂的研究项目“锅炉水冷壁管防腐耐磨涂层的开发研究”进行水冷壁管新型合金和金属陶瓷复合涂层的设计和性能研究。
