    • A ceramic composite material comprises a ceramic material constituting a matrix, and dispersion particles disposed in the matrix in a dispersing manner. A specific shape of a ceramic composite material is, for instance, a sinter or a thermally sprayed layer. The dispersion particles are consisting of a composite oxide including at least one kind of a first metallic element selected from alkaline earth metals such as Mg and Ca, and at least one kind of a second metallic element selected from W, Ti, Ta, Mo, Nb, V, B, Te, Ge and Si, for instance, are composite oxide particles precipitated by reacting a compound containing a first metallic element and a compound including a second metallic element through heat treatment. The precipitated particles consisting of such a composite oxide can be dispersed as planar particles or acicular particles in the ceramic layer to which, for instance, thermal spraying is applied. The dispersion particles suppress deterioration of strength or toughness of the oxide based ceramic material under high temperature atmosphere.
    • 陶瓷复合材料包括构成基体的陶瓷材料和以分散方式设置在基质中的分散粒子。 陶瓷复合材料的特定形状是例如烧结体或热喷涂层。 分散粒子由包含选自碱土类金属如Mg和Ca中的至少一种第一金属元素和选自W,Ti,Ta,Mo中的至少一种第二金属元素的复合氧化物组成, 例如,Nb,V,B,Te,Ge和Si是通过热处理使包含第一金属元素的化合物和包括第二金属元素的化合物反应而沉淀的复合氧化物颗粒。 由这种复合氧化物构成的沉淀粒子可以作为平面粒子或针状粒子分散在例如进行热喷涂的陶瓷层中。 分散颗粒抑制氧化物基陶瓷材料在高温气氛下的强度或韧性的劣化。

    • A heat-resistant member is constructed by having a ceramic coating layer deposited on the surface of a metallic substrate through the medium of a metallic bonding layer. The metallic bonding layer is composed of at least two layers, i.e. a layer of an aggregate of minute particles disposed on the metallic substrate side and a layer of an aggregate of coarse particles disposed on the ceramic coating layer side. Otherwise, the metallic bonding layer is composed of at least three layers, i.e. two layers of an aggregate of coarse particles disposed one each on the metallic substrate side and the ceramic coating layer side and one layer of an aggregate of minute particles interposed between these two layers of an aggregate of coarse particles. These layers are obtained by the low pressure ambient plasma thermal spraying using a fine powder or a coarse powder of an alloy resistant to corrosion and oxidation. The metallic bonding layer constructed as described above is excellent in the ability to resist high temperature oxidation and high temperature corrosion and stable to tolerate thermal fatigue and thermal impacts. Thus, it is capable of preventing the thermal barrier coating layer from sustaining cracks or inducing film separation.
    • 通过在金属基材的表面上通过金属粘合层的介质沉积陶瓷涂层而构成耐热构件。 金属接合层由至少两层构成,即设置在金属基板一侧的微小颗粒聚集体层和设置在陶瓷涂层侧的粗粒子集合体层。 另外,金属接合层由至少三层构成,即,在金属基板一侧和陶瓷涂层侧分别设置两层的粗粒子的集合体和一层在这两者之间插入的微粒子集合体 一层粗粒子的聚集体。 这些层通过低压环境等离子体热喷涂获得,其使用耐腐蚀和氧化的合金的细粉末或粗粉末。 如上所述构成的金属接合层,耐高温氧化和高温腐蚀的能力优良,耐热疲劳和热冲击性能稳定。 因此,能够防止热障涂层维持裂纹或引起膜分离。
