    Abstract: A process for depositing a noble metal on zirconia ceramics is described, which comprises the steps of: inserting an element made of zirconia ceramics and at least one noble metal into a machine for creating vacuum; performing a vacuum operation at a temperature of about 200 °C, through a Physical Vapour Deposition, PVD, technology, thereby ionizing the noble metal into atoms, which melt with the sub-layer of zirconia ceramics, obtaining a surface with high resistance and hardness. A jewellery product made through such process is also described.

    Abstract: A method of manufacture of products from geopolymer composite shaped in a mold which is filled by casting of geopolymer composite in form of a precursor and after its hardening the casting is taken out from the mold and the casting surface is provided with a metallic layer. Before metal-plating casting surface with absorption capacity greater than 5 % is treated to make it chemically stable so that pH of a leachate from 100 g of the bulk product in 1000 g distilled water after 24 hours does not exceed 9. In order to reduce the absorption capacity of the casting surface it is penetrated with polymer substances or particles of a non-porous filler are added into the geopolymer composite in the precursor state. The metallic layer on the casting surface is made by a method from the group of methods that include vacuum deposition, vacuum sputtering, galvanization, cold metal spraying, dip coating in melted metal, plasma spraying of melted metal, deposition of metal from metal salt solution or colloid solution or sintering of powder metal.

    Abstract: The present invention is a technological sequence which is composed of uniaxial freezing with control solution composition, followed by freeze-drying, followed by sintering, and followed by infiltration. The invention enables the manufacturing of functionally graded composites. These composites can include spatially distributed phases of ceramics, metals, polymers, glasses, and their combinations as long as the composite matrix material is originally in the form of powders. During uniaxial freezing, the diameter of crystals growing from the suspension (and, thus, the diameter of the voids formed after freeze-drying) is dependent on the controllable rate of cooling, pressure and the changeable chemical composition of the suspension liquid phase. Thereby a structure with conic voids can be created. After following sintering and infiltration, the produced composite (e.g., ceramic-metal composite) will have a specially distributed concentration of the second phase in the composite matrix, that is, it will have a functionally-graded structure.

    Abstract translation: 本发明是一种工艺流程,其由单轴冷冻和对照溶液组合物组成,然后冷冻干燥,然后烧结,然后渗透。 本发明能够制造功能梯度复合材料。 这些复合材料可以包括陶瓷,金属,聚合物,玻璃以及它们的组合的空间分布相,只要复合基体材料原本是粉末形式即可。 在单轴冷冻过程中,从悬浮液中生长的晶体的直径(以及由此在冷冻干燥后形成的空隙的直径)取决于冷却的可控速率,压力和悬浮液相的可变化学组成。 由此可以创建具有圆锥形空隙的结构。 在烧结和渗透之后,所生成的复合材料(例如陶瓷 - 金属复合材料)将在复合基质中具有特别分布的第二相浓度,即它将具有功能梯度结构。
