Metallized surface of zirconia ceramic and preparation method

Abstract

The invention relates to a metallized surface of zirconia ceramic and a preparation method. The metallized surface of zirconia ceramic comprises of the following components by weight: 50-70% Mo powder, 11-19% of Mn powder, 6-14% of SiO2 powder, 0.2-2.5% of CaO, 5-15% of 75% alumina ceramic powder, 0-4% of ZrO2, and 0-5% of TiO2. Specifically, the 75% alumina ceramic powder is composed of the following components by weight: 73-79% of Al2O3, 11-17% of SiO2, 0-5% of BaO, 0.5-4% of CaO, and 0.5-2.5% of MgO. The preparation method includes: 1) conducting weighing and mixing according to the metallized formula proportion, placing the mixture in a high energy ball mill, carrying out high-energy ball milling for over 180h in an organic medium to prepare metallized powder; 2) adding a proper amount of an organic binder into the prepared metallized powder, fully stirring them, covering a cleaned zirconia ceramic surface with the mixture by means of silk screen printing, pad printing, spraying coating, pen coating or other modes, and performing natural drying or infrared ray drying; 3) sintering the metallized powder-covered zirconia ceramic under protection of a weak reducing atmosphere; and 4) subjecting the sintered product to nickel plating, thus obtaining a zirconia ceramic surface metallized product.

AI Technical Summary

Benefits of technology

This patented technology describes an improved method for producing highly pure ceramically colored surfaces that can be applied on various materials like ZrC or other oxides without losing their effectiveness over time due to factors like temperature changes (temperature affecting how well it works). These methods allow for precise adjustment of parameters during manufacturing processes while maintaining stability and reliance from each material' characteristics.

Problems solved by technology

This patents describes how strong connections may occur when connecting materials like zircite ceramic with steel without losing their effectiveness due to poor sealing performance caused by an oxidation process that occurs over time. Additionally, there exist methods for joining these components securely through physical contact instead of relying on adhesive bonds which could lose its ability if exposed to moisture. Therefore, researchers aiming to study better ways to connect ziriconcer ceramisms to iron substrates while maintaining sufficient air pressure within the joints themselves.
