Advantages of Nano-Composite Zirconia Ceramic Coating
With the growth of cutting-edge science and technology in fields such as aerospace, electronics, and the military industry, the use of special ceramic coatings has been consistently and rapidly developing in recent years. High-performance coatings, in contrast to monolithic ceramic materials, are able to organically combine the advantages of both metal materials and ceramic materials. The excellent toughness, ease of processing, electrical and thermal conductivity of metal materials can be combined with characteristics of ceramics like high temperature resistance, high wear resistance, and high corrosion resistance, etc., so that the comprehensive advantages of the two can be given into full play. Coatings made of nano-composite ceramics can be applied to a wide variety of base materials, including steel, non-ferrous metals, glass, and resin plates, and so forth. Among ceramic coatings, the nanocomposite zirconia ceramic coating presents excellent heat insulation and great high-temperature resistance. It is a kind of special ceramic coating material with a wide range of applications and a comparatively developed technology.
Nano-composite zirconia ceramic coatings, when seen from the perspective of the direction in which their development is going, are utilized not only in high-end fields such as the military industry, but also in the civilian fields, which are actively trying to apply those advanced nano-technologies to the production of products. The following are some of the benefits that nanocomposite ceramic coatings offer:
(1) Make the advantages of metal and ceramics complement each other;
(2) It can fulfill the needs of unique performance and special working conditions;
(3) The shape and size of the workpiece and the economic benefits are desirable.
Preparation of Nano-Composite Zirconia Ceramic Spray Powder
The preparation of nanocomposite zirconia ceramic spraying powder involves "two controls, one selection and one treatment", in which "two controls" refer to the controls of purity and impurities, as well as crystal particle size (nano-level) and temperature of nanocomposite zirconia ceramic spraying powder; "one selection" refers to the choice of solid-liquid separation and additives in the preparation process; and "one treatment" refers to powder dispersion and interface treatment.
Spraying Equipment
While choosing spraying equipment for the creation of nanocomposite zirconia ceramic coatings, it is important to ensure that the functional systems are well matched, and the power and stability should be taken into consideration as well.
Spraying Process and Coating Post-Treatment
In the application of nano-composite zirconia ceramic spray powder, the spraying process and coating post-treatment are also significant elements. It is important to pre-treat workpieces, regulate workpiece temperature, adjust spraying power and distance, manage powder feeding and feeding rate (deposition rate), etc. Last but not least, hole sealing treatment is necessary to prolong the workpiece's service life.
Common Application of Nano-Composite Zirconia Ceramic Coating
Nanocomposite zirconia ceramic coatings are frequently utilized in corrosion prevention, isolation, and thermal barrier coatings.
Low-Cost Application of Nano-Composite Ceramic Coating
(1) It is appropriate for high-temperature functional coatings on metals, graphite, ceramics, ceramic fibers, and glass surfaces.
(2) It is appropriate for special function ceramic coatings on metal, graphite, ceramic, ceramic fiber, glass, and wood surfaces at room temperature.
In addition to zirconia ceramic mobile phone cover plates and zirconia ceramic teeth, nanocomposite zirconia ceramic coatings are undeniably a focus for the increasingly popular zirconia area. The ongoing development of nano-ceramic coatings has significantly decreased the cost of coating applications for businesses and has the potential to enhance the performance of their products.
