High hardness and fine processing of zirconia ceramic structural parts

Overview of Zirconia ceramic structural parts

Zirconia ceramic structural parts are ceramic parts with specific structures made of zirconium oxide powder as the main raw material through molding, sintering and other processes. It has many excellent properties, such as high hardness, second only to diamond, and can resist various types of wear and high toughness, making it not easy to break when impacted.

At the same time, it also has excellent high-temperature resistance, can work stably in extremely high-temperature environments, has excellent antioxidant and corrosion resistance, and is not easily corroded by various chemical substances. These characteristics make zirconia ceramic structural parts widely used in many fields, such as aerospace, machinery manufacturing, and the electronics industry. It provides a reliable choice for high-precision, high-performance equipment components and has strongly promoted technological progress and product upgrades in related industries.

Features of Zirconia ceramic structural parts

Zirconia ceramic components have many excellent properties. Zirconia ceramic components have high hardness and high wear resistance, with a Mohs hardness of about 8.5, almost the same as sapphire, which makes it perform well in high-friction environments and can significantly extend the service life of components. At the same time, zirconia ceramic components also have good toughness, with a fracture toughness of 1-3.5MPa·m¹/², which makes it difficult to break when subjected to large external impacts and can maintain the integrity of the structure.

In addition, zirconia ceramic structural parts have excellent high-temperature resistance, with a melting point of up to 2715°C. They can still maintain stable performance in high-temperature environments without softening or deformation. Zirconia ceramic structural parts also have good biocompatibility and will not cause rejection reactions in the human body. Therefore, they have been widely used in medical fields such as dental restoration and artificial joints. In terms of electrical properties, zirconia ceramics are insulators at room temperature but have certain conductivity at high temperatures, which makes them play a key role in special electronic components and sensors such as oxygen sensors and solid oxide fuel cells.

5 FAQs of Zirconia ceramic structural parts

Q1:Are zirconia ceramic components easily broken by vibration?|

Although zirconia ceramic components are ceramic materials, they have high toughness and impact resistance. Under normal working conditions and reasonable structural design, they will not be easily broken by vibration. However, when designing and using them, their working environment and stress conditions must still be considered to ensure their safety and reliability.

Q2:How difficult is the processing of zirconia ceramic structural parts?

Zirconia ceramic components are difficult to process, mainly due to their high hardness and brittleness. During the processing, special processing equipment and tools, such as diamond tools, are required, and the processing parameters must be strictly controlled to avoid processing defects. In addition, the processing cost of zirconia ceramics is relatively high.

Q3:What are the advantages of zirconia ceramic structural parts compared with alumina ceramics？

The bending strength and fracture toughness of zirconia ceramic components are better than those of alumina ceramics. The bending strength can reach 1200MPa, and the fracture toughness can reach 8-12MPa·m½, while the bending strength of alumina ceramics is generally 300-400MPa, and the fracture toughness is about 3-4MPa·m½. Therefore, zirconia ceramic components have better performance when subjected to impact and bending loads and are suitable for some occasions with high requirements for strength and toughness.

Q4:What are the advantages of zirconia ceramic structural parts compared with metal materials？

Compared with metal materials, zirconia ceramic structural parts have higher hardness and wear resistance, can effectively resist wear and corrosion, and extend service life; at the same time, its density is relatively small, about 1/2-1/3 of that of metal materials, which can reduce equipment weight and energy consumption. In addition, zirconia ceramics have good insulation properties and biocompatibility and have unique advantages in the fields of electronics, medical treatment, etc.

Q5:What is the oxidation resistance of zirconia ceramic structure?

Zirconia ceramic structural parts have good oxidation resistance and can remain stable even in high-temperature environments without oxidation reactions, ensuring that their performance is not affected. They are suitable for use as high-temperature components, such as high-temperature components in aerospace engines.
