Quelles sont les propriétés mécaniques des pièces en céramique de zircone ?

---

Céramique de zircone, as an advanced structural ceramic material, are highly favored in the industrial field due to their excellent mechanical properties.

Core mechanical performance indicators of zirconia ceramics

1. Dureté et résistance à l'usure extrêmement élevées
   The Vickers hardness of zirconia ceramics can reach 12-13 GPa, much higher than most metals and engineering plastics. This characteristic makes it perform well in environments with severe wear and significantly extend its service life.
2. Excellent fracture toughness
   Compared with ordinary ceramics such as alumina, zirconia can achieve fracture toughness of 8-10 MPa · m ¹/² through phase transformation toughening mechanism, with outstanding impact resistance and reduced risk of brittle fracture.
3. High strength and flexural performance
   Its bending strength is usually 800-1200 MPa, and some yttrium stabilized zirconia (YSZ) can even reach over 1500 MPa, which can withstand high load conditions.
4. Good corrosion resistance and chemical stability
   Has strong resistance to acidic, alkaline, and high-temperature oxidation environments, suitable for long-term operation in corrosive media.
5. Faible coefficient de frottement et propriétés autolubrifiantes
   Smooth surface and low friction coefficient (about 0.1-0.15), suitable for high-precision moving parts.

Typical application scenarios and problems solved
Zirconia ceramic workpieces are widely used in the following fields, solving many problems that traditional materials find difficult to overcome:
-Dispositifs médicaux : surgical blades, dental implants, joint prostheses.
Résolution de problèmes : Excellent biocompatibility, no risk of metal allergies, and wear and corrosion resistance, extending the lifespan of the implant.
-Industrial machinery: sealing rings, bearings, cutting tools, textile ceramic parts.
Résolution de problèmes : Maintain dimensional stability in high-speed, high-pressure, and high-temperature environments, and reduce equipment downtime and maintenance frequency.
-Electronics and Communication: Fiber Optic Connectors, Semiconductor Processing Components.
Résolution de problèmes : Good insulation performance, low dielectric loss, ensuring signal transmission stability.
-Automotive and Aerospace: Sensor Components, Engine Coatings, Turbine Blades.
Solution : High temperature resistance (up to 2400 ℃), reducing component weight and improving fuel efficiency.

Product advantages: Why choose zirconia ceramics?

1. Lifespan and Economy
   Although the initial cost is higher than that of metal, its wear and corrosion resistance can reduce the frequency of replacement, and the long-term total cost is actually lower.
2. Accuracy and stability
   The size change after sintering is small, and it can be processed into high-precision complex shapes, suitable for precision instruments.
3. Multi functional integration
   Performance (such as conductivity and thermal expansion coefficient) can be adjusted through doping modification to meet customized needs.
