Ⅰ.Zirconia Ceramic High-Strength, Wear-Resistant Precision Components Product Introduction:
Zirconia ceramic (ZrO₂) is an ideal material for high-precision components due to its excellent physical and mechanical properties:
1. Ultra-high hardness and wear resistance: Mohs hardness reaches 9.0-9.5 (second only to diamond), Vickers hardness HV 1200-1500, and wear resistance far exceeds that of metals, extending service life by 5-10 times.
2. Excellent mechanical strength: Bending strength up to 750-1200 MPa, fracture toughness up to 6-15 MPa·m¹/², and crack propagation is inhibited through a phase transformation toughening mechanism (tetragonal phase → monoclinic phase).
3. Other characteristics: High melting point (2715℃), excellent corrosion resistance and thermal stability.
Ⅱ.Application Fields
Zirconia ceramic precision components are widely used in several demanding fields:
1. Industrial Manufacturing: Key components such as bearings, sealing rings, nozzles, and cutting tools.
2. New Energy: Lithium battery electrode rolling bearings (resistant to electrolyte corrosion), core components of liquid injection pumps (zero metal ion contamination).
3. Semiconductors: Vacuum robotic arm fingers (zero particle shedding), CVD equipment nozzles (resistant to plasma corrosion), photolithography machine positioning components (thermal deformation <0.1μm).
4. Medical Equipment: CT scanner slip ring components (100,000 hours maintenance-free), surgical robot transmission components (biocompatibility certified).
5. 3C Electronics: Mobile phone CNC machining fixtures (eliminating 0.01mm level deformation), screen laminating machine suction cups (surface roughness Ra0.02μm).
6. Automotive Industry: LiDAR rotating mirrors (resistant to vibration deformation), hydrogen fuel cell bipolar plates (integrated conductivity and corrosion resistance).
7. Aerospace: Satellite attitude control bearings (non-volatile in vacuum), aero-engine probes (resistant to 1500℃ thermal shock).
8. Energy and Chemical Industry: Oil and gas exploration valves (resistant to H2S corrosion), nuclear power plant mechanical seals (resistant to radiation aging).
9. Meeting Industry Standards: Certified by SEMI, FDA, IATF 16949, and other industry standards.
