Combining Metal Toughness With Ceramic Hardness Zirconia Ceramics For High-Performance

Combining Metal Toughness With Ceramic Hardness Zirconia Ceramics For High-Performance

Product Description

This product is precision-engineered from high-performance Zirconia (ZrO2) ceramic material, specifically designed to withstand extreme and demanding operating environments. Its unique polycrystalline structure grants it unparalleled comprehensive properties, combining the toughness of metal with the hardness of traditional ceramics. It is an ideal material for manufacturing critical components such as high-precision bearing rings, advanced insulating rings, and corrosion-resistant structural supports. Whether your equipment faces high-speed wear, chemical corrosion, or high-temperature challenges, this product provides a durable and stable solution.

Key Advantages

• Ultra-High Strength & Toughness: Flexural strength exceeding 1000 MPa. Its unique phase transformation toughening mechanism effectively prevents crack propagation, fundamentally changing the perception of traditional ceramics being brittle.

• Exceptional Wear Resistance: Hardness second only to diamond, with a low friction coefficient. It performs excellently under unlubricated or poorly lubricated conditions, with a service life dozens of times longer than metal parts.

• Excellent Temperature Resistance & Insulation: Withstands temperatures up to 1500°C. Its thermal expansion coefficient is close to that of metal, facilitating easy assembly with metal components, while also offering excellent thermal insulation.

• Outstanding Corrosion Resistance & Electrical Insulation: Resists corrosion from most acids, alkalis, and organic solvents, while maintaining stable high insulation resistance, ensuring safe operation in complex electromagnetic environments.

Primary Applications

• Precision Machinery: High-speed spindle bearing rings, balls, guides, support members for measuring instruments.

• Electronic Equipment: Insulating rings in semiconductor manufacturing equipment, vacuum chucks, RF windows.

• Chemical & Medical Industries: Pump and valve seals, reactor linings, medical implants, and surgical tools.

• High-Temperature Environments: Furnace supports, thermocouple protection tubes, thermal insulation components for aerospace engine applications.

Process Flow

We adhere to precision manufacturing standards. The process includes: Nanoscale Powder Preparation → Precision Dry Pressing/Isostatic Pressing → High-Temperature Atmosphere Sintering → CNC Precision Grinding/Polishing → Laser Non-Destructive Testing → 100% Cleaning & Packaging. This ensures dimensional accuracy and performance consistency for every single product.

Usage Instructions

• Installation Advice: It is recommended to use non-metallic tools (e.g., nylon, copper) for assembly to avoid localized stress concentration and potential damage. When designing interference fits with metal parts, please specify reasonable tolerances.

• Operating Environment: Avoid severe impact with hard particles. Consider its thermal shock limit in applications with rapid temperature changes.

• Cleaning & Maintenance: Ultrasonic cleaning is suitable. The use of neutral or mild cleaning agents is recommended.

After-Sales Service

We are committed to providing comprehensive support: Free sample testing (conditions apply), professional technical consultation from application engineers, rapidly responsive customized solutions, and a thorough quality tracking and assurance system. We are dedicated to being your reliable strategic partner.

FAQ

• Q: What are the advantages of zirconia ceramic bearings compared to all-steel bearings?

  • A: The main advantages include lighter weight (up to 60% reduction), non-magnetic properties, electrical insulation, self-lubrication, corrosion resistance, and higher operational speeds, significantly enhancing equipment performance and lifespan.

• Q: What dimensional accuracy and tolerances can be achieved for the parts?

  • A: Leveraging advanced CNC machining capabilities, we can consistently achieve high precision at the ±0.001mm level. Specific tolerances depend on part size and structure. We welcome discussions based on your drawings.

• Q: Is small-batch custom production available?

  • A: Yes. Our flexible production model allows us to efficiently respond to orders ranging from R&D samples to small and medium-volume batches.
