Application of ZTA ceramic

ZTA ceramic (Zirconia-Toughened Alumina ceramic), a composite ceramic that combines alumina’s high hardness/wear resistance with zirconia’s toughness/thermal shock resistance, is widely used in wear-resistant engineering, automotive, mining, and medical fields. Its specific applications are as follows:

1. Wear-Resistant Engineering & Industrial Machinery (Core Application)

• Mechanical Seals & Pump Parts: Used to manufacture mechanical seal faces (for centrifugal pumps, slurry pumps) and pump impellers. Its high hardness (Mohs 9.1, higher than pure alumina) and enhanced toughness (fracture toughness ~6 MPa·m¹/², 2–3 times that of alumina) resist wear from high-speed fluids and solid particles, extending seal life by 4–6 times compared to metal or pure alumina seals.

• Abrasive & Grinding Components: Produces grinding balls, liners for ball mills, and sandblasting nozzles (for mining, building materials). It has low wear rate (0.02–0.05%/1000h) and high impact resistance, suitable for grinding hard materials (ores, ceramics, glass) without contaminating the raw material (no metal ion precipitation).

• Conveyor & Pipeline Parts: Makes ceramic liners for material conveyors (belt conveyors, screw conveyors) and elbow liners for pneumatic conveying pipelines. It withstands impact from bulk materials (coal, gravel) and reduces friction, solving the problem of rapid wear in traditional metal pipelines.

2. Automotive Industry (High-Stress Components)

• Engine & Transmission Parts: Applied in engine valve guides, cam followers, and transmission synchronizer rings. Its high-temperature resistance (long-term use up to 1200°C) and wear resistance reduce friction between moving parts, improving engine efficiency and extending service life (e.g., valve guide life up to 300,000 km).

• Brake System Accessories: Used as a reinforcement phase in ceramic brake pads and lightweight brake disc inserts. It enhances the brake pad’s high-temperature stability (resists fading at 800–1000°C) and reduces brake noise, while its low density (3.7–3.9 g/cm³) helps reduce vehicle unsprung mass.

• New Energy Vehicle (NEV) Components: Manufactures insulating sleeves for high-voltage cables and wear-resistant rings for battery cooling systems. Its electrical insulation (volume resistivity ≥10¹⁴ Ω·cm) and corrosion resistance (resistant to coolant/electrolyte) adapt to the NEV’s high-voltage and humid environment.

3. Mining & Construction Equipment

• Mining Drill Bits & Cutting Tools: Produces inserts for rock drill bits (tunneling, mining) and cutting teeth for roadheaders. Its high compressive strength (≥3500 MPa) and impact toughness resist fracture when drilling hard rock (granite, basalt), doubling the drill bit’s service life compared to cemented carbide.

• Construction Machinery Parts: Makes wear plates for excavator buckets, crusher jaw plates, and concrete pump piston cups. It withstands abrasion from sand, gravel, and concrete, reducing the frequency of part replacement (e.g., excavator bucket liner life up to 2000 working hours).

4. Medical & Biomedical Field

• Orthopedic Implant Components: Used in artificial joint spacers and bone fixation plates. Its high biocompatibility (no toxic impurities) and wear resistance (wear rate < 0.08 mm³/10⁶ cycles) avoid tissue rejection and long-term wear debris, suitable for patients with high activity levels.

• Dental & Surgical Tools: Manufactures dental crown frameworks (for posterior teeth) and surgical reamers (for bone drilling). Its hardness ensures chewing resistance (for crowns) and drilling precision (for reamers), while its smooth surface is easy to sterilize (resistant to 134°C autoclaving).

5. Other Special Fields

• Aerospace Auxiliary Parts: Applied as wear-resistant liners for aircraft landing gear components and insulation sleeves for engine fuel nozzles. Its lightweight and high-temperature stability meet the strict weight and performance requirements of aerospace equipment.

• Electronic Equipment Parts: Makes heat dissipation substrates for high-power LEDs and insulating washers for industrial inverters. Its thermal conductivity (~25 W/(m·K)) and insulation balance heat dissipation and electrical safety, suitable for high-power electronic devices.
