I. Product Introduction of Zirconia Ceramic Stepped Shaped Parts:
Zirconia ceramic stepped shaped parts are non-standard ceramic components, usually custom-made according to customer-provided drawings. These products possess the following significant characteristics:
1. High Strength and High Hardness: Zirconia ceramics have a Vickers hardness (HV) exceeding 1300 kg/mm², a bending strength of over 1200 MPa, and a fracture toughness 3-5 times that of traditional alumina ceramics.
2. High Temperature Resistance: They can withstand high temperatures above 1200℃, with a thermal expansion coefficient of 9.6 × 10⁻⁶/K.
3. Corrosion Resistance: They exhibit strong resistance to acids, alkalis, and strong corrosive media, making them suitable for harsh working environments.
4. High-Precision Machining: Machining accuracy can reach ±0.001mm, achieving a mirror-polished surface.
5. Biocompatibility: Non-toxic and harmless, with excellent compatibility with human tissue, making them suitable for medical applications.
II. Application Fields
1. Industrial Manufacturing
Wear-resistant components: Bearings, sealing rings, nozzles, pump parts, etc., with wear resistance 3-5 times higher than metal components.
Cutting tools: Used for processing high-hardness metals and composite materials, improving processing efficiency and accuracy.
2. Medical and Healthcare
Dental Restorations: Dental crowns, bridges, implants, etc., with colors closely matching natural teeth.
Artificial Joints: Hip joints, knee joints, etc., reducing the risk of metal allergies.
Surgical Instruments: High-precision and corrosion-resistant scalpels, forceps, etc.
3. Electronics and Automotive
