Zirconia Ceramic Gear

Zirconia ceramic gear has high hardness and strength, which enables it to withstand heavy loads and resist wear and abrasion. This leads to a longer service life compared to traditional gears made of materials like steel.Zirconia ceramics have low thermal expansion coefficients, which helps maintain the gear's dimensional stability at different temperatures, reducing the risk of thermal distortion and improving its performance accuracy.

Products Description

Zirconia ceramic gears, a premier example of advanced structural ceramics, are high-performance mechanical transmission components manufactured using zirconium dioxide (ZrO₂) as the primary material, also known as zirconia, zirconium oxide, or ZRO2. Through advanced powder processing and sintering techniques (like injection molding zirconia), they possess a dense microstructure. This zirconia ceramic material offers a unique combination of exceptional mechanical properties, wear resistance, and chemical stability, making it an ideal choice for replacing traditional metal or plastic gears in demanding applications. It is distinct from other ceramics zirconia types like alumina, though often combined in composites such as alumina toughened zirconia (ZTA) or zirconia toughened alumina ceramics.

Products Performance

High Strength & Toughness: Particularly, yttria stabilized zirconia (YSZ), specifically yttria stabilized tetragonal zirconia polycrystal (Y-TZP or YTZP), exhibits superior properties. Other grades like magnesia partially stabilized zirconia (Mg-PSZ) and calcia stabilized zirconia also offer high performance. This makes them significantly tougher than other ceramics, reducing brittle fracture risk.
Excellent Wear Resistance: The extreme hardness of materials like black zirconia ceramic and fully stabilized zirconia minimizes wear, ensuring long life for components like ceramic piston pumps and ceramic plunger pumps.
Outstanding Corrosion Resistance: As a chemical zirconia material, it is inert to most corrosive agents, perfect for ceramic seal rings and ceramic pump parts.
Heat Resistance: Maintains properties at high temperatures, suitable for zirconia crucible and zirconium oxide crucible applications.
Non-magnetic & Electrically Insulating: Ideal for ysz substrates and components in electronics.
Low Density: Lighter than steel, beneficial for high-speed zirconia ceramic components.
Biocompatibility: Grades like yttria stabilized zirconia YSZ are suitable for medical custom zirconia parts.
