Ceramic Pump Seal Plate Seal Disc Zirconia Ceramic Automobile Pump Component Anti-abrasion Wear Resistance

Part Name: ceramic pump seal/zirconia seal plate

Specifications: φ47mm*H1.5mm

Materials: Yttria-stabilized zirconia

Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. After shaping and sintering, Yttria-stabilized zirconia’s hardness reaches HV2500, and has good properties as wear resistance, anti-corrosion, high temperature resistance, as well as excellent finish surface.

Microstructure of a ZrO2 ceramic

Properties:

Powerful interatomic bonds endows zirconia ceramics not only with high hardness and wear resistance, but also a resistance to corrosion. Usually it has less hardness and brittleness than that of alumina ceramic, but has more elasticity, which means it is not as brittle as alumina ceramic. If hardness is not so exacting, zirconia parts are a good choice to be applied.

Advantages of zirconia parts:

·High wear, heat, pressure, and chemical attack resistance (gas and liquids)

·Extreme hardness

·Excellent electrical insulation

·Relatively lightweight

Application: Because zirconia has good properties of elasticity module and high hardness, as well as the above good properties, the parts made from zirconia are often used as mechanical or pump seal plate or disc.
