High-purity alumina ceramic gears High-hardness, high-temperature and wear-resistant zirconia ceramic gears
Ceramic gears and ceramic structural parts produced by Mingrui Ceramics
Performance advantages of alumina ceramic gears:
· Wear resistance: Alumina ceramics have high hardness, so the gears made have excellent wear resistance.
· High temperature resistance: Alumina ceramics can maintain stable performance in high temperature environments and are not easy to deform or damage.
· Corrosion resistance: It has excellent corrosion resistance to a variety of chemicals and is suitable for corrosive environments.
Performance advantages of zirconia ceramic gears:
· High strength: Zirconia ceramics have extremely high strength, so that the gears made of it can withstand greater loads.
· Good toughness: Compared with other ceramic materials, zirconia ceramics have better toughness and are not easy to break.
· Wear resistance: It also has high wear resistance and is suitable for long-term high-load operation.
Application fields of alumina and zirconia ceramic gears
Alumina ceramic gears are widely used in mechanical equipment, industrial equipment and other fields, especially in places where high wear resistance, high temperature resistance and corrosion resistance are required.
In industries such as food machinery and textile machinery, alumina ceramic gears are favored for their non-toxic and corrosion-resistant properties.
Zirconia ceramic gears are widely used in aerospace, automobile manufacturing, precision instruments and other fields, especially in occasions where material performance requirements are extremely high.
Zirconia ceramic gears can maintain stable performance in harsh environments such as high temperature, high pressure and high corrosion.
