Zirconia Driven Shaft Zirconia Ceramic Rod or Stick Aerocraft Engine Component High Temperature Resistance
The zirconia shafts are made from high purity zirconia ceramics, which has excellent properties like high-temperature resistance (up to 1200℃), lower thermal conductivity (only 4 W/m.k at room temperature) than alumina ceramic parts, great flexural strength more than 2 times higher than alumina ceramic parts, as well as nearly zero dielectric constant. Also after being polished, it can achieve much better roughness by comparing alumina ceramic parts.
Yttria-stabilized zirconia provides such benefits as substantial increase shaft life by reducing abrasion, significant reduction in noise (in most cases), USDA approval for contact with food products. If price is not concerned, yttria-stabilized zirconia is a better material option than alumina ceramics.
Suzhou Jingci Super Hard Materials Co.,Ltd, specializes in precision ceramics for more than 20 years and has rich experiences in designing and developing technical ceramic solutions for a wide variety of applications. At present, Jingci owns more than ten production lines, bearings and shafts made from ceramics can be machined in high volume to micron precision tolerances using state of the art diamond processing and grinding wheel technology. For example, an alumina ceramic rod with dimensions φ8mm*L80mm , 0.5μm roundness, 3μm straightness and 12μm OD tolerances can be achieved in mass production.
