An official website of the United States government. The monoclinic content rose on the surface of three zirconia heads which were retrieved at revision. However, in erosive wear environments such as those caused by an abrasive slurry impacting a wear part such as an oilfield valve, Zirconia can be the best performer. Zirconia as a sliding material: histologic, laboratory, and clinical data. Although alumina has been used in orthopaedic surgery since the 1970s, the long-term clinical results of zirconia have not been well documented in vivo. The toughness of zirconia ceramics is about 4 times that of alumina ceramics. We will custom-manufacture products to suit your needs.
They are a very important structural ceramic that is newly developed next to alumina ceramics.

Morrison TA, Moore RD, Meng J, Rimnac CM, Kraay MJ. This site needs JavaScript to work properly. Do you have any questions? Although its commonly accepted that hardness equates with wear resistance, its not always the case. When running an engineering ceramic against a dissimilar material its not always the case that the softer material performs poorly. Although its beyond this article to delve too deep into the tribology of ceramic interfaces, in Zirconia on Zirconia contact its the low thermal conductivity of the Zirconia that can be a negative factor, as the frictional heat generated in like on like sliding does not dissipate from the surface and the surface hardness decreases with a follow on increase in wear-related damage. In addition, the toughness of the zirconia ceramic structural member is excellent, overcomes the inherent brittleness of the ceramic itself.
