PMC 2007 Feb;22(2):251-7. doi: 10.1016/j.arth.2006.03.004. Alumina is Harder than Zirconia, So It Must be More Wear Resistant. 8600 Rockville Pike He welcomes feedback on typos, errors, or differences in opinion that readers come across. During the same 12-year period there was, however, no significant change in the rate of wear in the alumina group (0.07 mm/year). The toughness of zirconia ceramics is about 4 times that of alumina ceramics.
To ground down same thicknesses for zirconia takes almost 10x more time than alumina and consume more diamond tools. Federal government websites often end in .gov or .mil. Would you like email updates of new search results? Wear Debris Characterization and Corresponding Biological Response: Artificial Hip and Knee Joints.

If the two ceramic materials are free to fall from the height of one meter at the same time, the zirconia will only have some gaps, but the alumina will be broken. official website and that any information you provide is encrypted Nine MJ, Choudhury D, Hee AC, Mootanah R, Osman NAA. 
Disclaimer, National Library of Medicine However, it is the cost for shaping zirconia that contributes the major part. Cost for zirconia is more than doubled for even the best alumina material. Bethesda, MD 20894, Web Policies 2018 Feb;14(1):60-66. doi: 10.1007/s11420-017-9579-z. In sliding wear environments, hard counter faces that do not interact with each other are an advantage. The use of zirconia can further extend the life of the equipment and greatly reduce losses. 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.
Zirconia ceramic structural parts have a higher surface finish. Unable to load your collection due to an error, Unable to load your delegates due to an error. Our aim was to compare the two ceramics. Zirconia as a sliding material: histologic, laboratory, and clinical data. However, the high cost limits its application and leave most of the market to alumina. Alumina is a very common technical ceramic material. Zirconia could survive longer in highly corrosive environment and is considered better material in chemistry laboratories. Density of zirconia is much higher than alumina and wear resistance of zirconia is far better than alumina. Although zirconia could withstand higher temperature, application in industry furnace is rare. Ceramics for total hip replacement--what a surgeon should know. alumina

The engineering grades of Alumina are typically 25-50% harder than zirconia grade so in sliding wear environments or pure abrasive wear, where third body abrasive wear particles are present, alumina often outperforms Zirconia. Due to its good properties (such as its fracture toughness is higher than alumina ceramics), zirconia ceramic structural parts have received more and more attention. thickness A change in the roundness with an increase in the sphericity deviation was also observed both in the articular and non-articular parts of the femoral heads. One of the reasons is the cost of the raw material. J Bone Joint Surg Br. MeSH The most significant difference between these two materials is the price. Zirconia, including yttrium stabilized zirconia (YSZ), is also widely used in machinery industries. Otherwise, we may not be able to process your inquiry. government site. Because the size of the alumina and zirconia heads was different, hips with 32 mm alumina heads and those with 28 mm zirconia heads were compared with control hips with stainless-steel heads of the same size.

In addition, the toughness of the zirconia ceramic structural member is excellent, overcomes the inherent brittleness of the ceramic itself. 2019 Aug 1;62(4):249-258. doi: 10.1503/cjs.013118. The increase in rate of wear in the zirconia group was only evident after eight years and may be linked to a long-term biodegradation of zirconia in vivo, associated with the altered roughness and roundness which was observed on the retrieved heads. The wear resistance is higher, the service life of the product is greatly prolonged, and the quality is obviously improved.
Y-TZP running against Y-TZP has been shown to be a very poor wear surface combination, whereas, Y-TZP running against cast iron provides a better overall wear performance than the harder, alumina/cast iron combination. How to Improve the Properties of Tungsten Copper Alloy. 2014 Feb 10;7(2):980-1016. doi: 10.3390/ma7020980. Zirconia is generally better in mechanical applications but alumina is a better bullet proof material due to the lower density.
As the wear resistance for zirconia is much better, it is frequently used as mortar and pestles, grinding jars and grinding media, bearing balls and ceramic parts in valves and pumps.
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.
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. His main purpose in writing these articles is to provide a free, yet quality resource for readers. Clin Orthop Relat Res.
