WEAR REESISTANCE OF NANOSTRUCTURED AND CONVENTIONAL YTTRIA-STABILIZED ZIRCONIA COATINGS
Partially stabilized zirconia (PSZ) has been proven to be an excellent candidate as a thermal barrier coating (TBe) for hot sections in, for instance, heat or internal combustion engines and gas turbine parts. The main functions of these coatings are reducing heat losses, reducing fuel consumption, increasing efficiency, and extending durability and life. One of the main problems involved is we...
متن کاملRadiation Tolerance of Nanocrystalline Ceramics: Insights from Yttria Stabilized Zirconia
Materials for applications in hostile environments, such as nuclear reactors or radioactive waste immobilization, require extremely high resistance to radiation damage, such as resistance to amorphization or volume swelling. Nanocrystalline materials have been reported to present exceptionally high radiation-tolerance to amorphization. In principle, grain boundaries that are prevalent in nanoma...
متن کاملFracture toughness of yttria-stabilized zirconia sintered in conventional and microwave ovens.
STATEMENT OF PROBLEM The fabrication of zirconium dioxide (ZrO2) dental prosthetic substructures requires an extended sintering process (8 to 10 hours) in a conventional oven. Microwave sintering is a shorter process (2 hours) than conventional sintering. PURPOSE The purpose of this study was to compare the fracture toughness of 3 mol % Y2O3-stabilized ZrO2 sintered in a conventional or micro...

متن کاملEffect of impurities on sintering and conductivity of yttria-stabilized zirconia
The effect of low concentrations of Fe203, AI203 and Bi203 on the sintering behaviour of (ZrO2)o.83 (YO1.s)o.17, made by alkoxide synthesis, has been investigated. The best results are achieved with Bi203 as a sinter agent and a relative density of 95% is obtained at 1200 K. The effects of these impurities on the electrical conductivity of the bulk and the grain boundaries has been investigated...
