“…At present, metallic elements are widely used as stabilizers to accomplish the phase transformation of ZrO 2 at room temperature, including Mg, calcium (Ca), yttrium (Y), cerium (Ce), lanthanum (La), etc. [47][48][49]. For example, Ponnilavan et al [50] investigated the effect of rare-earth substitutions on the performance of ZrO 2 -Al 2 O 3 for biomedical applications and found that the combinations of Gd and Dy in ZrO 2 -Al 2 O 3 displayed better mechanical properties due to the phase transformation.…”

As two promising biomaterials for bone implants, biomedical metals have favorable mechanical properties and good machinability but lack of bioactivity; while bioceramics are known for good biocompatibility or even bioactivity but limited by their high brittleness. Biocermets, a kind of composites composing of bioceramics and biomedical metals, have been developed as an effective solution by combining their complementary advantages. This paper focused on the recently studied biocermets for bone implant applications. Concretely, biocermets were divided into ceramic-based biocermets and metal-based biocermets according to the phase percentages. Their characteristics were systematically summarized, and the fabrication methods for biocermets were reviewed and compared. Emphases were put on the interactions between bioceramics and biomedical metals, as well as the performance improvement mechanisms. More importantly, the main methods for the interfacial reinforcing were summarized, and the corresponding interfacial reinforcing mechanisms were discussed. In addition, the in vitro and in vivo biological performances of biocermets were also reviewed. Finally, future research directions were proposed on the advancement in component design, interfacial reinforcing and forming mechanisms for the fabrication of high-performance biocermets.

“…Transformation from tetragonal to monoclinic is rapid due to the change in temperature. In this transformation, the volume is increased from 3 to 6% thereby making cracks in the material [22]. In a CI engine, operating temperature varies from 600 to 2000°C.…”

This experimental work analyzes the usage of 100% of Waste Plastic Oil (WPO) in low heat rejection (LHR) diesel engine without diesel. For this purpose, the hardware components of conventional diesel engine were coated with lanthana-doped partially stabilised zirconia, to a thickness about 300 μm by plasma spray coating technique. WPO was produced in a research facility scale setup by pyrolysis method. Coated and uncoated engines were tested with WPO and the outcomes were compared with diesel. Results authenticate the objective of this study and shows enhancement in performance and diminution in specific fuel utilization. The reduction in emission with exception of NO x was noticed in lanthana-doped partially stabilised zirconia coated engine than that of uncoated diesel engine.

“…10 Recently, magnesia partially stabilized zirconia ceramics (MgO-PSZ) have become one of the most acceptable refractories in melting of nickel-based super alloy due to its superior high-temperature thermomechanical properties. 11 Since zirconia has the lowest thermal conductivity of any commercial refractory and in the meanwhile MA spinel has received a great deal of attention as a technologically important material due to its attractive properties such as high melting point, high mechanical strength at elevated temperature, high chemical inertness, and good thermal shock resistance, effect of MA addition on stabilization and densification of m-ZrO 2 was deserved to be studied. [12][13][14][15][16] Morita et al reported synthesis of nanocrystalline ZrO 2 -30 vol% MA composite by high-energy ball-milling followed by spark plasma sintering; their study showed that nanocrystallized MA has improved the strength of the composite by a factor of 2.0-2.5.…”

Cubic-stabilized zirconia ceramic composites have been synthesized by conventional sintering, starting from commercial m-ZrO 2 , Y 2 O 3 , and waste-derived magnesium aluminate spinel (MA) powders. In this work, the effect of sintering temperature and MA content on stabilization and densification properties of YSZ have been duly considered. MA-free YSZ0 composite sintered at 1600°C-1700°C revealed m-and t-ZrO 2 dual-phase structure where its m-ZrO 2 was partially stabilized upon temperature rising into tetragonal phase by Y 3+ diffusion inside zirconia structure. YSZ10-50 composites containing 10-50 wt% MA demonstrated dissimilar behavior where their m-ZrO 2 was transformed and stabilized into a cubic form by diffusion of Y 3+ , Mg +2 , and Al +3 inside zirconia lattice. Furthermore, densification of YSZ10-50 powder mixtures by conventional sintering at 1600°C for 2 hours resulted in fully dense compacts with micrometer-sized grains. The outcomes indicate that MA has a significant effect on m-ZrO 2 stabilization into the cubic phase structure at room temperature. In this respect, this study offers huge potentials for developing fully stabilized c-ZrO 2 ceramics that could be possibly used as industrial ceramics for structural applications of harsh chemical and thermal environmental conditions.
