A ZrO 2 thin film as a corrosion protective layer was deposited on Zircaloy-4 (Z-4) clad material using N 2 O as a reactive gas by RF reactive magnetron sputtering at room temperature. The Z-4 substrate was located in plasma or out of plasma during the ZrO 2 deposition process to investigate mechanical and corrosive properties for the plasma immersion. Tetragonal and monoclinic phases were existed in ZrO 2 thin film immersed in plasma. We observed that a grain size of the ZrO 2 thin film immersed in plasma state is larger than that of the ZrO 2 thin film out of plasma state. In addition, the corrosive property of the ZrO 2 thin films in the plasma was characterized using the weight gains of Z-4 after the corrosion test. Compared with the ZrO 2 thin film immersed out of plasma, the weight gains of ZrO 2 thin film immersed in plasma were larger. These results indicate that the ZrO 2 film with the tetragonal phase in the ZrO 2 can protect the Z-4 from corrosive phenomena.

The goal of this investigation was to produce a zirconia-family black ceramics that has enhanced functionality and reliability. Color zirconia ceramics have been produced by adding pigments. Pigments cause structural defects within zirconia and result in a drop in physical properties. Using environmentally friendly rice husk, we produced a black zirconia that is free of structural defects. In optimal firing conditions for black zirconia the calcining temperatures of the molding product are changed from 400 o C to 1200 o C, and the firing temperatures are changed from 1400 o C to 1600 o C. Color of testing the specimens was analyzed using Ultraviolet (UV) spectroscopy. Scanning Electron Microscope (SEM), EDAX (EDX), and Fourier transform infrared spectroscopy (FT-IR) analyses were carried out in order to examine impregnation properties and crystal phases. Universial Test Machine (UTM) was used to measure the flexual strength as well as the compressive strength. From experimental results, it was found that in optimal firing conditions the sample was calcined from 1000 o C to 1500 o C. Commission internationalde I'Edairage (CIE) values of manufactured black zirconia color were L* = 29.73, a* = 0.23, b* = −2.68. The bending strength was 918 MPa and the compressive strength was 2676 MPa. These strength values are similar to typical strength values of zirconia, which confirms that carbon impregnation did not influence physical properties.
