| Abstract | In the present work, the conditions for electrophoretic deposition of yttria-stabilised zirconia (YSZ) nanopowder have been investigated. For this purpose, the mixture of acetyl acetone and ethanol with different mixing ratios was used as solvent with iodine as a dispersant. To achieve a smooth, homogeneous and crack-free coatings, the following parameters were chosen to be optimised: the mixing ratio of acetyl acetone and ethanol, voltage and duration of deposition. The obtained coatings were observed by scanning electron microscope and optical microscope. The weight of deposits was also measured in different deposition conditions to observe the effects of above-mentioned parameters on the weight and consequently the quality of green coatings. All in all, the suspensions which composed of 50 vol% acetylacetone + 50 vol% ethanol led to more uniformity and fewer cracks/pores in deposits. The other parameters were optimised as follows: deposition voltage of 40 V and deposition time of 3 min. The results of polarisation test showed an improved corrosion resistance of the magnesium alloy with the application of YSZ coating, so that the I corr value decreased from 1.16 to 0.088 mA. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
