Characterisation of biocompatible layers of ZrO28%Y2O used in combination with other ceramics to modify the surface of implants / Karakterizacija biokompatibilnih slojeva ZrO28%Y2O3 koji se koriste u kombinaciji sa drugom keramikom za modifikaciju površine implantata
(Inženjersko društvo za koroziju, 2021)
The aim of this study was to deposit multi-functional ZrO28%Y2O3 coating layers using the plasma spray technology and then to characterise such layers. In combination with other biomedical ceramics, this coating is intended ...
Synthesis of silver doped hydroxyapatite nanospheres using Ouzo effect
(Processing and Application of Ceramics, 2016)
Nanoemulsion technique, based on Ouzo effect, was applied for synthesis of the pure and silver doped (2.5 and 5 mol%) calcium hydroxyapatite (HAp). After calcination at 500 degrees C fully crystallized powders were obtained. ...
Study of abnormal grain growth in cold-rolled AA5182 Al-Mg alloy
(Belgrade : Institute of Technical Sciences of SASA, 2023)
Studies of recrystallization and grain growth phenomena have a long history, but the causes of abnormal grain growth (AGG) are not well understood. We report on the results of the study of the occurrence of AGG in Al-Mg ...
