Anotācija It is well known that TiO₂ is one of prominent materials, which can be applied as a catalyst in hydrogen fuel production, biodegradation, environmental cleaning, etc. Every application requires precise controllability of synthesis and polymorph phase. TiO₂ can be obtained by various methods, however, each of them has some limitations in specific applications. The aim of the study is the comparison of chemical, mechanical and catalytic properties of TiO₂ layers formed by different methods for applications in medicine, chemistry and physics. The result of the investigation is the knowledge about best parameters of these TiO2 coatings on Ti, including recommendations for applications in each of the fields. In the investigation of TiO2 layers on Ti substrate formed by laser irradiation and magnetron sputtering methods were studied. The topics covered by the study are following: 1. The developed new technologies and TiO₂ coatings, obtained by these technologies within the study, are products with increased added value; 2. TiO₂ is well known photocatalyst, used in waste water purification, therefore, optimization of its catalytic properties is very important for nature and environment protection; 3. TiO₂ coatings on Ti are used in medicine because of their antibacterial properties. Testing and optimization of these properties are thus related to the public health. As a result of comparable analyze of TiO2 layer formed on Ti substrate, properties were found: the mechanical properties such as: adhesion and brittleness of the structure are the best for laser processing and antibacterial properties method, which was determined by colonization of Ps. Aeruginosa and S. Epidermidis bacteria; photocatalytic study revealed that the TiO2 layers formed by magnetron sputtering method has shown that decomposition velocity is the best using methylene blue solution.
