Project abstract

The main idea of the Project is to experimentally establish the mechanisms of influence of Al₂O₃ және SiO₂ nanoparticles during PEO on the formation of the structural and phase state and properties of oxide surface layers of Al-Si alloys. As a result of the implementation of these mechanisms in practice, it is possible to significantly improve the operational properties of oxide layers obtained by the PEO method with nanoparticles. The identification and physico-chemical description of these mechanisms are presented as a set of new knowledge that will allow us to formulate theoretical positions in the physics of metals and alloys in a new way, and predict practically important properties of the obtained oxide surface layers depending on the composition of the dispersed phase of the electrolyte suspension.

The aim of the project is to experimentally establish the main mechanisms of formation of wear- and corrosion-resistant coatings obtained by plasma-electrolytic oxidation of Al-Si alloys with the addition of Al₂O₃ және SiO₂ nanoparticles.

Expected and achieved results of the project:

Optimal PEO treatment modes will be established during the study. The patterns of the influence of PEO parameters on the structure and phase composition of the obtained oxide layers will also be established, with the identification of patterns between the physico-mechanical characteristics and phase composition, and processing modes. Optimal parameters for applying PEO coatings, electrical modes (including frequency, current density, voltage), electrolyte composition with and without Al₂O₃ және SiO₂ nanopowders, and sample immersion duration will be identified.

Based on the results obtained, this project will publish 2 (two) articles in peer-reviewed scientific journals in the scientific field of the project, indexed in the Science Citation Index Expanded of the Web of Science database and (or) having a CiteScore percentile in the Scopus database of at least 65 (fifty), as well as at least 1 (one) article. or a review in a peer-reviewed foreign or domestic publication recommended by the COC HBO.

Based on the results of the experimental studies, documents for intellectual property rights will be issued. An application will be submitted to the National Institute of Intellectual Property of the Committee on Intellectual Property Rights of the Ministry of Justice of the Republic of Kazakhstan for the grant of an innovative patent of the Republic of Kazakhstan for an invention or utility model.
