[PDF] format, 0.63 Mb
The course presents a description of two-years educational master program with advanced lectures and practical training related to Nanofilms and Multicomponent Nanostructured Coatings. The program is dedicated to the first year graduate students (master's course) who specialize in the field of Materials Science and Advanced Technologies of Surface Engineering.
The course consists of a number of lectures about fundamentals and most recent developments in the fields of plasma physics and surface engineering. The educational master program describes the advanced methods of surface modification and deposition of nanofilms and multicomponent nanostructured coatings, the investigation methods of their structure (elemental and phase composition, grain size, texture, morphology, surface topography, structure of the grain boundaries, dislocation structure, etc.) and properties (hardness, Young's modulus, elastic recovery, friction and wear, impact resistance, electrochemical characteristics) as well as novel characterization technique and standards.
The lectures are accompanied by a large number of seminars which will help the students to obtain the necessary competencies. In addition, practical training in various fields is organized using advanced equipment available at the Scientific-Educational Center of SHS and the Test Laboratory of Functional Surfaces to help students to improve their knowledge and competence in the field of Nanofilms.
Important part of the course is that every student is involved in the real experimental and theoretical research under supervision of senior staff by individual working plan. This work includes the preparation of literature overview, preparation of experimental samples, their characterization and testing, preparation of the final report and oral presentation of the results at the laboratory seminar.
To conclude that the experimental/theoretical master work is successful it is obligatory to publish the results obtained at least in one review journal (international or from the list of Highest Attestation Commission of RF) and present it at one seminar or conference for young scientists.
The goal of the course is to provide a basic knowledge and practical training on nanofilms and multicomponent nanostructured coatings to train high-educational personnel for work at the research laboratories and industrial sector to solve various problems in the filed of surface engineering and development new technological processes and advanced materials.
The course provides students the following competence:
to get fundamental knowledge, competence and practical skilling in the methods of surface modification and nanostructured coatings deposition;
- to get fundamental knowledge, competence and practical skilling in the methods of coatings characterization and testing;
- to be familiar with practical aspects of novel nanomechanical characterization technique and standards;
- to solve the theoretical and applied problems connected with the development of advanced nanostructured thin films and coatings for mechanical engineering and medicine;
- to treat the experimental results using equipment software and computer programs;
- to work independently with the literature in search of the necessary information
The course assumes that the student has a background in physics, chemistry, and materials science as well as has some basic mathematical skills on the bachelor level.
