The main objective of scientific research is to develop methods of structural engineering nanostructured multilayer coatings based on nitrides and carbides of transition metals with desired physical and mechanical properties. Object of study: guided technology for nanostructured multilayer coatings with a set of predicted properties based on nitrides and carbides transition metals, as well as physical and chemical processes that contribute to the formation and change of phase state, structure, substructure and functional properties of coatings. Subject of research: mechanisms and models of formation nanostructured multilayer coatings based on nitrides and carbides of transition metals with a given set of physical and mechanical properties. The purpose of the study is to develop advanced technologies for nanostructured multilayer coatings with improved tribological and physical and mechanical properties, and establishing of basic laws, the creation of models and the development of physical ideas about the processes that determine the composition, structure, functional properties of nanostructured multilayer coatings. The project objectives are to study the influence of deposition parameters, thickness and composition in bilayer to properties of coatings and technological development of recommendations for practical application of these coatings. The difficulty is to obtaining materials by vacuum arc evaporation is a multifactorial process, which should also include the impact of conditions of deposition and impurity atoms working atmosphere in the chamber to the structure, stress state, elemental and phase analysis of the growing surface. In this work the deposition of multilayer coatings MoN/CrN on steel substrate by vacuum arc evaporation deposition under different conditions was done. An initial study of the structural state and phase composition of the coating were carried out. The change in potential bias applied to the substrate from -20 to -150 V leads to various structures in the coatings from cubic (such as NaCl) to the formation of a solid solution was established.

Saving a scientific data set occurs in two stages:
1.) Creating a data set
Enter the name of the set, a brief description of the set (annotation), and click the “Create set” button. After that, a draft data set will be automatically created, which you can save for further work with the set. The system will redirect you to the “Data set information” page.
2.) Filling in the data
On the “Data set information” page, you need to fill in all the fields related to the data set and upload the files.
Please note! Each file is uploaded separately. This is done to ensure the stable operation of the system.
Once you have filled in the information about the scientific data set and added the necessary files, you can save the draft or send the data to the system.
Please note! Once the data has been sent, you cannot change it.
Drafts are necessary for storing the data set and editing it before sending.
All accounts on the NRA website go through a standard registration procedure and are verified. However, in order to obtain additional features, such as publishing open reviews of academic texts, verification by affiliation is required.
To obtain the status “verified”, you must change your primary email address to a corporate one, which is tied to a scientific or educational institution.
For example: user@ukrintei.ua, user@nas.gov.ua
After confirming your corporate email address, your account will be automatically verified by affiliation.
If your email address is corporate, but your account does not have a verification mark, you need to write to us at the email address NRAT@ukrintei.ua. After verification, we will add your address to the database, and your account will be verified.
After completing the verification procedure for affiliation, you can change the primary email address to a convenient one for you, without losing your status during the current verification.
You only need to verify for affiliation once.
* We use corporate addresses from the Unified State Database on Education and the State Register of Scientific Institutions Supported by the State
To search for news published on the official website of NRАT in the “News” section, you need to enter one word, several words, or an exact phrase in the search field. Different terms are separated by spaces.
The search is performed everywhere – in the title and the news text.
For a more comprehensive result, it is recommended to use word stems (parts of words without endings).
When using multiple words for the search, they are combined using one of the logical methods described below.
By default, the logical connector “and” is used. In this case, search results will include all news releases that contain the specified words, even if they are located separately from each other and are in different parts of the text.
Example: Search phrase: OECD report. Search result: all news containing the words “report” and “OECD” in the text and in the title, both together and separately.
If a phrase or phrase is enclosed in quotation marks (“), the results will include all publications where this exact phrase or phrase is found.
Example: Search phrase: “OECD report.” Search result: all news containing the exact phrase “OECD report.”
If you know the publication date of the news or are interested in a specific time frame in which they were published on the website, you can select such a date or date range in the additional field that looks like a calendar. The date is entered in the format year-month-day and confirmed by clicking on the corresponding date in the calendar dropdown. You can enter a date or choose one by browsing through the calendar by months and years. By default, the interval starts from the oldest date (2018-01-23) and ends with the current date.
You can also use one or more hashtags, which are located under the search field on the right side of the “News” page.
Please note: The search for academic texts is carried out in a separate search window at the following link https://nrat.ukrintei.ua/searchdb.
