Overview of the 18th International Scientific and Technical Conference Rapid Solidification Materials and Coatings A A Lozovan1 and D K Kostrin2 1Department of Materials and Materials Technology, Moscow Aviation Institute(National Research University) “MAI”, 121552, Orshanskaya, 3, Moscow, Russia 2Department of Electronic Instruments and Devices, Saint Petersburg Electrotechnical University “LETI”, 197376, Professora Popova, 5, Saint Petersburg, RussiaE-mail: alexandr.lozovan@yandex.ru . In this preface the main results of the 18th International Scientific and Technical Conference Rapid Solidification Materials and Coatings that was held on 19–20 October 2021 in Moscow, Russia are discussed.From 19 to 20 October 2021, the 18th International Scientific and Technical Conference Rapid Solidification Materials and Coatings (RSMC–2021) was held at the Moscow Aviation Institute (National Research University).Despite the difficulties associated with the coronavirus pandemic, more than 100 specialists from leading universities, the Russian Academy of Sciences and Russian enterprises, as well as scientists from Ukraine and Belarus, took part in the Conference. For the successful holding of the Conference in a pandemic, all the necessary measures were taken to ensure the implementation of sanitary rules and standards for the protection of Conference participants.At the Conference the results, which were obtained in the last year after the previous Conference, of the theoretical and experimental studies on the physics of condensed matter, low-temperature plasma physics, electronic and ion-plasma surface modification, physical methods of film deposition and other studies obtained over the last year after the previous Conference.The main objects of these studies were superficiality and superficial phenomena. Therefore, to the development and improvement of methods of surface modification and coatings deposition, as well as methods of their research and development of modern surface treatment equipment was paid the greatest attention at the Conference.During the Conference more than 70 reports were presented, which were heard in the following, traditional Conference sections (figure 1):• section 1 – Rapid solidification materials;• section 2 – Methods of coating application and research;• section 3 – Laser, electron-beam and ion-plasma methods of surface modification;• section 4 – Composite materials and permanent joints;• section 5 – Works of young scientists.The Conference was opened by Alexander Vladimirovich Bespalov, Co-Chairman of the Director of the Department of Materials Science and Materials Technology of the Moscow Aviation Institute (National Research University), who emphasized the importance of developing research in the field of physical and physicochemical methods of obtaining and processing new materials and coatings for the aerospace industry. He also noted the achievements of the Institute’s scientists in the field of laser coating and fast solidification materials.List of Organizing Committee, Program Committee, Photos are available in this pdf.

September 5-8, 2017, Sumy State University, Sumy, UkrainePROCEEDINGS EDITED BYVolodymyr MARTSYNKOVSKYY, Prof., Dr., Dr.h.c., Sumy State UniversityIgor TVERDOKHLEB, Ass. prof., Dr.-Ing., HMS GROUPAndriy ZAHORULKO, Ass. prof., Dr.-Ing., Sumy State UniversitySerhii HUDKOV, Dr.-Ing., Sumy State UniversitySelected, peer reviewed papers from the XV International Scientific and Engineering Conference HERVICON+PUMPS-2017FOREWORDThe Conference Proceedings devoted to problems of reliability and economy of pump and compressor equipment are offered to the attention of specialists. The book presents 58 papers of various authors, included in the Program of the XV International Scientific and Engineering Conference HERVICON+PUMPS-2017, which, since 1976, with an enviable constancy passes every three years in Sumy on the basis of the General Mechanics and Machine Dynamics Department of the Sumy State University. The main sponsor that provided holding of the current conference, as well as the previous one, was the HMS Group, demonstrating an effective interest in the technical progress development.Published papers are grouped in five sections, which cover a wide range of issues of modern theory and practice of centrifugal machines. At the present stage of its development, the theory, thanks to the successes of computational mathematics and computer technology, is experiencing a period of prosperity. The possibility of numerical analysis of more perfect mathematical models of unsteady flows of real liquids and gases in flow channels has appeared. The existing solutions are specifying, the new physical processes laws accompanying the operation of pumps and compressors are finding. In the published papers, at least to a small extent, the present state of the theory of these machines is reflected. Part of the papers is devoted to the implementation of new design solutions. The results of experimental investigations and operational experience of the proposed designs are given (Sections 1 and 2).Centrifugal pumps and compressors - rotary machines. The most critical units of these machines are bearings and seals, which are complex tribomechanical systems. The papers given in Section 3 and 4 are devoted to the problems of calculating and designing of bearing and seals, increasing of the wear resistance of friction pairs.The unbalanced rotor of a centrifugal machine is the source of vibration disturbances, which determine the vibration state of the machine as a whole. At the same time, the level of vibration is one of the main indicators of reliability, therefore reliability problems are directly related to the rotor dynamics in the bearings and annular seals. The rotor dynamics are discussed in Section 5.On behalf of the authors’ team, I hope that the papers published in the book will awaken the interest of young research engineers and will be useful to experienced designers in creating new reliable and economical pumps and compressors. In addition, the technical personnel involved in the maintenance and repair of units, can to get useful information from the book.Professor Volodymyr A.
