    Opis:
    Free electron laser FELs are built in Europe mainly as nondependent infrastructures, or as a development of synchrotron ones. They are constructed mainly in centres which have considerable experience with synchrotron light sources of the third generation like DESY, Trieste, INFN, etc. Advances in very energetically efficient superconducting linear accelerators for electron beams, like TESLA type, caused an abrupt development of FEL machines all over Europe. New generation of FELs emits light beam of extreme intensity, good parameters, in IR, VIS, UV, EUV and X-ray spectral regions. The machine construction teams comprise also of young active researchers from Poland. In particular, these is a considerable participation of M.Sc. and Ph.D. students from Warsaw University of Technology at building of FLASH I, FLASH II, and EXFEL machines. Unique experiences gathered at work with these large experiments result in development of these young teams, and their further engagement in new initiatives: laser, laser - accelerator, inertial, plasma, plasma - energy, etc. This is what we observe with satisfaction. However, due to the lack of large research infrastructures in Poland, we are not members of the infrastructure owner clubs. Our young researchers may take part in the initiatives only indirectly as members of cooperative teams from the leading countries. As a further consequence, there is also a confined access of Polish laser and accelerator researchers to some kinds of European infrastructure development projects now under realization within the H2020.

    Opis:
    Light plays a key role in human’s life. Without light there will be no human life environment. Technologies based on light, called photonics, decide of the development of our civilization. The role of photonics is constantly increasing, especially in such fields as energy, education, agriculture and health. The UN has established the International Year of Light and Light - based Technologies – IYL2015 [1]. The organizers of IYL2015 events are professional organizations, communities, educational organizations, non-profit ones, technological clusters and platforms, but also private sector. The aim is to increase the social consciousness about the role of light and photonics in building of our civilization. This sort of recognition is necessary as a needed component of the development process of the society. Introduction of new technologies, like completely new kind of lighting, new diagnostic and therapeutic methods, new sources of energy, etc., must meet with social acceptance. In the opposite case, isolated development of infrastructure, will meet with obstacles. In Poland, the professional events, technical, trade fairs and outreach ones, are organized in the framework of the IYL2015 by Photonics Society of Poland, Polish Physical Society, Polish Platform of Photonics Technologies, etc. The paper summarizes the issues combined with the organization of the IYL2015 globally and in Poland. Extended version of this paper was published in Polish [2]. The paper is a part of a cycle of articles devoted to analysis of global processes of photonics development. Previous papers concerned initiatives Photonics21 in Europe [3-4], NPI – National Photonics Initiative in USA [5], and development of optical sciences in Poland [6-15].

    Opis:
    Technologia napawania laserowego polega na wykorzystaniu wiązki laserowej celem precyzyjnego nałożenia warstwy materiału o podwyższonych właściwościach na podłoże. Szczególne zainteresowanie budzi ona w branży lotniczej. Odpowiednie przygotowanie procesu wiąże się z wykonaniem testów symulacyjnych z wykorzystaniem modeli przepływu dwufazowego oraz interakcji wiązki laserowej z materiałem. Następnie zostają wyznaczone ścieżki ruchu głowicy przy użyciu dedykowanych narzędzi CAD/CAM. W ramach analizy technologii napawania laserowego dla zastosowań branży lotniczej przedstawiono nakładanie powłok funkcjonalnych, będących alternatywą dla chromu elektrolitycznego. Przeanalizowano również metodę regeneracji wierzchołka łopatki turbiny silnika odrzutowego. Zaprezentowano też możliwości obróbki hybrydowej w wytwarzaniu przyrostowym tytanowych komponentów lotniczych oraz metodę monitorowania temperatury celem jakościowej kontroli procesu.
    The laser cladding technology consists of the use of laser beam for precise deposition of a material layer with enhanced properties to the substrate. Therefore it finds special interest in the aviation industry. Appropriate preparation of the process involves performing simulation tests using two-phase flow models and laser beam interaction with material. Subsequently, the laser head movement paths are determined using dedicated CAD/CAM software. In the analysis of laser cladding technology applications for the aviation industry, the deposition of functional coatings, being an alternative to electrolytic chromium, was presented. Secondly, the repair of turbine blade tip was also analyzed. Moreover the capabilities of hybrid laser cladding technology with machining for the additive manufacturing aviation components made of titanium alloys were presented, as well as the method of temperature monitoring for the purpose of qualitative process control implementation.

    Opis:
    Purpose: The paper presents the issues of designing the maintenance of materials and products in accordance with the idea of Industry 4.0. The author's views on the need for augmentation of the Industry 4.0 model were also presented, as well as the author's original concept that hybrid activities in predictive maintenance and condition-based maintenance should be preceded by designing material, maintenance & manufacturing 3MD at the stage of the product's material designing and technological designing. The 3MD approach significantly reduces the frequency of assumed actions, procedures and resources necessary to remain the condition of this product for the longest possible time, enabling it to perform the designed working functions. Examples of own advanced research on several selected, newly developed materials, used in very different areas of application, confirmed the validity of the scientific hypothesis and the relationship between the studied phenomena and structural effects and the working functions of products and their maintenance and indicated that material design is one of the most important elements guaranteeing progress production at the stage of Industry 4.0 of the industrial revolution. Design/methodology/approach: The author's considerations are based on an extensive literature study and the results of the author's previous study and empirical work. Each of the examples given required the use of a full set of research methods available to modern material engineering, including HRTEM high-resolution transmission electron microscopy. Findings: The most interesting intellectual achievements contained in the paper include presentations of the author's original concepts regarding the augmentation of the Industry 4.0 model, which has been distributed so far, which not only requires augmentation but is actually only one of the 4 elements of the technology platform of the extended holistic model of current industrial development, concerning cyber-IT production aided system. The author also presents his own concept for designing material, maintenance and manufacturing 3MD already at the stage of material and technological design of the product, eliminating many problems related to product maintenance, even before they are manufactured and put into exploitation. Detailed results of detailed structural researches of several selected avant-garde engineering materials and discussion of structural changes that accompanying their manufacturing and/or processing are also included. Originality/value: The originality of the paper is associated with the novelty of the approach to analysing maintenance problems of materials and products, taking into account the requirements of the contemporary stage of Industry 4.0 development. The value of the paper is mainly associated with the presentation of original issues referred to as findings, including the concept of augmentation of the Industry 4.0 model and the introduction and experimental confirmation of the idea by designing material, maintenance and manufacturing 3MD.
