Design, Control and in Situ Visualization of Gas Nitriding Processes

The article presents a complex system of design, in situ visualization and control of the commonly used surface treatment process: the gas nitriding process. In the computer design conception, analytical mathematical models and artificial intelligence methods were used. As a result, possibilities were obtained of the poly-optimization and poly-parametric simulations of the course of the process combined with a visualization of the value changes of the process parameters in the function of time, as well as possibilities to predict the properties of nitrided layers. For in situ visualization of the growth of the nitrided layer, computer procedures were developed which make use of the results of the correlations of direct and differential voltage and time runs of the process result sensor (magnetic sensor), with the proper layer growth stage. Computer procedures make it possible to combine, in the duration of the process, the registered voltage and time runs with the models of the process

IDEE I ZAŁOŻENIA KONWENCJI O OCHRONIE DZIEDZICTWA KULTURALNEGO I NATURALNEGO I ICH REALIZACJA W POLSCE Z PERSPEKTYWY POLSKIEGO KOMITETU DO SPRAW UNESCO

Over the years, the implementation of the Convention in Poland has revealed a number of issues related to protection of heritage in line with the patterns worked out at the UNESCO forum, and resulting from the incomplete adaptation of our legal system for the protection of historic monuments and sites, insufficient public awareness and the difficulty of incorporating historical sites into modern economic development strategies. The Polish UNESCO Committee addressed the above issues with a series of papers accompanying conferences participated in by a wide range of experts, decision-makers and local government activists at various levels. Observations concerning the application of the 1972 Convention, in particular with regard to legal protection of the world heritage sites in Poland, and the need to implement the 2003 Convention for the Safeguarding of Intangible Cultural Heritage, and the 2011 UNESCO Recommendations on the Historical Urban Landscape, have convinced the Committee to review Polish legislation in terms of protection of heritage from the perspective of the UNESCO normative acts ratified by Poland. In 2014, we published a study on “Why and how to protect the cultural heritage ina modern way,” edited by the then-Chairman of the Polish UNESCO Committee, profesor Andrzej Rottermund. The paper presented a wide range of conditions for application of the existing legal provisions and expected changes, provided by various institutions and experts in the field of protection of tangible and intangible heritage and respect for cultural diversity. The need to developa new comprehensive law regulating protection of cultural heritage in Poland and taking into account the provisions of the UNESCO Convention was emphasised. What is particularly grave in application of the principles of the 1972 Convention is the lack of appropriate tools for managing world heritage sites. This includes, in particular: lack of legislation that would effectively protect the borderlines of the properties being inscribed and their buffer zones, view corridors and panoramas of sites of great historical significance. The lack of proper inclusion of local communities in the heritage management processes is a significant issue, according to the message of the 2005 Faro Council of Europe Framework Convention on the Value of Cultural Heritage for Society.Article entitled “The Social Dimension of the Cultural and Natural Landscape”, issued in 2015, discusses issues concerning immediate vicinity of properties of great historical significance. It is stated that landscape is an integral entity consisting of natural elements and cultural heritage, which is understood as both tangible and intangible heritage. Consideration should be given to how notions occurring at the UNESCO forum evolved. Particular attention should be also paid to shifting from the concept of a historic monument to the concept of heritage, and the concept of historic monument protection to the concept of heritage management. It is also important to take into account the need for sustainable protection of the natural and cultural values of landscapes, both urban and rural.Over the years, the implementation of the Convention in Poland has revealed a number of issues related to protection of heritage in line with the patterns worked out at the UNESCO forum, and resulting from the incomplete adaptation of our legal system for the protection of historic monuments and sites, insufficient public awareness and the difficulty of incorporating historical sites into modern economic development strategies.

Intelligent control system for gaseous nitriding process

In the present paper, the solutions of the following research issues have been presented:• dependencies between the process parameters and the layer structure have been defined, which serve todevelop software for the control system of the process, with the view of obtaining a complex layerstructure and optimal kinetics of its creation and growth,• assumptions for the control system of the gaseous nitriding process have been developed on the basis ofa complementary cooperation of the mathematical model and the indications of the magnetic sensorregistering the nucleation and growth of the layer.These issues comprise two complementary ways towards the construction of intelligent control systems.The first one of them consists in developing innovative databases, expert systems to aid the operator indecision making regarding the choice of defined changes to the process parameters. This is connectedwith the knowledge of possibly all the factors and mechanisms which have an influence on the result ofthe process and which make it possible to design an algorithm of changes of process parameters thatcould guarantee optimal kinetics of the layer growth and its required structure. The other one additionallymakes use of specially constructed sensors, which having been placed directly in the processes react tothe growth of layers and their structure

Nitrogen Availability Of Nitriding Atmosphere In Controlled Gas Nitriding Processes

Parameters which characterize the nitriding atmosphere in the gas nitriding process of steel are: the nitriding potential KN, ammonia dissociation rate α and nitrogen availability mN2. The article discusses the possibilities of utilization of the nitriding atmosphere’s nitrogen availability in the design of gas nitriding processes of alloyed steels in atmospheres derived from raw ammonia, raw ammonia diluted with pre-dissociated ammonia, with nitrogen, as well as with both nitrogen and pre-dissociated ammonia. The nitriding processes were accomplished in four series. The parameters selected in the particular processes were: process temperature (T), time (t), value of nitriding potential (KN), corresponding to known dissociation rate of the ammonia which dissociates during the nitriding process (α). Variable parameters were: nitrogen availability (mN2), composition of the ingoing atmosphere and flow rate of the ingoing atmosphere (FIn).Parametrami charakteryzującymi atmosferę azotującą w procesie azotowania gazowego stali są: potencjał azotowy KN, stopień dysocjacji amoniaku α oraz rozporządzalność azotu mN2. W artykule omówiono możliwości wykorzystania rozporządzalności azotu atmosfery azotującej w projektowaniu procesów azotowania gazowego stali stopowych w atmosferach azotujących uzyskanych z amoniaku, z amoniaku rozcieńczonego zdysocjowanym amoniakiem, azotem oraz azotem i zdysocjowanym amoniakiem. Procesy azotowania wykonano w czterech seriach. Parametrami ustalonymi w poszczególnych seriach była temperatura procesu (T), czas (t), wartość potencjału azotowego (KN), któremu odpowiada określona wartość stopnia dysocjacji amoniaku zdysocjowanego podczas procesu azotowania (α). Parametrami zmiennymi była rozporządzalność azotu (mN2), skład atmosfery wlotowej i natężenie przepływu atmosfery azotującej wlotowej (Fw)
