Abstract: High alloyed materials are required by certain industrial sectors as is power, chemical and nuclear industry, etc. These materials have superior mechanical properties and are resistant to chemically aggressive environment in which it must accommodate the long term mechanical stresses at high temperatures.

Abstract: When dealing with corroded objects, it is necessary to identify the corrosion products to develop a proper treatment for this particular object. Using X-ray diffraction is still suitable to do the phase composition analysis of the material; however it does the analysis of the material in bulk. [..] Read more

Abstract: Possibilities of the use of alternative drives from the point of view of operation of an industrial enterprise are at present almost unlimited, and it will always depend on concrete conditions of the company to which measure the company will decide to use alternative fuels in its fleet. One of the main arguments for using of alternative motor fuels are ecological reasons. [..] Read more

Abstract: The article deals with the evaluation of the functional surfaces of the ball valve body, which are different from other parts of the ball valve. First is the requirement of decreased roughness of the machined surface of the catch surfaces and areas where it will be used a special sealing element, and also in dimensional tolerances and, ultimately, the position tolerances as coaxiality, parallelism and perpendicularity.. [..] Read more

Abstract: Infrared nondestructive testing is an inspection method based on an external excitation of a measured sample and a thermographic analysis of its thermal response. It often uses advanced evaluation techniques based on temperature spatial and temporal changes. [..] Read more

Abstract: The paper is devoted of verification of possibilities of evaluation of initial changing of properties and behaviour of selected polymeric isolation of cables after defined temperature loading simulated of external operational conditions and simulated temperature loading evoked by current loading. There are evaluated initial properties and behaviour of selected polymeric cable isolations and properties and behaviour after natural ageing process and controlled accelerated ageing process during higher temperature loading and different time of exposition to the higher temperature. [..] Read more

Abstract: The paper is devoted by simulation of conditions of sun radiation in correlation with real loading in operational conditions of selected polymeric materials. In the second the paper is devoted by simulation of temperature conditions of loading again in correlation with temperature loading in real operational conditions of selected polymeric materials.

Abstract: The article deals with the evaluation of chosen parameters of surface roughness on the square section samples from stainless steel 316L (1.4404), manufactured by the additive technology with using Selective Laser Melting method (SLM). As part of the experiment was measured (scanned) and compared of chosen parameters of surface roughness on plane area of the samples printed in the same process parameters with a difference of power of the laser.

Abstract: The service life of components used in the construction, mining or agricultural industry depends on several factors. Primarily lifespan is influenced by the type of wear to which the parts would be subjected (for example abrasion) and environment in which components perform their function. [..] Read more

Abstract: Fracture surfaces of X70 steel DWTT broken samples are analyzed using statistical methods and fractal concepts. Applying self-affine fracture profile construction method and the first return probability method the Hurst exponent of ductile fracture areas has been found. [..] Read more

Abstract: Research were focused to different zinc coatings quality put on iron alloys (cast iron, steel). In the paper the galvanic, hot-dip and lamellar zinc coatings were compared. [..] Read more

Abstract: Recently, research-development studies conducted for the production of organic brake pads because of the usage of asbestos in brake pads have negative effects on human health and the environment. This study aims to develop to non-asbestos high performance brake pads. [..] Read more

Abstract: In the times of market-economy, all decision making processes play the key role in managing a company or organization. The more and more complicated level of production, logistics processes and logistics supply chains and networks, the growing competition or budget restrictions are some of the factors forcing the managements of companies to conduct continuous, dynamic and rational planning. [..] Read more

Abstract: To evaluate the efficiency of transport subsystem in complex logistics structures it should be assessed in terms of quantitative and valuable assessment. The quantitative assessment of its efficiency testify such indicators as performed tonne-kilometers, the number of items handled, the actual working time of transport, the quantity of goods carried, transport costs per tonne-kilometer and per consignment, utilization of working time and transport capacities owned means of transport. [..] Read more

Abstract: Based on the collaborative management theory of green supply chain, the aim of this paper is to establish the evaluation index system of coordination effect of steel enterprise green supply chain management from two aspects of economic performance and green performance. It selects Baosteel as the research object, evaluates the collaborative management of green supply chain by means of catastrophe progression method and coupling coordination degree model, and analyses the relevant data of enterprises from 2010 to 2019 Management level and the synergistic effect of green performance development. [..] Read more

Abstract: During last decades, extracting value-added products from industrial waste materials became a crucial research area because it not only provides valuable products but also mitigates the problem with disposal of these wastes and, at the same time, it facilitates saving natural resources. Various dense media for industrial separations are based on a variety of raw materials or commercially manufactured materials, such as clay, quartz, slate, galena, magnetite or ferrosilicon. [..] Read more

Abstract: As a result of the general need for lightweight product design, multi-material systems are gaining in importance. In addition to reducing component weight, the combination of different materials in a single component allows other properties to be locally tailored to its application. [..] Read more

Abstract: Heaters are an indispensable part of gas sensing platforms. It serves to heat the sensor, which increases the sensitivity of the active layer and helps in the desorption of the detected gas. [..] Read more

Abstract: Management of the logistics system in an AUTOMOTIVE production plant involves planning processes in which methods and standards are applied, including APS, S&OP, SCM and others. Planning and scheduling for a plant in the AUTOMOTIVE industry requires consideration of information, material, capital and human resources requirements in relation to the production capacity and the availability of resources.In the article, a logistics planning process is presented according to the PL9A method. [..] Read more

Abstract: Transport efficiency is one of the fundamental goals of a transport company. Carriers can use several methods and indicators to evaluate the operation of means of transport, which create a database of data for evaluating processes and the means of transport. [..] Read more
