Abstract: PMMA / PTFE optical fibers with increasing lateral emission were coated with titanium nanolayer using low-temperature plasma. We investigated how this nanolayer affected the spectrum of emission when VIS LED and UVA LED light sources were used. [..] Read more

Abstract: This paper presents the results of surface modification of polymers induced by atmospheric pressure non-isothermal plasma generated in reducing atmosphere. The technology based on diffuse coplanar surface barrier discharge (DCSBD) was used with the aim to achieve highly hydrophobic surfaces. [..] Read more

Abstract: Civil Engineering is a sector that moves within the macroscale. The use of Nanotextile requires an understanding of various phenomena on a basic level, i.e. [..] Read more

Abstract: Successive development of new difficult-to-machine materials requires the adaptation of new efficient methods of their treatment, especially in finishing machining stage, which are of great importance in manufacturing processes. One of the most common finishing treatments is grinding. [..] Read more

Abstract: Forming limit diagrams (FLD) are used to determine process limitations in sheet metal forming, i.e. as a level of formability assisting in the estimation of stamping characteristics. [..] Read more

Abstract: The paper presents the analysis of non-conformances of metal plates produced in one of Polish steelworks. Selected quality tools were used in the analysis. [..] Read more

Abstract: This article is devoted to the problem of forming of axisymmetric elements of hard-to-deform material. The first stage was the deep drawing process of metal discs. [..] Read more

Abstract: The article deals with the possibility of application of infinite-source queuing model in the organization, which provides a non-stop paid telephone information services to the public. Recently, more and more emphasis has been placed on building specialized centres that will be maximally tailored to the customer requirements. [..] Read more

Abstract: The decision of what amount of a product to produce in a specific interval may impact seriously corporate earnings. Various methods have been used to eradicate this problem. [..] Read more

Abstract: The study relates to the processing of zinc-containing wastes of metallurgical production using products of joint pyrolysis of polyethylene wastes and wood pods. The process is carried out in two stages: preparation of polyethylene waste for the operation and then the recovery process. [..] Read more

Abstract: A significant number of reinforcing components are currently available for the manufacture of aluminum matrix composites. The justified selection of reinforcement determines not only the working capacity of the created composite materials under various operating conditions, but also the fundamental possibility of obtaining the composites by liquid-phase methods. [..] Read more

Abstract: In most cases, the components (U-profiles, Ω-profiles, box-beams) are used to validate the material model generated from the measurement of individual sheet metal parameters. The validation process consists of comparing the resultant force vs displacement from the experiment to the simulation. [..] Read more

Abstract: Small punch creep test (SPC test) is an alternative and still developing method to conventional uniaxial creep test and as such can be used for obtaining information about the creep properties of steels and alloys even when only a limited amount of test material is available. SPC method has been also implemented into EN 10371 "Metallic materials – Small punch test method". [..] Read more

Abstract: Nanoparticles are widely used in industry as well as biomedicine. An interesting group are aluminium oxide nanaoparticles (alumina nanoparticles) belonging to the family of metal oxide nanoparticles, which can be prepared by various methods (the sol-gel, precipitation, micro-emulsion and hydrothermal methods). [..] Read more

Abstract: For additive production, where the material is prepared by applying thin layers, a simplified designation 3D printing has been used. During this production volatile organic compounds and ultrafine particles are emitted into the air. [..] Read more

Abstract: During High Carbon ferromanganese production, the slag formation plays an important role on the overall process. Though the slag formation starts in the prereduction zone, silica may be reduced depending on the reducing conditions. [..] Read more

Abstract: In this work, the dynamic material modelling (DMM) is employed to identify the hot working window that is suitable for hot processing of Duplex stainless steel 2205 (DSS). The Gleeble 1500 thermo-mechanical simulator was used to conduct the investigation, where several hot compression tests were conducted at a temperature range of 850 - 1050 °C and strain rates of 0.001s-1 - 5s-1. [..] Read more

Abstract: Nowadays, steelmaking companies use numerical simulations as an advanced tool to optimize process parameters, reduce defects, and enhance product quality, aligning with the rising market demand for high-quality steel ingots. For more accurate simulations, it is essential to set the correct material properties, process parameters (such as flow rate and temperatures), heat transfer coefficient, as well as the suitable geometry and corresponding discretization. [..] Read more

Abstract: The research deals with the evaluation of internal quality of zinc castings in terms of porosity. The castings were produced by high-pressure die casting from ZP0410 alloy, which is an alloy of zinc with addition of aluminium and copper. [..] Read more
