New materials and filaments dedicated to 3D printing were obtained using the fused deposition modeling method, and the properties of the produced materials were investigated. Polylactide was used as a polymer base for the assays because of the desired properties of the polymer, mainly biodegradability, and the matrix was refilled by the addition of metallic nanofillers, such as bronze, copper, brass,...
In the present work, an effect of plasma-forming parameters on light emission during analysis by glow discharge optical emission spectrometry of Ni–Cu model alloys is studied. To evaluate the effects of plasma-forming parameters on light emission, argon pressure was varied in the range between 600 Pa and 1000 Pa under a constant power of 20 W. Moreover, a variation of power at 20 W and 30 W under...
The development of software applications and the use of VR (Virtual Reality) techniques allow to improve the company’s financial result. The construction of models of robotic stations with robots using Virtual Robot technology allows to determine the time of the machining process. It allows its optimization through the selection of accelerations, tools, tooling strategies, and so on. Determining the...
The article presents the results of microstructural characterization of newly developed three-layer thermal barrier coating (TBC) after isothermal oxidation test. Bond coats were deposited by the overaluminizing of MCrAlY coating deposited by low-pressure plasma spraying (LPPS) process. The outer ceramic layer of yttria-stabilized zirconia was deposited by the plasma spray physical vapor deposition...
In this article, a study of nonmetallic inclusions introduced during the casting process of the aluminum–silicon alloy is presented. The samples were investigated using a scanning electron microscope to find the chemical composition and X-ray tomography to check the volumetric content of the non-metallic inclusions. The samples were made from AlSi7Mg alloy, used for car wheels, with 7% weight content...
In this article, the fundamental questions concerning the diffusion path, in particular, what is the shape of diffusion path in ternary systems and how to approximate it from the initial concentration profile, will be answered. The new rules were found which allow for determining the diffusion path from a known initial concentration of the components. This approximation will allow for designing new...
