“…It utilizes CSI technology and can measure both transparent and non-transparent materials. [8] Due to the limited size of the sampling surface, each sample had to be scanned several times. As it is a 3D type of machine, it was necessary to make cuts on measured surfaces to obtain the required values.…”

This article seeks to compare the roughness characteristics of surfaces created through unconventional machining technologies, specifically utilizing plasma and laser. Cuts of different thicknesses of material were taken for this purpose. Furthermore, the article presents an evaluation of surfaces obtained from an impression material SILOFLEX ® , followed by the determination of similarities between these impressions and original surfaces. In this work, we mainly aimed to statistically find and determine the differences between the evaluation of surfaces in accordance with ISO 4287, ISO 4288, and ISO 25 178. Next, investigation analysis of the machined and replicated surfaces was done utilizing the contactless profilometer and the follow-up statistical evaluation of measured data from compared surface groups.

“…Joining with adhesives which are sometimes underestimated is a major complement to the traditional techniques of joining materials. Adhesive joining or bonding is applied not only where the operating conditions of a joint do not require it to have high strength but also for the joining of structural materials, such as metals, and beyond simple applications, which means the aerospace industry, for example, to produce structures which require superior strength to mass ratios [1,2].…”

This paper is a discussion of the results of tests intended to (i) estimate the effects of component mix ratios and heat curing of an adhesive joint on the tensile strength, and (ii) to determine the adhesive component mix ratio for which heat curing is insignificant to the strength of adhesive butt joints. Experimental tests were carried out at ambient temperature and elevated temperature during which adhesive butt joints were loaded with a tensile force until failure. The variables were the mix ratio of epoxy adhesive components and the application of heat holding at the adhesive curing stage. An LSTM (long short-time memory) forecast was used to determine the point corresponding to the mix ratio of adhesive components at which heat holding of the adhesive joint no longer has a positive and significant importance to the final tensile strength of the joint.

“…Wear is one of the main factors affecting the performance and lifetime of the components of various mechanisms [1]. Abrasive wear is one of the dominant and common tribological wear processes [2][3][4] leading to expensive costs for repairing worn mechanisms and replacing spare parts [1]. This wear is characterized by a reduction in the volume of the material and a change in its shape, causing a decrease in work efficiency [5].…”

Road maintenance and cleaning in winter are performed with ploughshares. Due to the fact that the layer of snow and ice that is removed from the road surface contains various hard impurities, ploughshares are exposed to high intensity abrasive wear. This article deals with the resistance to abrasive wear of originally used ploughshare materials and the materials that were designed as a suitable modification of the ploughshare to increase its service life. The chemical composition of materials used to manufacture ploughshare components is unknown. For this reason, they were analyzed with an ARL 4460 spectrometer, which was used to analyze the element content. The main part of the research was focused on the abrasion resistance test, which was performed according to the GOST 23.208-79 standard. Based on the chemical analysis, it was found that the basic body of the ploughshare was made of S355J2G3 steel, and the raking blade material was made of 37MnSi5 steel. The original material (steel S355J2G3) of the ploughshare body as a reference standard was compared to steel HARDOX 450. Furthermore, a sample made of the original material of the raking blade (steel 37MnSi5) was used as a reference standard, the properties of which were compared to the newly designed OK 84.58 and UTP 690 hardfacing materials. The parametric test method of statistical hypotheses was also used to process and evaluate the weight losses of the selected materials.
