Issues related to the components of modern fuel equipment wear processes have been discussed. The injector is one key elements system, because it a device responsible for distributing and spraying hydrogen-containing in engine combustion chamber. It mounted head directly If faulty, affects operating parameters particular ecological engine, such as emission toxic substances into environment. Additionally, hydrogen reactor has installed Common Rail (CR) task which produce hydrogen. As result...
PTFE/C composite targets were ablated using a pulsed electron beam of different energies to evaluate the suitability this technique for coating deposition. Composite materials with two carbon fillers and their contents (graphite—10 wt.% coal coke—35 wt.%) used. A PTFE target was used as reference material. The chemical physical structure coatings investigated FTIR, XPS, XRD. topography optical microscopy, SEM, AFM. In addition, contact angle surface energy evaluated. It shown that presence...
The demand for lightweight, strong structural profiles is currently high in the transport industry, mechanical engineering, and construction. Therefore, it important to evaluate their properties, especially properties. main objective of this paper determine energy absorption coefficients crush resistance thin-walled aluminum using numerical simulation empirical verification. This presents compression results testing filled with a porous material (cast foam). analysis was conducted software...
Nanoflex stainless steel is a promising material for medical applications. However, improvement of its mechanical properties without compromising corrosion resistance still challenge. In order to investigate the effect nitriding process on and wear Sandvik NanoflexTM steel, number processes were carried out in gas atmosphere with differing ammonia contents temperature range 425-475 °C 4 h. The layers tested using nanoindentation pin-on-disc methods, respectively. assess resistance,...
This study presents research results concerning the vacuum carburizing of four steel grades, specifically conforming to European standards 1.7243, 1.6587, 1.5920, and 1.3532. The experimental specimens exhibited variations primarily in nickel content, ranging from 0 approximately 3.8 wt. %. As a comparative reference, gas was also conducted on 1.3532 grade, which had highest content. Comprehensive structural analysis carried out resultant carburized layers using variety techniques, such as...
A proprietary slurry cementation method was used to produce silicide-aluminide coatings on alloy Ti-6Al-4V. The processes were carried out at 900–1100 °C for 2–6 h. exhibited a stratified configuration characterised by phase arrangement that demonstrates favourable attributes pertaining mechanical and corrosion resistance capabilities, namely, the presence of aluminium-enriched phases coating surface titanium-enriched proximity substrate. cyclic oxidation behaviour 800 30 twenty-two-hour...
It has been demonstrated that apart from the known compounds YbVO4 and Yb8V2O17, a substitutive solid solution is also formed in binary oxide system V2O5–Yb2O3. This characterized by limited solubility of vanadium(V) crystal lattice ytterbium oxide, its general formula Yb2−5x□2xV3xO3, where 0.00 < x 0.1667. The new was obtained mixtures V2O5 Yb2O3 oxides, containing amounts not exceeding 30 mol%, high-energy ball milling planetary mill. using methods XRD, DTA-TG, SEM, IR UV–Vis-DR. found to...

K-TIG (Keyhole Tungsten Inert Gas) method is a new, emerging welding technology that offers significant acceleration of the joining process, even for very thick plates. However, its potential certain materials still unknown. Particularly challenging are duplex steels as this does not allow use filler material, which crucial these and weld joint microstructure adjustment. In order to demonstrate suitability single-pass 1.4462 steel detailed studies joints obtained different linear energies...
This paper presents results of investigations on gas nitride layers stainless steel. Steel with ferritic structure, containing different chromium and nickel content was used in the experiments order to compare influence these two main alloying elements layer growth kinetics structure. Particular attention paid formation Sphase expanded martensite which usually are formed during lowtemperature nitriding It observed, that does not have a significant but treatment temperature does. also stated...
