Purpose: The aim of the proposed research is to investigate hydrogen effect on high-nickel steel surface properties changing during machining and wear with participation lubricant-cooling environments. Design/methodology/approach: approach fracture mechanics physicalchemical methods investigation was used formulate conclusions. Applying (liquid, solid, gaseous) technological environments (LCTE) has change morphology chips roughness contact 23Ni1Mo3Ti surfaces depending experimentally fixed...
This article is devoted to the following issues: calculating values of temperatures obtained by simulating welding heating and subsequent implementation process at given mode parameters made it possible obtain a welded joint rotor with an improved initial structure increased mechanical properties, hydrogen resistance durability up 10–15%; in areas fusion, overheating normalization HAZ formation austenite grains; specified creates conditions for new products decomposition form sorbitol area...
Abstract The effect of hydrogen on short-term strength, low-cycle durability and planestress fracture toughness 10Cr15Ni27 steel, 04Cr16Ni56 05Cr19Ni55 alloys at pressure up to 35 MPa temperature 293. . 773 K was investigated. modes action for which the elongation , reduction area N crack resistance parameters Kc are minimal were established: above 10 (non-hydrogenated specimens alloy) 15 (hydrogenated steel alloy, concentration 19 wppm, respectively).
This article presents a theoretical analysis of the use spiral-elliptical ducts in atomizer modern fuel injector. The parameters injected stream can be divided into quantitative and qualitative. parameter is injection dose amount, qualitative characterized by (width, atomization, opening angle, range). purpose modification to cause additional flow turbulence, which may affect improve combustion process combustible mixture diesel engine. discussed here could used engines powered vegetable...

This article presents the authors’ considerations regarding possibilities of developing fuel equipment for modern compression ignition engines used in special and non-road vehicles. The paper discusses process combustion atomization chamber a piston engine. then concept modifying atomizer injector operation using hydrogen-containing fuels plant origin. authors present review tests performed an engine dynamometer on with Common Rail system running biofuel. CI operated standard modified...
The article concerns the possibility of using a fuel pretreatment system in modern compression ignition CI engines, main task which is reduction toxic emissions form exhaust gases. This consists catalytic reactor used common rail (CR), and modified atomizer into spiral‒elliptical channels covered with material. In presented here, platinum was catalyst. catalyst’s to cause dehydrogenation reaction paraffin hydrocarbons contained create an olefin form, release free hydrogen molecule....
Increasing energy efficiency in hybrid electric vehicles is associated with the possibility of recovering some kinetic delayed movement phase and converting it to electricity, which can be used charge batteries. It structurally possible implement by using an machine operating as a generator accumulation system. In addition widely lithium-ion storage systems, nickel-metal hydride solutions are also alternative. Battery systems characterized specific electrical parameters include, among...
In this study, modern nitrogen steels used for the manufacture of rings Honda engines (70CC, 90CC, CRF70F, XL70, XR70, C70, CT70, ATC70, CL70) as well other transport tribotechnical units was investigated. Due to present ecological situation in world, new environmentally friendly lubricating fluids steels’ and surface treatments have been proposed. The results tests are presented form diagrams, graphs step polynomials obtained by mathematically describing changes wear intensity when load...
It has been described the conception of using platinum catalytic layer in multi hole fuel injector atomizer. The placed on not working part atomizer needle. aim modification was activation dehydrogenation reaction paraffin to olefin hydrocarbons with escape hydrogen molecule CI engine bio fuel. and process leads presence its influence structural materials properties after catalysis which requires high crack resistance used materials. There is speed steel as material. Article describes how...
It has been established that, at some region of hydrogen pressure and strain rate exists a maximum influence on the plasticity, low cycle fatigue cyclic crack resistance Ni-Co alloys high nitrogen steels. The drop plasticity dispersion-hardening materials within temperature range intense phase transformations is caused by localization strains grain boundaries due to redistribution alloying elements in boundary regions. Moreover, increase observed higher temperatures both partial coagulation...
It is experimentally established that illumination of GaSe (Pb) hydrogen saturated layered semiconductor electrodes in acids (H 2 SeO 3 , H SO 4 ) and neutral (water) environments has improved the anode cathode reactions.The influence solution on potential open circuit current density different for crystals initial state after hydrogenation. During sunlight irradiation, polarization takes place at low values more positive value potentials comparison with result obtained darkness. Taking into...
