Abstract

Developing a technology that increases the service life of valve seats in CNG/LNG-powered vehicles requires the appropriate selection of material and its application technology. Commercially used valve seat materials show accelerated wear under operating conditions, especially in natural gas vehicle engines. The authors developed a new material and technological concept to protect the valve seat in CNG/LNG-powered vehicles. Two materials were used in the research: Stellite 6 alloy and Fe$_{3}$Al intermetal. A commonly used material for valve seats of combustion engines is Stellite 6. The Fe$_{3}$Al is the new proposed material coating for the protection of the valve seats of internal combustion engines. The article compares the abrasive wear resistance of these materials. The abrasion tests were performed on a T-11 pin-on-disc tester, and the counter-sample was steel S235JR. The test conditions were similar to those prevailing during the operation of the valves in the head of the internal combustion engine, without the influence of temperature. The results indicate that the Fe3Al intermetallic compound is characterised by a lower coefficient of friction and wear intensity than Stellite 6. The results of exploitation tests confirm that the Fe$_{3}$Al phase is a prospective material to be used as a protective material on the valve seat of vehicles. The authors made a mathematical model for the wear of the newly created surface layers and proposed hypotheses regarding the wear mechanisms of these layers.

用于阀门表面保护的Fe $$_{{3}}$$ Al和钨铬钴合金6涂层的耐磨性

要开发一种能延长 CNG/LNG 动力汽车气门座使用寿命的技术，就必须选择适当的材料及其应用技术。商用气门座圈材料在工作条件下会加速磨损，尤其是在天然气汽车发动机中。作者开发了一种新材料和技术概念，用于保护 CNG/LNG 动力汽车的气门座。研究中使用了两种材料：Stellite 6 合金和 Fe$_{3}$Al 金属间化合物。内燃机气门座常用的材料是Stellite 6。Fe$_{3}$Al 是一种新的涂层材料，用于保护内燃机气门座。文章比较了这些材料的耐磨性。磨损试验是在 T-11 针盘试验机上进行的，对样是 S235JR 钢。测试条件与内燃机缸盖气门工作时的条件相似，不受温度影响。结果表明，Fe3Al 金属间化合物的摩擦系数和磨损强度低于 Stellite 6。开发试验的结果证实，Fe/(_{3}/)Al 相是一种有望用作汽车气门座保护材料的材料。作者为新生成的表面层的磨损建立了数学模型，并就这些表面层的磨损机制提出了假设。

期刊介绍： This interdisciplinary journal provides a forum for presenting new ideas in continuum and quasi-continuum modeling of systems with a large number of degrees of freedom and sufficient complexity to require thermodynamic closure. Major emphasis is placed on papers attempting to bridge the gap between discrete and continuum approaches as well as micro- and macro-scales, by means of homogenization, statistical averaging and other mathematical tools aimed at the judicial elimination of small time and length scales. The journal is particularly interested in contributions focusing on a simultaneous description of complex systems at several disparate scales. Papers presenting and explaining new experimental findings are highly encouraged. The journal welcomes numerical studies aimed at understanding the physical nature of the phenomena. Potential subjects range from boiling and turbulence to plasticity and earthquakes. Studies of fluids and solids with nonlinear and non-local interactions, multiple fields and multi-scale responses, nontrivial dissipative properties and complex dynamics are expected to have a strong presence in the pages of the journal. An incomplete list of featured topics includes: active solids and liquids, nano-scale effects and molecular structure of materials, singularities in fluid and solid mechanics, polymers, elastomers and liquid crystals, rheology, cavitation and fracture, hysteresis and friction, mechanics of solid and liquid phase transformations, composite, porous and granular media, scaling in statics and dynamics, large scale processes and geomechanics, stochastic aspects of mechanics. The journal would also like to attract papers addressing the very foundations of thermodynamics and kinetics of continuum processes. Of special interest are contributions to the emerging areas of biophysics and biomechanics of cells, bones and tissues leading to new continuum and thermodynamical models.
