摘要

本出版物提出了使用金属间Al-Fe合金延长汽车涡轮增压器转子轴密封圈使用寿命的可能性。该合金(真空铸造)在T-05台架上的滑动协会中进行的摩擦学，金相学和轮廓学测试的综合结果允许表示真实的摩擦节点。根据经验测试，将有可能确定哪种合金(Al-Fe合金或目前用于汽车涡轮增压器转子轴密封圈的合金)具有更好的摩擦学性能。为此，本研究基于一项实验，该实验假设了决定被测接头磨损的三个主要因素。实验方案的结果是得到了显示磨损因素对摩擦力和表面形貌影响的三维图表。

EVALUATION OF THE WEAR OF AN FE-AL ALLOYTURBOCHARGER ROTOR SEAL RING UNDER SELECTEDOPERATING CONDITIONS

This publication presents the possibility of extending the service life of the rotor shaft seal ring in an automotiveturbocharger by using an intermetallic Al-Fe alloy. Comprehensive results of tribological, metallographic andprofilometric tests of this alloy (vacuum cast) operating in a sliding association on a T-05 bench allowedthe representation of a real friction node. Based on empirical tests, it will be possible to determine whichalloy (Al-Fe alloy or the one currently used for sealing rings of a car turbocharger rotor shaft) has bettertribological properties. For this purpose, the research was based on an experiment that assumes three mainfactors determining the wear of the tested association. The result of the experimental plan was to obtain threedimensionaldiagrams showing the influence of the wear factors on the friction force and surface topography.
