    Abstract:
    The article is devoted to the development of the direction of work on the creation of qualitatively new innovative solutions to ensure the reliability of connections of machine elements. The recommendations are based on the analysis of studies on wear process of the fixed joints of machine elements during microdisplacements in contact under the influence of vibration at high temperatures. It is established that physical and chemical processes occurring in the area of actual contact of the joint elements are varied and the effect of temperature on tribological characteristics of frictional contact is complex, since with an increase in temperature the reduction of worn-out volume can occur as well as increase of it. To predict the resistance of the contact to fretting, it is necessary to conduct a force analysis on the contact and determine the spectral composition of vibrations affecting the friction contact.

    Парадигмы современной науки
    Abstract:
    The problem of improving the reliability and service life of friction units operating in extreme operating conditions, especially at high temperatures, is mainly solved by the use of ceramic materials. The paper analyzes the tribotechnical properties of ceramic materials based on partially stabilized zirconium dioxide and formulates proposals for the optimal selection of friction pairs based on experimental data.
