Originální abstrakt
Optical measurement techniques have been successfully used for elastohydrodynamic (EHD) lubricant films studies for several decades and have significantly helped to understand the lubrication mechanisms within highly loaded machine contacts. Nevertheless, there are still many phenomena waiting for the explanation and new experimental approaches and measurements techniques are developed. Recent studies have provided promising results as to the application of spectroscopic reflectometry to the study of EHD films. Nevertheless, some simplifications were introduced. The main aim of this study was to develop a physically correct approach that could provide the additional information about the properties of lubricant film within highly loaded contacts. The principal part of this article was devoted to the effort to develop and verify the optical design suitable for such applications. This verification was carried out within lubricated contact formed between a steel barrel and sapphire disc without any semi-reflective layer. This simplified optical arrangement has enabled to obtain the correct lubricant film data and verify the applicability of the spectroscopic reflectometry for EHD lubrication films study. It represents the first step in this application of spectroscopic reflectometry and further research in the field of the behavior of thin solid films under high contact pressures is necessary to enable thin film measurements.
Český abstrakt
Článek shrnuje výsledky experimentálního ověření aplikace spektroskopické reflektometrie na studium mazacích filmů u velmi zatěžovaných kontaktů strojních částí. Spektroskopická reflektometrie je aplikována důsledně dle fyzikálního principu využívaného pro studium tenkých vrstev v optických aplikacích. Poprvé se podařilo prokázat, že tato metoda je vhodná pro studium mazacích filmů za vyskokých tlaků.
