AB Microscopy is mainly used in tribotechnical diagnostics for the analysis of the total number and morphology of the wear particles in the lubrication systems. Wear particles may accelerate wear and ultimately may cause a failure in lubricating systems. Therefore, this paper deals the tribodiagnostic problem which is focused on microscopic analysis of wear particles and additional tribodiagnostic analysis of motor oil. There was taken sample of motor oil after failure of turbocharger of combustion engine. The purpose of the paper is to compare the results of microscopic analysis for evaluation of wear particles in motor oil. These analyses are key for assessing wear of the combustion engine and for indicating of impending failure. The aim of this experiment was to assess hypothesis that scanning electron microscopy (SEM) is appropriate for tribology diagnostics of seized turbocharger of internal combustion engine.
