The thesis describes the development of methodology for in-situ observation of a wear process. The main goal is to correlate the friction coefficient development with the video record. It is approached by designing the external device that counts the cycles and determines the period based on infrared reflectance sensor. Another problem solved is the evaluation of the possibility of using the external probe for the in-situ Raman spectra measurement. The proposed interpretation technique is used for the deviation measurement at different rotational velocities. The techniques are demonstrated on the steel samples and DLC samples.
