    The article presenting a results about dynamics of moment and coefficient of friction change is established by experimental research of applied layers upon steel parts through vibrating gas metal arc overlaying process with increased wire electrode vibrating frequency. It was established that increasing of the vibrating frequency at rate of 150 Hz leading to significantly shorter time for interaction of both surfaces to obtain a process of established wear.

    The dynamics of wear index as well as wear resistance changing is established within experimental research of deposited lay- ers upon steel and iron parts. The summary wear index at the end of experimental research of iron parts is about 4 times bigger than the wear index established within steel parts experimental research. The relative wear resistance of deposited layers upon steel parts through vibrating gas metal arc overlaying process is about 10 times higher than layers deposited on iron parts within the same working conditions.

    The dynamics of moment and coefficient of friction change is established by experimental research of applied layers upon iron and steel parts through vibrating gas metal arc overlaying. It was established that such layers has a insignificant change of the moment of interaction within the period between 4-th and 14-th hour with rate of 5,5 to 6,5 Ncm which is a sign about transition into a period of estab- lished wear regime within shorter time.
