Study of the Dependence of the Friction Force and Coefficient of the Abrasive in the Metal Contact Zone on Various Factors

In the article, the interaction of the coefficient of friction for friction pairs operating under conditions of abrasive wear is considered, depending on a number of factors. Thus, the friction coefficient is one of the main indicators characterizing the performance of friction nodes. Analytical expressions obtained based on the calculation of the results of the conducted tests using mathematical statistical and mathematical methods allow to determine the coefficient of friction and allow the designer to effectively choose the material and oils before designing.
