Abstract <p>Using the methods of mathematical planning of the experiment, the optimization of the process of applying coatings based on aluminum alloys by the centrifugal induction method was performed, which made it possible to develop a mathematical model and determine the range of values of technological modes and to establish the dependences of the minimum coefficient of friction of the coating material on the parameters of centrifugal induction surfacing aluminum alloy coatings. As the main factors influencing the value of the coefficient of friction of the coating material, the rotational speed of the part, part temperature during isothermal holding, and the time of isothermal holding were considered. Based on the results of computational and experimental modeling, it is shown that, in order to obtain the optimal coefficient of friction of the coating material based on an aluminum alloy, the parameters of the process of centrifugal induction surfacing should be as follows: part rotation frequency <i>n</i> = 1700–1800&#xa0;rpm, part temperature during isothermal holding <i>T</i> = 760–780°C, and isothermal holding time <i>t</i> = 300–360&#xa0;s.</p>
