ON THE QUESTION OF OPTIMIZATION OF THE PROCESS OF MULTILAYER CENTRIFUGAL PROCESSING OF ANTIFRICTION COATINGS
The paper presents the optimization of the process of multilayer centrifugal induction surfacing of antifriction coatings from aluminum alloys using the methods of mathematical planning of the experiment. This made it possible to develop a mathematical model of the process and to determine the optimal range of values of technological modes, the dependences of the minimum intensity of wear of the coating material on the parameters of multilayer centrifugal surfacing of coatings were also established. So as the main factors influencing the value of the intensity of wear of the coating, the following were determined - the heating temperature of the part, the time of iso-thermal exposure, the rotation frequency of the part. Based on the results of computational and experimental modeling, the ranges of values of the parameters of the process of multilayer centrifugal surfacing were determined to obtain the optimal wear rate of the coating material based on the aluminum alloy
