Abstract As a result of the conducted research, using the methods of mathematical planning of the experiment, the optimization of the process of multilayer centrifugal induction surfacing of antifriction coatings based on aluminum alloys was performed, which made it possible to develop a mathematical model and determine the optimal range of values of technological modes. The dependences of the minimum wear rate of the coating material Iq (mg/m) on the parameters of multilayer induction centrifugal surfacing of aluminum alloy coatings are established. The main factors affecting the wear rate of the coating were the heating temperature of the part T (°C), the time of the isothermal exposure t (min) and the speed of rotation of the part n (rpm). Based on the results of computational and experimental modeling, it is shown that in order to obtain the optimal wear intensity of the aluminum alloy coating material, the parameters of the multilayer centrifugal induction surfacing process should be as follows: the rotation speed of the part n = 1,750–1,875 rpm, the heating temperature of the part T = 775–800 °C, the isothermal exposure time t = 7–8 min.
Keywords optimization, mathematical planning methods, mathematical model, antifriction coatings, aluminum-based alloys, lead powder sublayer, multilayer centrifugal induction surfacing
