The article concerns the application of unconventional methods for increasing the durability of kinematic joints in technical devices. It presents an operational method for forming protective layers on the frictionally interacting surfaces of kinematic joint elements. These layers possess low-friction and anti-wear properties, minimizing the adverse effects of friction, such as motion resistance and wear. It is proposed to generate these layers during the initial period of the technical device’s operation by utilizing the Garkunov phenomenon.The effectiveness of the proposed method is documented by the results of our own research presented in the article. The processes of tribological wear in lubricated kinematic machine joints under conditions of normal, stable operation proceed very slowly – so much so that they have no practical impact on durability. Tribological wear intensifies significantly under conditions where the fluid film separating the interacting surfaces is disrupted. This phenomenon occurs during every start-up and shutdown, when the interacting surfaces operate under conditions of mixed friction, or even – in extreme cases – dry friction. Preventing excessive wear mainly involves coating the frictionally interacting surfaces with protective layers. (…)
