چکیده انگلیسی

The method to increase the wearing capacity of the surface layer of construction machinery transmission parts is proposed. The method is based on the use of laser processing with rational modes. The optimal parameters of processing modes, depending on the type of coating are determined. The features of the surface layer hardening after laser processing are considered. The results of studies in laser processing, which allow achieving increased reliability of transmission construction machinery, high wearing capacity, corrosion resistance, fatigue strength and necessary structure of the surface layer are presented. The results showed that in the lower layers, heated to lower temperatures, the ferrite transformation is not complete and a little austenite is saturated with carbon. The features of the application researched and the optimal value of hardness and microstructure characteristics of the surface layer after laser processing are determined. The most rational modes of laser processing, which allow achieving the improvement of tribological characteristics of the transmission mechanism parts surfaces, that contributes towards increase their wearing capacity and durability are obtained.
