Development process vacuum-thermal filling of polymers with lubricating material

Under certain processing conditions, the relationship between the anodic current and the polymer material that was changed during the processing by electrophysical parameters was substantiated and determined on the basis of the equation of high-frequency heating. In the course of the review, the advantages and disadvantages of the existing oil-filling methods were determined, the goal and tasks of further research. This work determines the reasons that cause the integrity violations of the structure of polyamide materials in the process of their operation, based on the methods proposed and developed by the authors. The damage was investigated taking into account the real meteorological and climatic conditions of operation of the rolling stock of Russian Railways. Using the example of glass-filled polyamide samples, necessary and sufficient parameters for defining the strength characteristics of the investigated material were determined. Experimental relationships were obtained for determining the kinetics of the formation of fractures of polymer materials
