In this paper, we consider the results of studies of the wear resistance of the surface of a highly filled polymer-carbon composite based on a polyimide matrix modified with α-Al2O3 ceramic corundum corundum layer. To increase the wear resistance of the composite, a layer of ceramic corundum coating based on α-Al2O3 is applied to the surface of a filled, reinforced polymidic matrix by detonation gas-thermal spraying. The coating has a high degree of adhesion to the surface of the polyimide matrix. The thickness of the corundum coating layer is 200 μm. The results of studies of the wear resistance of the surface of a highly filled polymer-carbon composite based on a polyimide matrix modified with α-Al2O3 ceramic corundum corundum layer are considered. It is shown that filling a polyimide composite with modified tungsten dioxide and applying a corundum coating significantly increases its wear resistance. The brittle-plastic fracture mechanism of the polymer composite coated with α-Al2O3 ceramic corundum coating was established, the filler was chipped, and the polymer retained plastic deformation. According to tribological studies, due to the presence of a corundum layer on the polymer surface, no signs of wear are observed.
