Production of antifriction composite filler rods based on babbit B83 by extrusion

The manufacturing technology of the composite filler rods based on babbit B83 by extrusion is developed. The filler rods have a uniform distribution of the high-strength reinforcing particles (silicon carbide) and the modified rock shungite. It is shown that the hardness and density values of the composite filler rods correspond to the properties of cast babbit B83 alloy, but their wear resistance is superior by a factor of two.
