The article considers the influence of the content of HB-4 amorphous alloy on the tribological properties of aromatic polyamide phenylone C-2. It was found that the introduction of a dispersed filler in the amount of 10-20 mass.% leads to a positive effect: reduction of abrasion index and roughness during friction on rigid abrasive particles of the original polymer 4,7 and 1,4 times, respectively, reaching minimum values at 20 mass.% of the filler. The improvement in properties occurs due to the fact that the particles of the hard alloy (607–809 HV) strengthen the polymer matrix; as a result, the surface of metal polymers undergoes less deformation. It was found that the effective content of filler for aromatic polyamide is 20 mass.%.
