WEAR OF POLYMER COMPOSITE MATERIALS IN CORROSIVE-ABRASIVE MEDIA.

We examine the friction and wear of modified polyamide-6 and ED-20 epoxy resin in assemblies operating under the action of the aggressive and abrasive media used in agricultural production. As a result of these studies it is found that the corrosive-abrasive medium consisting of mineral fertilizers has the greatest influence on the wear of the polymer composite materials. The nature of the wear of the materials is determined by the nature and content of the disperse and fibrous fillers and by the composition of the corrosive-abrasive medium. It is established that the introduction of modifying additives reduces the influence of the agressive media on the magnitude of the wear of the polymer materials.
