Microparticle composites on the basis of scrap utilizable in the field of agricultural production

Abstract

Valášek P., Brožek M. (2015): Microparticle composites on the basis of scrap utilizable in the field of agricultural production. Res. Agr. Eng., 61: 92-97.For renovation of functional surfaces of machines and devices for agricultural production it is possible to use, in addition to conventionally used methods, polymers with fillers -composites. The presence of microparticles in the polymeric matrix improves substantially the abrasive wear resistance and hardness. This contribution describes tribological properties of epoxy resin filled with chips of ferrous metals -the change of volume losses increase in dependence on the pressure increase (load) having effect on the worn surface. From the carried out experiments the considerable decrease of filled resin losses is evident compared with the resin without filler. At the same time the exponential increase of volume losses with the increased load was quantified in the course of tribological tests.
