COMPOSITE BASED ON HARD-CAST IRONS UTILIZED ON FUNCTIONAL PART S OF TOO LS IN AGROCOMPLEX

The paper describes a two-body abrasion of a polymeric reactoplastic composite filled with microparticles of cast irons which is wear-resistant and suitable for an easy renovation of functional areas of machines and equipments used in agricultural production and elsewhere. The wear process is described by means of two abrasive cloths with bound abrasive grains of different grain sizes. A temperature on an interface of worn material was measured as one of factors influencing the wear process. The polymeric composites with microparticles are suitable for increasing the wear resistance. This presumption was also certified from the carried out experiment when it came to considerable decrease of volume losses of filled materials. Filling the reactoplastics-epoxy resins with cast iron chips got from the process of the material surface treatment by working is one of possibilities of their effective usage.
