Polimerinių medžiagų atsparumo abrazyviniam dilimui tyrimas

Mechanical properties of polymers are reviewed and the phenomenon of the abrasive wear is analyzed in the literary part. The researches of other authors on the abrasive wear and their results are surveyed. Laboratory equipment for carrying out the abrasive wear researches is introduced. Optimal mount of laboratory simulation for modeling polymeric material wear in the abrasive environment is chosen. The testing materials‘ properties are characterized. The results of researches on polymeric materials, used in enginery, on the wear in the abrasive environment are presented. The carried out research showed that wear results of the same materials under different testing conditions (“polymer-abrasive”, “polymer-steel disc” ASTM G176-03) the dependence of wear on hardness end on the coefficient of friction differs. That is influenced by the choice of polymeric materials. The scope of the work is 62 pages: 57 pictures, 1 table, 7 appendixes are included, 25 sources of literature were referred to in this work.
