Abstract
Osnovni cilj ovog rada bio je utvrditi kako usmjerenost strukture utječe na tvrdoću i abrazijsku otpornost drva bagrema (lat. Robinia Pseudoacacia) u njegova tri karakteristična presjeka. Ispitivanje otpornosti na abrazijsko trošenje provedeno je na uređaju Taber abrader, a tvrdoća je izmjerena Brinellovom metodom. U radu je utvrđeno da usmjerenost strukture ima značajnu ulogu na ispitana svojstva. Poprečni presjek pokazao je najveću otpornost na abrazijsko trošenje i najveću vrijednost tvrdoće. Radijalni i tangencijalni presjek su tijekom svih ispitivanja pokazivali slične vrijednosti te imali značajno manju otpornost na abrazijsko trošenje i tvrdoću. Prilikom ispitivanja otpornosti na abrazijsko trošenje uočen je fenomen „kritične veličine abrazivnog zrna“. Kritična veličina abrazivnog zrna slična je kod svih ispitanih presjeka i nalazi se između 125 μm i 201 μm.
Abstract (english)
The main goal of this study was to determine how the orientation of the structure affects the hardness and abrasion resistance of black locust wood (lat. Robinia Pseudoacacia) in its three characteristic sections. The abrasion resistance test was performed on a Taber abrader, and the hardness was measured using the Brinell method. It was established that the orientation of the structure has a significant influence on tested properties. The cross section showed the highest resistance to abrasive wear and the highest hardness value. The radial and tangential sections showed similar values during all performed tests and had significantly lower abrasion wear resistance and hardness. When testing resistance to abrasive wear, the phenomenon of "critical abrasive grain size" was observed. The critical abrasive grain size was similar for all tested sections and ranges between 125 μm and 201 μm.
