Abstract
Osnovni cilj ovog rada je utvrditi kako usmjerenost strukture utječe na abrazijsku otpornost i tvrdoću drva subfosilnog jasena njegova tri karakteristična presjeka. Tvrdoća je izmjerena Brinellovom metodom, a otpornost na abrazijsko trošenje ispitana je na uređaju Taber abraser. Udio vlage u uzorcima pri ispitivanju iznosio je 6,81 %, a gustoća 0,674 g/cm3. Najviša tvrdoća izmjerena je u poprečnom presjeku i iznosila je 8,72 HB. Veličina abrazivnih čestica ima veliki utjecaj na intenzitet abrazijskog trošenja subfosilnog jasena. S povećanjem abrazivnih čestica raste i intenzitet trošenja. U odnosu na druge autohtone drvne vrste subfosilni jasen ima viši intenzitet abrazijskog trošenja.
Abstract (english)
The aim of this work is to determine how the orientation of the structure affects the abrasion resistance and hardness of subfossil ash wood in its three characteristic sections. The hardness was measured by the Brinell method, and the resistance to abrasive wear was tested on the Taber abraser. The proportion of moisture in the samples during testing was 6.81 %, and the density was 0.674 g/cm3. The highest hardness was measured in the cross-section and was 8.72 HB. The size of abrasive particles has a great influence on the intensity of abrasive wear of subfossil ash. With the increase in abrasive particles, the intensity of wear also increases. Compared to other autochthonous wood species, subfossil ash has a higher intensity of abrasion wear.
