Abstract
Cilj je ovoga rada istražiti kako veličina abrazivnih čestica utječe na intenzitet abrazijskoga trošenja aluminijske legure AA 2024-T351 i tehnički čistoga aluminija. Rad se sastoji od teorijskoga i eksperimentalnoga dijela. U teorijskom dijelu opisano je trošenje, mehanizmi trošenja, abrazijsko trošenje, utjecajni čimbenici pri abrazijskom trošenju i fenomen kritične veličine abrazivnoga zrna. Tijekom eksperimentalnoga istraživanja utvrđeno je da veličina abrazivnih čestica ima veliki utjecaj na intenzitet trošenja ispitivanih materijala. Intenzitet trošenja tehnički čistoga aluminija viši je od Al-legure AA 2024-T351. Kod oba materijala izražena je kritična veličina abrazivnoga zrna. Zbog različite mikrostrukture i svojstava Al-legura ima višu vrijednost kritične veličine abrazivnoga zrna (≈ 125 μm) nego tehnički čisti aluminij (≈ 82 μm). Također je utvrđeno da veličina trošene površine uzoraka utječe na intenzitet trošenja i ne smije se zanemariti pri iskazivanju rezultata.
Abstract (english)
The purpose of this paper is to determine the infuence of abrasive size on wear rate of Al-alloy AA 2024-T351 and technically pure aluminum. The paper is comprised of a theoretical and an experimental part. Wear, wear mechanisms, abrasive wear, influential abrasive wear factors and the phenomenon of critical abrasive size are explained in the theoretical part. During the experimental part it was determined that the abrasive size has a great influence on abrasive wear. Wear rate of technically pure aluminum is higher than the wear rate of Al-alloy AA 2024-T351. Critical particle size is noticeable for both materials. Due to different microstructures and properties, Al-alloy has a higher value of critical abrasive size (≈ 125 μm) than technically pure aluminum (≈ 82 μm). It was also determined that the size of the sample's worn surface affects the wear rate and can not be overlooked when results are reported.
