Abstract
U radu je provedeno ispitivanje otpornosti na trošenje komercijalno dobavljivog neprevučenog svrdla od brzoreznog čelika, u usporedi sa svrdlima prevučenim PVD TiN prevlakom, nitriranom površinom u plazmi te dvaju svrdla prevučenih PACVD prevlakama pri suhom bušenju aluminijeve pjene. Prevlačenje PACVD provedeno je prevlakama TiN/TiCN i TiN. Ispitivanje trošenja svrdla provedeno je bušenjem provrta u dva uzorka od aluminijeve pjene i jednom uzorku punog presjeka od legure 6082 T6. Uz konstantnu brzinu vrtnje svrdla, mjerena je temperatura, sila, posmak i dubina provrta. Svrdla su nakon bušenja analizirana svjetlosnim mikroskopom. Svrdlo prevučeno PACVD TiN/TiCN prevlakom izbušilo je najveći volumen provrta, a nešto manji izbušilo je svrdlo prevučeno PACVD TiN prevlakom na sva tri uzorka. Neprevučeno svrdlo izbušilo je najmanji volumen provrta uz veće zagrijavanje od ostalih svrdla kod bušenja aluminijeve legure punog presjeka.
Abstract (english)
In this study, an investigation of wear resistance was conducted on a commercially available uncoated high-speed steel drill bit, compared to drill bits coated with PVD TiN coating, plasma-nitrided surface, and two drill bits coated with PACVD coatings during dry drilling of aluminum foam. PACVD coating was performed with TiN/TiCN and TiN coatings. The drill wear test was conducted by drilling holes in two samples of aluminum foam and one sample of solid cross-section of 6082 T6 alloy. While maintaining a constant drill rotation speed, temperature, force, feed rate, and drilling depth were measured. The drilled drill bits were analyzed using a light microscope. The PACVD TiN/TiCN coated drill bit produced the largest hole volume, while slightly smaller hole volumes were obtained with the PACVD TiN-coated drill bit on all three samples. The uncoated drill bit drilled the smallest hole volume and experienced higher heating compared to the other drill bits when drilling the solid cross-section of the aluminum alloy.
