Abstract

U radu je opisano ispitivanje otpornosti prevlaka na abrazijsko i erozijsko trošenje česticama suhog kvarcnog pijeska. Od šest ispitnih uzoraka, četiri uzorka imaju TiCN i jedan TiN prevlaku proizvedenu plazmatski potpomognutim kemijskim prevlačenjem iz parne faze (PACVD), a jedan je uzorak prevučen fizikalnim postupkom prevlačenja iz parne faze (PVD). Ispitivanje otpornosti na erozijsko trošenje provedeno je određivanjem gubitka mase nakon 15 i 30 minuta u mlazu suhog pijeska. Ispitivanje otpornosti na abrazijsko trošenje provedeno je metodom „suhi pijesk/gumeni kotač“ praćenjem gubitka mase uzoraka nakon 20, 50 i 70 okretaja.

Ispitivanja su pokazala manji gubitak mase, te manje trošenje površine kod uzorka s PVD prevlakom u odnosu na uzorke s PACVD prevlakom.

Abstract (english)

The text deals with testing coatings on abrasion and erosion wear resistance under the influence of dry quartz sand particles. Of all six samples, four of them have TiCN and one have TiN coating produced by the plazma-asisted chemical vapour deposition (PACVD), while one sample is coated with physical vapour deposition (PVD). Erosion resistance test were carried out, and the mass loss after 15, and 30 minutes of wear in the dry sand stream is determined. Abrasion wear resistance were carried out using the test method „dry sand/rubber wheel“ and tracking mass loss of each sample after 20, 50 and 70 revolutions.

Tests showed less mass loss and less wear of coating by the sample coated with PVD process than the samples coated with PACVD process.
