Abstract (Croatian)

U radu je opisan postupak PACVD (Plasma-Assisted Chemical Vapor Deposition) i mogućnosti povećanja otpornosti na abrazijsko trošenje alatnih čelika za hladni rad primjenom PACVD prevlaka TiN/TiCN i TiN/Ti-B-N. Kao podloga za PACVD prevlake primijenjeni su visokolegirani alatni čelici za hladni rad X155CrVMo12-1 (Böhler K110) i Böhler K390 MC. Opisan je cjeloviti postupak ispitivanja otpornosti na abrazijsko trošenje metodom "pijesak-gumeni kotač". Površine istrošenih uzoraka su analizirane primjenom stereomikroskopije i skenirajuće elektronske mikroskopije (SEM). Ispitivanja su pokazala četiri do pet puta višu otpornost na abrazijsko trošenje svih ispitanih PACVD slojeva u odnosu na neprevučene uzorke.

Abstract

In this work PACVD (Plasma-Assisted Chemical Vapor Deposition) procedure is described, as well as the possibilities of improving resistance to abrasive wear of cold work steels by application of PACVD coatings TiN/TiCN and TiN/Ti-B-N. As the base for PACVD coatings, high-alloyed tool steels for cold work X155CrVMo12-1 (Böhler K110) and Böhler K390 MC are applied. The entire procedure of examining resistance to abrasive wear via "sand-rubber wheel" method are described as well. The surfaces of worn samples are analyzed using a stereo microscope and a scanning electron microscope (SEM). Tests showed four to five times higher resistance to abrasive wear of all tested PACVD layers in relation to non-coated samples.
