Abstract
U ovom radu su korišteni konstrukcijski čelici 32CrMoV12-10 i 42CrMo4, koji su modificirani s različitim prevlakama, na kojima su naknadno provedena ispitivanja. Ispitni uzorci konstrukcijskih čelika prevučeni su prevlakama kemijskog niklanja, tvrdog kromiranja i nanošenjem dvije vrste prevlaka dobivenih kemijskim prevlačenjem iz parne faze, PACVD prevlaka (TiCN i TiB). Na ispitnim uzorcima je analizirana hrapavost površina, debljina dobivenih prevlaka i adhezija nanesenih prevlaka te je odrađeno metalografsko ispitivanje. Također, ispitivana su trošenja nanesenih prevlaka. Provedena su preliminarna ispitivanja trošenja abrazijskog trošenja metodom “suhi pijesak/gumeni kotač“ i adhezijskog trošenja „prizmom po prstenom“ kako bi se utvrdio utjecaj osnovnog materijala, pripreme površine i debljine sloja prevlake na otpornost trošenju. Karakteristike nanesenih prevlaka se uvelike razlikuju pa su očekivano i rezultati ispitivanja razmjerno vrlo različiti. Dobra otpornost na abrazijsko trošenje utvrđena je kod prevlaka tvrdog kroma i PACVD prevlaka dok je dobra otpornost adhezijskog trošenja primijećena kod niklanih i kromiranih površina.
Abstract (english)
In this paper, different structural steels 32CrMoV12-10 and 42CrMo4 were used, and they have been modified with different coatings and later different tests were carried out. Test specimen steels were coated with chemical nickel plating, hard chromium plating, and by applying two types of coatings obtained by chemical vapor deposition, PACVD coatings (TiCN and TiB). Surface roughness, thickness and adhesions of the obtained coatings were analysed on the test specimens, and metallographic testing was also performed. In addition, wear tests were carried out on the coatings. Preliminary tests of abrasion wear using the method “dry sand / rubber wheel” and “block on ring” for adhesion wear were performed to determine the influence of the base material, surface preparation and coating thickness on the wear resistance. The characteristics of the applied coatings are very diverse and, as expected, the test results are relatively very different. Good abrasion resistance was determined on hard chrome coatings and PACVD coatings, while good adhesion wear resistance was observed on nickel and chrome surfaces.
