Abstract
U radu je opisano djelovanje opterećenja, mehanizmi trošenja i zahtjevi na svojstva materijala za metalne klizne ležajeve. Opisane su mogućnosti toplinske obrade i prevlačenja površine kliznog ležaja od čelika DIN 100Cr6. Provedeni su postupci prevlačenja TiN prevlakom i TiN/TiCN prevlakom postupkom PACVD, te nitriranje u plazmi. Ispitana je hrapavost površine, debljina i adhezivnosti prevlaka, otpornost na adhezijsko trošenje i faktor trenja. Iz ispitivanja hrapavosti površine uočene su razlike u parametrima i profilima hrapavosti ispitnih uzoraka. Izmjerena je debljina prevlaka i određena je prianjivost prevlaka. Iz provedenih ispitivanja utvrđeno je da je kod suhog trenja i opterećenja od 98,1 N najmanje adhezijsko trošenje ostvario tribopar „neprevučeni prsten - prsten prevučen TiCN/TiN prevlakom“. Najmanji faktor trenja uz povećano trošenja utvrđeno je kod tribopara „ležajna bronca -neprevučeni prsten“ pri dodiru u točci.
Abstract (english)
The paper describes the effects of loads, wear mechanisms and requirements on the properties of the materials for metal plain bearings. It describes the possibilities of heat treatment and coating of the plain bearing surface made of DIN 100Cr6 steel. The PACVD coating procedure of TiN coating, TiN/TiCN coating and plasma nitration were performed. The surface roughness, thickness and adhesiveness of the applied coatings and the resistance to adhesive wear tested by the friction factor and the width of the wear traces were examined. Differences in surface roughness parameters and profiles were observed from the sufrace roughness test. The thicknesses of the coating were measured and the quality of adhesion of the coatings was determined. From performed tests, it was determined that at dry friction and load of 98,1 N, the lowest adhesion wear was achieved by friction pair „uncoated ring – ring coated with TiCN/TiN coating“. The lowest friction factor with increased wear was found in the friction pair „bearing bronze – uncoated ring“ when touched at a point.
