Abstract
U ovom radu detaljno je opisan postupak cementiranja čelika te njegova primjena. Cementiranje je postupak toplinske obrade koji se sastoji iz pougljičavanja i kaljenja nakon čega slijedi niskotemperaturno popuštanje. Čelici koji su pogodni za cementiranje sadrže do 0,25 % ugljika. Iz tog razloga im se prvo površinski sloj dodatno obogaćuje ugljikom nakon čega se kali kako bi dobio željena svojstva kao što su otpornost na trošenje i udarna opterećenja te samim time veća izdržljivost. Svoju primjenu čelici za cementiranje pronalaze kod izrad osovina, vratila, zupčanika i sličnih strojnih dijelova kod kojih su navedena svojstva izrazito bitna. Tvrdoća i dubina cementiranog sloja može se ispitati različitim metodama od kojih se najviše primjenjuju Knoopova i Vickersova. Na temelju dobivenih vrijednosti postupak se može usporediti s ostalim postupcima toplinske obrade koji se primjenjuju u sličnim uvjetima poput indukcijskog kaljenja, nitriranja ili karbonitriranja.
Abstract (english)
In this paper the procedure for cementation of steel and its application is described in detail. Cementation is a heat treatment process consisting of carburizing and case hardening followed by a low temperature release. Concentrated steel contains up to 0,25 %C. For this reason the first surface layer is additionally enriched with carbon after which it is necessary to use case hardening to obtain the desired properties such as wear resistance, impact loads and therefore greater durability. Cementation found its application in the manufacture of shafts, spindles, gears and similar machine parts where these properties are extremely important. Hardness and depth of the cemented layer can be examined by various methods, most of which are Knoop and Vickers. Based on the obtained values, the process can be compared with other heat treatment processes that are applied under similar conditions such as induction hardening or nitration.
