Abstract
Tema završnog rada bila je „Postupak toplinske obrade strojnog dijela „LF.19-PT.21“. Zadani strojni dio izrađen je od čelika pa se sukladno tome i završni rad bazira na postupcima toplinske obrade čelika. Koncepcijski, rad je podijeljen u dvije veće cjeline, teoretsku i praktičnu. Teoretska cjelina podijeljenja je u tri dijela. U prvom dijelu pojašnjava se pojam čelika, navode se njegove podijele te primjena u praksi. Drugi dio obuhvaća mikrostrukturne promjene u čeliku tijekom toplinske obrade. Navode se moguće mikrostrukture čelika, njihov kemijski sastav te svojstva. Opisane su i pretvorbe kojima one nastaju te potrebni uvjeti za njihov nastanak. Također, svaka mikrostruktura popraćena je odgovarajućom slikom. Treći dio teoretskog dijela razmatra postupke toplinske obrade čelika. Navodi njihovu svrhu te svojstva koja nastaju nakon njihove primjene, odnosno promjene koje one uzrokuju u mikrostrukturi čelika. Navedeni su i parametri koje je potrebno odrediti za provođenje pojedinog postupka, što je popraćeno matematičkim izrazima i dijagramima, koji u tome pomažu. Praktični dio zadatka bazira se na određivanju parametara toplinske obrade cementiranja. Obuhvaća određivanje kemijskog sastava čelika 16MnCrS5, definiranje parametara cementiranja te detaljno razrađivanje samog postupka cementiranja po fazama, kao i potrebne matematičke izraze i dijagrame. Također, uključuje svu potrebnu tehnološku dokumentaciju.
Abstract (english)
The topic of my undergraduate thesis was „Heat treating process of workpiece LF.19- PT.21“. The workpiece assigned is made out of steel, consequently making my thesis centered around the heat treatment of steel. This assignment is separated into two major sections, theoretical and practical. The theoretical section is further divided into three smaller parts. In the first part, the definition of steel is explained, along with its types and practical application. The second part covers steel’s microstructures along with its chemical structure, all followed by images. The last part of the theoretical section presents different types of steel's heat treatment. The parameters required for every process, along with the suitable mathematical expressions and diagrams, are mentioned as well. The practical section of this assignment is based on determining the parameters needed for the heat treatment of cementation. This section also includes the chemical composition assessment for 16MnCrS5 steel. Moreover, the crucial parameters for cementation, as well as the detailed description of the process, are also covered. This is also followed by the corresponding mathematical expressions and diagrams. All of the required technological documentation has been attached as well.
