Abstract

U teorijskom dijelu rada opisan je postupak boriranja u različitim medijima i njegova primjena. Opisan je nastanak i rast boridnog sloja, njegova svojstva te faktori koji utječu na njih. Nadalje, dan je uvid u postupke ispitivanja hrapavosti površine, tvrdoće metodom Vickers te otpornosti na mikroabrazijsko trošenje. U eksperimentalnom dijelu rada navedena je provedba boriranja i priprema otopine za izlaganje uzoraka koroziji. Provedeno je ispitivanje i analiza hrapavosti, tvrdoće boridnog sloja te otpornosti boriranog C45 čelika za različita vremena boriranja. Uspoređena su ispitana svojstva uzoraka prije i nakon njihovog izlaganja koroziji.

Abstract (english)

In the theoretical part of the paper, the boriding process in different media and its application are described. The formation and growth of the boride layer, its properties, and the factors influencing them are explained. Furthermore, an overview of surface roughness testing procedures, Vickers hardness testing, and resistance to micro-abrasive wear is provided. In the experimental part of the paper, the boriding process and the preparation of the solution for exposing samples to corrosion are presented. The examination and analysis of roughness, hardness of the boride layer, and the resistance of borided C45 steel for different boriding times were conducted. The tested properties of the samples before and after exposure to corrosion were compared.
