Abstract
Tvrdoća materijala je jedno od najispitivanijih mehaničkih svojstava materijala, a može se ispitati pomoću raznih metoda (Brinell, Vickers, Rockwell i dr.). U teorijskom dijelu rada opisan je pojam tvrdoće, pojedine metode mjerenja tvrdoće te posebno Rockwell metoda. Važno je naglasiti da se postupak mjerenja te umjeravanje tvrdomjera po Rockwell metodi izvodi po strogo definiranoj normi HRN EN ISO 6508:2015 kako bi se održala sljedivost mjerenja tvrdoće i točnost podataka. U eksperimentalnom dijelu rada provedena je provjera sila opterećenja na tvrdomjeru po metodi Rockwell s različitim sustavima opterećenja. Provjera sustava za opterećivanje je od velike važnosti kako bi se tijekom ispitivanja tvrdoće osigurale točno definirane sile predopterećenja i glavnog opterećenja.
Abstract (english)
Material hardness is one of the most tested mechanical properties of materials and it can be tested using various methods (Brinell, Vickers, Rockwell, etc.). The theoretical part of the paper describes the concept of hardness, certain methods of hardness measurement and especially the Rockwell method. It is important to emphasize that the measurement procedure and the calibration of the hardness tester according to the Rockwell method are performed according to the strictly defined standard HRN EN ISO 6508:2015 in order to maintain the traceability of the hardness measurement and the accuracy of the data. In the experimental part of the work, the load forces were checked on hardness tester according to the Rockwell method with different load systems. Verification of the loading system is of great importance to ensure precisely defined preload and main load forces during hardness testing.
