Abstract
Ovim završnim radom prikazan je kakav utjecaj različitih temperatura visoko temperaturnog popuštanja na efektivnu dubinu nitriranja tj. ponašanje termokemijskog procesa nitriranja kod različitih vlačnih čvrstoća strojnih dijelova. Teoretskim djelom rada prikazan je proces toplinske obrade poboljšanja i koje faze sadrži. Opisani su općenito čelici za poboljšanje. Objašnjeni su i termokemijski postupci klasičnog nitriranja i ionitriranja. Početak eksperimentalnog dijela rada prikazuje plan cijelog pokusa. Objašnjen je čelik Č.4732 kojeg smo koristili za ispitivanje. Navedeni su nacrti i standardi kako su testne epruvete izrađene. Ispitana su mehanička svojstva testnih epruveta, uključujući mikrotvrdoću Vickers metodom. Dobivenim vrijednostima i dijagramima dana je analiza i zaključak o utjecaju procesa poboljšanja na efektivnu dubinu nitriranja.
Abstract (english)
This final work shows the influence of different temperatures of high temperature relieving on the effective depth of nitration, ie the behavior of the thermochemical process of nitration at different tensile strength of the machine parts. The theoretical part of the paper presents the process of heat treatment and which phases it contains. Steels for tempering are described generally. Thermochemical methods of classical nitration and iontraction are also discussed. The beginning of the experimental part shows the plan of the whole experiment. The steel Č.4732 was used for the test. The designs and standards of how the tensile specimens are made were also described in the work. The mechanical properties of the test tubes, including the microhardness with Vickers method, were tested. The obtained values and diagrams gave an analysis and conclusion on the effect of the improvement process on the effective nitration depth.
