Abstract
Ovim završnim radom prikazan je utjecaj nitriranja na vlačnu čvrstoću te utjecaj poboljšanja čelika i nitriranja nakon poboljšanja. Također je napravljeno ispitivanje nakon kaljenja te su probne epruvete podrvgnute različitim temperaturama visoko temperaturnog popuštanja. Na taj način željeli smo vidjeti koliki je utjecaj nitriranja nakon poboljšanja materijala. Teoretskim djelom rada objašnjeni su termokemijski postupci nitriranja i kratkotrajno kompleksnog nitriranja te je također prikazan proces toplinske obrade poboljšanja i koje faze sadrži. Opisani su općenito čelici za poboljšanje. Početak eksperimentalnog dijela rada prikazuje plan cijelog pokusa. Objašnjeni su čelici Č.4732 i Č.4734 koje 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 nitriranja na vlačnu čvrstoću.
Abstract (english)
This final work shows the influence of feritic carbonitriding on the tensile strenght and the effect of improvement of steel and nitration after the improvement. Also, a test was carried out after hardening and test tubes were supported by various temperatures of high temperature release. In this way we wanted to to see how much the nitration effect was after the material was improved. The theoretical part of this final work describes thermochemical procedures of nitration and short-term complex nitration, and the process of thermal improvement and the phase containing it is also presented. They are generally described as steels for improvement. The beginning of the experimental section shows the plan of the entire experiment. The steels Č.4732 and Č.4734 were used for testing. These are the designs and standards of how the test tubes are made. The mechanical properties of the test tubes tested, including microhardness of Brinell method were tested. The obtained values and diagrams gave an analysis and conclusion on the effect of nitration on tensile strenght.
