Abstract
Tema ovog završnog rada je „Utjecaj postupka naštrcavanja na mehanička i tribološka svojstva čelika za poboljšavanje 42CrMo4 (Č4732)”. Rad je podijeljen na teorijski i eksperimentalni dio. U teorijskom dijelu rada opisan je postupak toplinskog naštrcavanja, navedena je njegova podjela te prednosti i nedostaci postupka. Detaljno je opisan postupak plamenog naštrcavanja, budući da se taj postupak proveo u eksperimentalnom dijelu završnog rada. Također u eksperimentalnom dijelu rada na odabranim naštrcavanim uzorcima/prevlakama provedena su laboratorijska ispitivanja u pogledu pripreme uzoraka za ispitivanja, mjerenja kemijskog sastava, snimanja karakterističnih mikrostruktura, mjerenja tvrdoća po poprečnom presjeku uzorka te tribološka ispitivanja na odabranim prevlakama. Na temelju analize prikupljenih rezultata ispitivanja, moguće je uočiti da pri povećanju broja ciklusa, uz konstantno opterećenje, dolazi do gubitka mase prevlaka AISI431 (uzorak 1) i Metco 350NS (uzorak 2).
Abstract (english)
The theme of this final paper is “The influence of thermal spraying process on the mechanical and tribological properties of the steel for improvement 42CrMo4 (Č4732)”. The paper is divided into theoretical and experimental part. The theoretical part of the paper describes the procedure of thermal spraying process, its division and the advantages and disadvantages of the process. The flame spraying process is described in detail because this process was perfomed in the experimental part of the final paper. Also in the experimental part of the paper on selected sprayed samples/coatings, laboratory tests were perfomed regarding the preparation of samples for testing, chemical composition measurements, recording of characteristic microstructures, measurements of the hardness on the cross-section of the sample and tribological tests on selected coatings. On the basis of the analysis of the test results obtained, it is possible to notice that with the increase in the number of cycles, at constant load, comes to the mass loss of coatings AISI431 (sample 1) and Metco 350NS (sample 2).
