RESEARCH OF THE POSSIBILITY APPLICATION OF THERMAL SPRAYED LAYERS CONSIDERING TO THE SPECIFIC PROPERTIES

Tema ovog završnog rada je „Istraživanje mogućnosti primjene naštrcanih slojeva s obzirom na specifična svojstva”. Rad je podijeljen na teorijski i eksperimentalni dio. U teorijskom dijelu rada opisani su najvažniji postupci toplinskog naštrcavanja te prednosti i nedostaci pojedinih postupaka. U eksperimentalnom dijelu rada na odabranim uzorcima provedena su laboratorijska ispitivanja u pogledu snimanja karakterističnih mikrostruktura te mjerenja tvrdoća po poprečnom presjeku uzoraka. Na temelju analize prikupljenih rezultata ispitivanja, moguće je uočiti da uzorak 2, prevučen sa prevlakom Metco 350NS, ima dosta bolje prianjanje na površinu te homogeniju strukturu u odnosu na uzorak 1 (prevlaka AISI431).The theme of this final paper is “Research of the possibility application of thermal sprayed layers considering to the specific properties“. The paper is divided into theoretical and experimental part. The theoretical part of the paper describes the most important procedures of thermal spraying process and the advantages and disadvantages of the certain procedures. In the experimental part of the paper on selected samples, laboratory tests were perfomed regarding the recording of characteristic microstructures and measurements of the hardness on the cross-section of the sample. On the basis of the analysis of the test results obtained, it is possible to notice that the sample 2 coated with the Metco 350NS coating has a much better adhesion to the surface and a homogeneous structure in regards to sample 1 (coating AISI431)
