SPECIFIČNA SVOJSTVA ČELIKA NAKON NITRIRANJA

Tema ovog završnog rada je „Specifična svojstva čelika nakon nitriranja“. U završnom radu se opisuje proces nitriranja. U uvodnom djelu se upoznajemo sa toplinskom obradom te njezinom primjenom u svim granama industrije. Upoznajemo se sa samim izrazom nitriranja te njegovim značenjem. Nakon toga detaljno je opisan sam proces nitriranja te postupci nitriranja kao što su plinsko nitriranje, nitriranje u solnim kupkama i plazma nitriranje. Navedeni su čelici pogodni za nitriranje i njihova svojstva. Na kraju rada opisana su svojstva nitridnog sloja te primjena nitriranih dijelova. Provedbom nitriranja postiže se tanki nitridni sloj, svojstva tog sloja su visoka površinska tvrdoća, otpornost na trošenje, otpornost na umor, dinamička izdržljivost i postojanost pri višim temperaturama. Zbog tih svojstava nitrirani dijelovi imaju veliku primjenu u svim granama strojarstva.The topic of this final paper is „Specific properties of steel after nitriding“. The final paper describes the nitriding process. In the introductory part, we get acquainted with heat treatment and its application in all branches of industry. We get acquainted with the very term nitration and its meaning. After that, the nitriding process itself is described in detail, as well as nitriding processes such as gas nitriding, nitriding in salt baths and plasma nitriding. The listed steels are suitable for nitriding and their properties. At the end of the paper, the properties of the nitride layer and the application of nitrided parts are described. By performing nitriding, we achieve a thin nitride layer, the properties of this layer are high surface hardness, wear resistance, fatigue resistance, dynamic durability and resistance to higher temperatures. Due to these properties, nitrided parts are widely used in all branches of mechanical engineering
