INFLUENCE OF BORONIZING TEMPERATURE ON THICKNESS OF BORIDE LAYERS OBTAINED ON C15 STEEL

Zadatak ovog završnog radaje ispitati i eksperimentalno prikazati utjecaj temperature boriranja na debljinu boridnog sloja koji se postiže na čeliku C15. U prvom dijelu objašnjena je podjela površinskih postupaka, te su ukratko opisani najčešći postupci. U nastavku jeopisan postupak boriranja u različitim sredstvima. Navedena su svojstva i primjena boriranih slojeva. Budući daje tema rada boriranje čelika C15, detaljnije je opisano boriranje nelegiranih čelika. U eksperimentalnom dijelu rada provedeno je boriranje čelika C15 na temperaturama 870 °C, 920 °C i 970°C u trajanju od 8 h. Snimljene su mikrostrukture i izmjene prosječne debljine nastalih slojeva. Analiza je pokazala da su na svim temperaturama nastali izrazito nazubljeni borirani slojevi.The task of this final paper is to examine and experimentally demonstrate the effect of temperature on boronizing thick boride layer that is achieved on C15 steel. First part of explication is about division of surface processes and the most common procedures are briefly described. Next is a description of the procedure of boronizing in various resources. The properties and application of coated layers are also listed. Since the theme of work is C15 steel, boronizing, boronizing of non-alloy steel.it is minutely described. In the experimental part, C15 steel was boride at 870 ° C, 920 ° C and 970 ° C for 8 h. There were recorded microstructures and changes in the average thickness of the formed layers. The analysis showed that at extremely high temperatures the extremely sawtooth boride layers were formed
