Abstract
U radu je ispitivan utjecaj plazmatskog nitriranja na titanovoj leguri Ti6Al4V koja je poznata po svojoj širokoj primjeni u medicini, zrakoplovstvu i visokonapregnutim konstrukcijskim dijelovim u strojarstvu. Plazmatskim nitriranjem na 600 °C u trajanju 9 sati, dušik difuzijom obogaćuje površinski sloj Ti6Al4V legure. Metodom „block on ring“ ispitana je otpornost na adhezijsko trošenje neobrađenih i plazmatski nitriranih uzoraka. Analizom traga trošenja na svjetlosnom mikroskopu uočeno je vrlo malo poboljšanje otpornosti na adhezijsko trošenje uzoraka koji su plazmatski nitrirani u odnosu na neobrađene uzorke. Faktor trenja je sličnog iznosa kod obje skupine ispitinih uzoraka te iznosi 0,249 do 0,251. Metodom Vickers HV 0,05 ispitana je mikrotvrdoća rubnog sloja i jezgre. Mikrotvrdoće površinskog sloja su 380 do 389 HV 0,05. Mikrotvrdoća jezgre iznosi 311 HV 0,05. Efektivna dubina nitriranja iznosi NHD = 0,05 mm ± 0,001 mm.
Abstract (english)
This bachelor thesis questiones the impact of plasma nitriding on Ti6Al4V alloy, known for its wide application in medicine, aviation and hight-level strained construction parts in mechanical engineering. When nitriding plasma to 600 ° C for a duration of 9 hours, diffusion of nitrogen enriches the surface layer of Ti6Al4V alloy. The resistance to adhesional wear of non processed and plasma nitrited samples was tested by using "block on ring" method. Analyzing the trace of wear on a light microscope, there is minor improvement in resistance to adhesive wear samples wich are plasma nitrated in relation to the non processed sample. Friction factor is similar at both groups of tested patterns and amounts to 0.249 up to 0.251. The Vickers HV 0,05 method examines the microhardness of the boundary layer and the core. Microhardness of the surface layer is 380 up to 389 HV 0,05. Microhardness of the core is 311 HV 0,05. The effective depth of nitration is NHD = 0,05 mm ± 0,001 mm
