Testiranje PVD prevlek pri preoblikovanju v stiskalnici : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoMarzelj, VidZa slovensko orodjarno smo preizkušali različne PVD prevleke na avtomobilskem orodju v ekscentrični stiskalnici. Izdelali smo upogibni vložek, ki se mu je dodelalo šest manjših vložkov. Ti manjši ... vložki se nahajajo pri aplikaciji vleka na najbolj obremenjenem mestu. To mesto je obremenjeno zaradi viška materiala pri preoblikovancu. Pri vleku oziroma upogibu izdelka nastane guba, ki močno pritiska na vložek, kar je posledica hitre obrabe prevleke. Manjše vložke smo skonstruirali tako, da ima na mestu gube poglobitev, sprostitev, da izdelek ne pritiska preveč. Za testiranje se bo uporabilo pet različnih nanosov, eden brez. Vsak posamezen vložek je bil testiran z enakim številom ciklov. Testiralo se bo na serijski proizvodnji v stiskalnici. Po določenem številu ciklov se bo vložek zamenjal in odnesel na analizo, kjer se bo spremljala površina in obraba prevleke. Z vsakim testnim vložkom smo opravili določeno število ciklov. Rezultate smo sprva pokomentirali ločeno, glede na menjave vložkov. Na koncu smo izvedli primerjavo vseh debelin prevlek in ciklov, oziroma število izdelanih kosov. Ugotovili smo, da se pri preoblikovanju trdih oziroma pločevin z visokimi nateznimi trdnostmi, tri PVD prevleke izkazujejo dobre proti obrabne lastnosti.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [V.
