ALUMINUM DIE - CASTING AND CAVITATION PHENOMENA

V diplomskem delu je predstavljen proces tlačnega litja aluminija skupaj s težavami, ki se pri tem pojavljajo. Opisane in natančneje predstavljene so vse posamezne faze livarskega procesa. Natančneje je opisan princip mazanja orodja, proces litja s poudarkom na tlačnih fazah in obrobni procesi, ki potekajo pri izdelovanju ulitkov. Opisane so lastnosti in prednosti aluminija pred konkurenčnimi materiali. Predstavljene so najpogostejše napake, ki se pojavljajo pri tlačnem litju aluminija s poudarkom na kavitacijski eroziji. Opisane so osnove kavitacijske teorije. Natančneje je opisan princip nastanka kavitacije pri tlačnem litju. Na kratko je opisana raziskava, ki je bila izvedena v zvezi s preučevanjem kavitacijske erozije, ki se je pojavljala na aluminijastem ulitku.This thesis presents aluminium die-casting along with some problems that are involved in it. All individual phases of die casting process are closely observed and introduced with special emphasis on die spraying process, individual die casting phases and all others things that are involved in castings production. Basic characteristic and advantages of aluminium are presented. There are basic defects in this process introduced with special emphasis to cavitation erosion phenomena including cavitation theory. Cavitation erosion in die casting process is closely observed and explained. My research of cavitation erosion which appeared on aluminium casting is shortly presented
