Apstrakt
Proces sačmarenja je vrlo važan i dobro poznat proces otvrdnjavanja na hladno kojim se produžava radni vek različitih mašinskih delova i površina alata, s obzirom da on poboljšava zamornu čvrstoću i korozionu otpornost opterećenih površina. Ojačavanje sačmarenjem, zbog plastične deformacije, obezbeđuje povećanje tvrdoće i indukuje pritisne zaostale napone u tankom površinskom sloju, čime se smanjuje zamor i sprečava stvaranje i širenje prslina. U radu su prikazani rezultati ojačavanja sačmarenjem uzoraka izrađenih od aluminijumske legure 7075-T651. Stanje površine posle sačmarenja procenjeno je u odnosu na integritet površine, čime se uspostavlja zavisnost između uslova procesa i hrapavosti i dubine ojačanog sloja. Sve to je podržano analizom promena zaostalih napona.
