Kodi zovuta za laser kudula kwachitsulo wamba ndi superalloy ndi ziti?

Zida zazikulu zodulira makina odulira laser ndi chitsulo chosapanga dzimbiri, chitsulo cha aloyi, chitsulo, aluminium, zinki, magnesium ndi aloyi zina.Zida zosiyanasiyana zimakhala ndi kuuma kosiyana komanso zovuta zodula.Otsatirawa akatswirilaser kudula makina opangaAmuna-Mwayi amafotokoza zovuta za laser kudula kwazitsulo wamba ndi ma alloys otentha kwambiri.

1. Zinthuzo zimakhala ndi matenthedwe abwino
Pamene laser kudula makina amadula aloyi, izo kupanga kwambiri kudula kutentha, amene amanyamula ndi mpopi kutsogolo, ndi nsonga ya mpeni amanyamula laser kudula kutentha 700-9000 °.Pansi pa kutentha kwakukulu kumeneku ndi mphamvu yodula, m'mphepete mwake mudzatulutsa pulasitiki, kugwirizanitsa ndi kuvala.

2. Large laser kudula mphamvu
Mphamvu za superalloys ndizoposa 30% kuposa zazitsulo za alloy zomwe zimagwiritsidwa ntchito kwambiri pama turbines a nthunzi.Pa kutentha kodula pamwamba pa 600 ° C, mphamvu ya ma superalloys opangidwa ndi nickel akadali apamwamba kuposa azitsulo wamba aloyi.The unit kudula mphamvu ya osalimba mkulu-kutentha aloyi ndi pamwamba 3900N/mm2, pamene wamba zitsulo aloyi ndi 2400N/mm2 yekha.

3. Chizoloŵezi chachikulu chogwira ntchito mowumitsa
Mwachitsanzo, kuuma kwa gawo lapansi losalimba la GH4169 kuli pafupi ndi HRC37.Pambuyo kudula ndi zitsulo laser kudula makina, wosanjikiza anaumitsa pafupifupi 0.03mm adzapangidwa pamwamba, ndipo kuuma adzawonjezeka pafupifupi HRC47, ndi digiri kuumitsa mpaka 27%.Chodabwitsa cha kuuma kwa ntchito kumakhudza kwambiri moyo wapampopi wokhala ndi ma oxidized front, zomwe nthawi zambiri zimabweretsa kuvala kwamalire.

Kunena zoona, zida wamba ndizabwinoko kudulira, ndipo zida za alloy zotentha kwambiri zolimba kwambiri zimakhala zovuta kudulira.Njira zosiyanasiyana zodulira ziyenera kuperekedwa pamavuto osiyanasiyana odula.Kuti mudziwe zambiri za laser kudula, chonde onani Men-Luckzida zodulira laserwopanga.
