Momwe mungadziwire mtundu wa aloyi yamkuwa

Momwe mungadziwire mtundu waaloyi yamkuwa?
Mkuwa woyera, mkuwa, mkuwa wofiira (wotchedwanso "mkuwa wofiira"), ndi bronze (buluu-imvi kapena imvi-chikasu) amasiyanitsidwa ndi mtundu.Pakati pawo, mkuwa woyera ndi mkuwa ndizosavuta kusiyanitsa;mkuwa wofiira ndi mkuwa woyera (zonyansa <1%) ndi bronze (zigawo zina za alloy zili pafupi 5%), zomwe zimakhala zovuta kuzisiyanitsa.Pamene unoxidized, mtundu wa mkuwa wofiira umakhala wowala kuposa wamkuwa, ndipo mkuwa ndi wobiriwira pang'ono kapena wachikasu;pambuyo pa okosijeni, mkuwa wofiira umakhala wakuda, ndipo mkuwa ndi turquoise (oxidation woopsa wa madzi) kapena chokoleti.
Gulu ndi kuwotcherera makhalidwe a mkuwa ndi mkuwa aloyi:
(1) Mkuwa weniweni: Mkuwa weniweni nthawi zambiri umatchedwa mkuwa wofiira.Ili ndi madulidwe abwino amagetsi, matenthedwe amafuta komanso kukana dzimbiri.Mkuwa woyera umayimiridwa ndi chilembo + T}} (mkuwa), monga Tl, T2, T3, etc. Mpweya wa okosijeni ndi wochepa kwambiri, ndipo mkuwa woyera wosapitirira 0.01% umatchedwa mkuwa wopanda oxygen, womwe umaimiridwa ndi TU (mkuwa wopanda), monga TU1, TU2, ndi zina zotero.
(2) Brass: Aloyi yamkuwa yokhala ndi zinki monga gawo lalikulu la alloying limatchedwa brass.Mkuwa umagwiritsa ntchito + H;(chikasu) amatanthauza H80, H70, H68, ndi zina.
(3) Bronze: Kale, aloyi wa mkuwa ndi malata ankatchedwa bronze, koma masiku ano zinthu zina za mkuwa, osati mkuwa zimatchedwa bronze.Zomwe zimagwiritsidwa ntchito kwambiri ndi tin bronze, aluminium bronze ndi min bronze.Mkuwa umaimiridwa ndi "Q" (cyan).
Makhalidwe awotcherera amkuwa ndi aloyi zamkuwa ndi awa: ① zovuta kuphatikiza komanso zosavuta kupunduka;② zosavuta kupanga ming'alu yotentha;③ zosavuta kupanga pores
Kuwotcherera kwa mkuwa ndi mkuwa kumatengera kuwotcherera kwa mpweya, kuwotcherera kwa inert, kuwotcherera kwa arc pansi pamadzi, kuwotcherera ndi njira zina.
Ma aloyi amkuwa ndi amkuwa amakhala ndi matenthedwe abwino, motero ayenera kutenthedwa asanawotchedwe, ndipo mphamvu yayikulu iyenera kugwiritsidwa ntchito powotcherera.Kuwotcherera kwa hydrogen tungsten arc kumatengera kulumikizana kwa DC kwabwino.Powotcherera mpweya, lawi losalowerera ndale kapena lawi lofooka la carbonization limagwiritsidwa ntchito ngati mkuwa, ndipo lawi lofooka la oxidizing limagwiritsidwa ntchito ngati mkuwa kuteteza kutuluka kwa zinki.
