Momwe Mungasinthire Magwiridwe a Tungsten Carbide?

Tungsten carbide ndi imodzi mwa zida zodziwika bwino zamafakitale amakono. Yafika nthawi yoti anthu azindikire kufunika ndi ntchito yayikulu ya tungsten carbide. Kugwiritsiridwa ntchito kwawo kwakukulu m'minda ya migodi ndi minda yamafuta kumayenderana ndi katundu wawo, monga kuuma kwakukulu, kukana kuvala, kukana mphamvu, kukana kugwedezeka, komanso kulimba. Popanga, anthu akutsata magwiridwe antchito apamwamba kwambiri kuti akwaniritse ntchito zovuta kwambiri, zomwe zimafunikira kuti azifufuza mwachangu ndikupanga zinthu za tungsten carbide. Anthu amayenera kuyika lingaliro lililonse lakukweza tungsten carbide kuti igwire ntchito. Nazi njira zina.

1. Sankhani bwino zopangira ndi binder ufa

Kuchita kwa tungsten carbide kumakhudzidwa makamaka ndi kapangidwe kake, tungsten carbide powder, ndi binder powder. Gawo la tungsten carbide ufa ndi binder lisintha kuuma kwawo. Monga tonse tikudziwa, tungsten carbide ndi yovuta kwambiri kuposa ufa wa binder, monga ufa wa cobalt. Chifukwa chake kuuma kumachulukirachulukira pomwe ufa wa cobalt umachepa. Koma osachepera a ufa wa cobalt ndi 3%, apo ayi, tungsten carbide idzakhala yovuta kugwirizanitsa pamodzi.

Ubwino wa zipangizo ndi zofunika. Choncho, tungsten carbide ufa ndi binder ufa ayenera kusankhidwa ndi kugula mosamala kwambiri. Ndipo zopangira ziyenera kuyeretsedwa 100%.

2. Sinthani kapangidwe ka tungsten carbide

Zonse zomwe zimaganiziridwa, kapangidwe kazinthu za tungsten carbide pambuyo pa sintered ziyenera kugawidwa mofanana. Ngati pali "dziwe la cobalt", zinthu za tungsten carbide izi ndizoletsedwa kugulitsa. Ndipo kukula kwa tinthu ting'onoting'ono kumatha kukhudzanso kapangidwe ka tungsten carbide. Popanga, ogwira ntchito ayenera kupewa tinthu tating'ono tating'ono ta tungsten carbide ufa kapena cobalt ufa kuti aletse tungsten carbide kupanga njere zolimba za tungsten carbide ndi maiwe a cobalt pakuwotcha.

3. Chithandizo chapamwamba

Nthawi zambiri, tigwiritsa ntchito njira zina monga kuumitsa pamwamba kuti tiwongolere magwiridwe antchito a tungsten carbide. Wogwira ntchito nthawi zambiri amayika TiC kapena TiN pamwamba pa zida za tungsten carbide.

4. Chithandizo cha kutentha

Kuchiza kutentha kumakhala kofala m'mafakitale, yomwe ndi njira yoyendetsedwa yomwe imagwiritsidwa ntchito posintha ma microstructure azitsulo ndikuwongolera magwiridwe antchito a tungsten carbide. Tengani zozungulira za shank mwachitsanzo. Tikayika mabatani m'thupi la mano, tizidutswa tating'onoting'ono timatenthedwa.

M'nkhaniyi, njira zinayi zowongolera magwiridwe antchito zikufotokozedwa. Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
