Timakutengerani kumalo opangira zinthu a WATT Carbide pa Zhuzhou kuti mukaone mmene zimapangidwira. Onani momwe zachitikira!

Zolemba Pafupifupi chilichonse chopangidwa ndi chitsulo chimapangidwa ndi choyikapo. Choyikacho chiyenera kupirira kutentha kwakukulu ndi mphamvu, kotero chimapangidwa ndi zinthu zovuta kwambiri padziko lapansi.

Choyikapo nthawi zonse chimapangidwa ndi 80% tungsten carbide ndi matrix achitsulo omwe amamangirira mbewu zolimba za carbide palimodzi, pomwe cobalt ndiyofala kwambiri. Zimatenga masiku oposa awiri kuti mupange choyikapo, choncho ndizovuta kwambiri.

M'nyumba yosungiramo zinthu, mizere ndi mizere yazinthu zopangira zimayikidwa. Tungsten carbide yomwe timagwiritsa ntchito ikuchokera kwa ogulitsa osankhidwa mosamala; gulu lililonse limayesedwa mosamala mu labu. Maphikidwe ena ali ndi zosakaniza zochepa zosankhidwa zomwe zimawonjezeredwa ndi manja. Zosakaniza zazikuluzikulu zimaperekedwa zokha pamalo oyima osiyanasiyana pamzere woyezera. Mu chipinda mphero zosakaniza ndi milled kuti chofunika tinthu kukula pamodzi ndi Mowa, madzi ndi organic binder.

Izi zimatenga maola asanu ndi atatu mpaka 55, malingana ndi maphikidwe. Dothi lotayirira limapoperedwa mu chowumitsira chopopera pomwe mpweya wotentha wa nayitrogeni umapopera kuti usungunuke mosakaniza wa ethanol ndi madzi. Ufawo ukauma, umakhala ndi tinthu tozungulira tofanana. Chitsanzo chimatumizidwa ku labu kuti chiwunikidwe bwino. Migolo ya 100 kilogalamu ya ufa wokonzeka kusindikiza imafika pamakina osindikizira. Chomangira chomwe chimawonjezedwa mu chipinda chophera ndi chomangira chomwe chimamangirira ufa pamodzi mukanikikiza.

Kupanikizika kwa matani 12 kumagwiritsidwa ntchito, kutengera mtundu wa kuyikapo. Chomangira chomwe chimawonjezedwa mu chipinda chogayira ndichomwe chimasunga ufa pamodzi mukanikikiza. Njirayi ndi yokha basi. Choyika chilichonse chimayesedwa ndipo pazigawo zina zimayendetsedwa mowoneka ndi woyendetsa. Zoyikapo zopanikizidwa ndizowonongeka kwambiri ndipo zimafunikira kuumitsa mu uvuni wotentha. Izi zimatenga pafupifupi maola 13 pa kutentha pafupifupi 1,500 digiri Celsius. Zoyikapo zimayikidwa mu chinthu cholimba kwambiri cha simenti-carbide, cholimba ngati diamondi.

organic binder yatenthedwa ndipo choyikapo chimachepa pafupifupi theka la kukula kwake koyambirira. Kutentha kowonjezereka kumagwiritsidwanso ntchito kutenthetsa malo m'nyengo yozizira, ndi kuwaziziritsa m'nyengo yachilimwe. Zoyikapo zimakhala pansi, imodzi ndi imodzi, mumitundu yosiyanasiyana ya makina opera kuti akwaniritse kukula kwake, geometry ndi kulolerana. Popeza choyikapo simenti cha carbide ndi cholimba kwambiri, disc yokhala ndi ma diamondi ang'onoang'ono 150 miliyoni, imagwiritsidwa ntchito popera. Carbide yowonjezera imasinthidwanso, komanso mafuta omwe amagwiritsidwa ntchito ngati kudula madzi.

Zoyikapo zambiri zimakutidwa, mwina kudzera mu chemical vapor deposition (CVD) kapena physical vapor deposition (PVD). Apa, tikuwona ndondomeko ya PVD. Zoyikapo zimayikidwa muzitsulo ... ... ndikuyika mu uvuni. Chophimba chopyapyalacho chimapangitsa choyikapo kukhala cholimba komanso cholimba. Apa ndipamenenso choyikacho chimapeza mtundu wake weniweni.

Ngakhale choyikacho chimawunikiridwa ku labu nthawi zonse panthawi yonseyi, chimawunikidwanso pamanja musanachizidwe chizindikiro ndi kupakidwa. Pambuyo polemba, mabokosi otuwa ali okonzeka kutumizidwa kwa opanga padziko lonse lapansi.
