Momwe mungasinthire makonda a carbide opangidwa mwapadera?

M’yoyo tukusosekwa kumanyilila yindu yine yampaka tukombolece. Kodi mukudziwa momwe zinthu zopangira simenti zowoneka ngati mwapadera zimapangidwira? Pali njira zambiri zopangira zitsulo, koma njira yomwe imagwiritsidwa ntchito kwambiri ndi kudula. Ndiye mungapangire bwanji ndi kukonza magawo opangidwa ndi simenti apadera a carbide?

Tiyeni tiyambe ndikuyang'ana njira yopangira simenti ya carbide:

Choyamba, tungsten carbide imasakanizidwa ndi cobalt kupanga ufa womwe ukhoza kugawidwa ngati chakudya. Thirani chisakanizo cha granular mu nkhungu ndikusindikiza. Ili ndi mphamvu yapakatikati ngati choko. Kenaka, chopukutiracho chimayikidwa mu ng'anjo yotentha ndikutenthedwa kutentha pafupifupi 1400 ° C, zomwe zimapangitsa kuti carbide ikhale ndi simenti.

Ndiye timapanga bwanji carbide yolimba iyi kukhala gawo lopangidwa ndi carbide?

1. Zida zomwe zimafunikira popanga zinthu zopangidwa ndi simenti yapadera za carbide zimasakanizidwa mwamphamvu, ndipo zosakaniza zomwe zimapezeka nthawi zambiri zimatchedwa zopangira.

2. Mawonekedwe omwe amafunidwa a carbide opangidwa ndi simenti yapadera amapangidwa mu makina opangira jakisoni apulasitiki. Kutengera mawonekedwe a polima omwe amagwiritsidwa ntchito polima matrix, zopangirazo zimatenthedwa mpaka pafupifupi 100-240 ° C kenako ndikukanikizira mubowo la mawonekedwe omwe mukufuna. Pambuyo pozizira, gawo lopangidwa limatulutsidwa kuchokera pamimba ndikuchotsedwa.

3. Chotsani zomatira pazigawo zopangidwa. Opaleshoniyo iyenera kuchitika m'njira yoti pasakhale ming'alu yomwe imapangidwa muzambiri za carbide. Zomatira zimatha kuchotsedwa m'njira zosiyanasiyana. Chomangiracho chimachotsedwa ndi kutentha kapena kutulutsa mu chosungunulira choyenera kapena kuphatikiza zonse ziwiri.

4. Sintering kwenikweni ikuchitika chimodzimodzi monga zida kukanikiza mbali.

Pamwambapa ndi njira yopanga simenti carbide mbali zapadera zoboola pakati, ngati mukufuna makonda wapadera woboola pakati simenti carbide, mukhoza kulankhula zhuzhou chuangrui simenti fakitale carbide nthawi iliyonse. Zogulitsa zathu za carbide zosapanga dzimbiri zokhala ndi mawonekedwe apadera zimaphimba zinthu zambiri kuti zikwaniritse zosowa za makasitomala m'mafakitale osiyanasiyana.
