Kukutengerani ku tungsten carbide porosity

Tungsten carbide ndi chinthu cholimba komanso cholimba chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera monga mphamvu, kukana kuvala, komanso kuuma.Komabe, monga zakuthupi zilizonse, sizikhala zopanda ungwiro, ndipo porosity ndi imodzi mwazinthu zomwe zimagwirizanitsidwa nditungsten carbide.

Porosity mutungsten carbideamatanthauza kupezeka kwa voids, ming'alu, kapena mipata mkati mwa zinthu zomwe zingafooketse kapangidwe kake ndi magwiridwe ake.Ma poreswa amatha chifukwa cha zinthu zosiyanasiyana, kuphatikizapo njira zopangira zolakwika, kusagwirizana kwa zinthu zomwe zimagwiritsidwa ntchito, komanso kusiyana kwa njira yopangira sintering.

Porosity mu tungsten carbide imatha kukhudza kwambiri zinthu ndi magwiridwe ake.Kuchuluka kwa porosity kumatha kuchepetsa kulimba kwa zinthu, kulimba, komanso kulimba, zomwe zimapangitsa kuti zikhale zosavuta kusweka ndi kuvala.Kuphatikiza apo, porosity imatha kusokoneza kuthekera kwazinthu kuyendetsa kutentha, zomwe zingayambitse zovuta monga kusweka kwamafuta ndi kupindika.

Kuti muchepetse porosity mu tungsten carbide, opanga amatha kugwiritsa ntchito njira zapadera monga kukanikiza kotentha kwa isostatic, komwe kungathandize kutseka ma pores aliwonse pazinthuzo.Kukanikiza kotentha kwa isostatic kumaphatikizapo kugwiritsa ntchito kuthamanga kwambiri ndi kutentha kuzinthu za tungsten carbide, zomwe zimathandiza kuchotsa mipata, voids, kapena ming'alu yazinthuzo.Zonse,

porosity ndi nkhani yodziwika bwino yokhudzana ndi tungsten carbide, koma imatha kuchepetsedwa pogwiritsa ntchito njira ndi njira zopangira zoyenera, komanso posankha zida zapamwamba kwambiri.
