Kufunika Kwa Kupaka Tungsten Carbide

Kupanga tungsten carbide mankhwala, tiyenera kukonzekera zopangira choyamba, kuphatikizapo tungsten carbide ufa ndi binder ufa. Kenako tiyenera kusakaniza ndi mphero mu makina mphero mpira, kuwaza iwo mu dryer sprayer, ndi compact iwo mu mawonekedwe ndi kukula kwake. Pambuyo mndandanda wa njira, tiyenera sinter iwo mu ng'anjo sintering. Izi ndizopanga zonse kuti zilimbikitse magwiridwe antchito a tungsten carbide. Tidzaumitsa tungsten carbide ndi chithandizo chapamwamba. Nkhaniyi ikuyang'ana kwambiri zokutira tungsten carbide.

Kupanga tungsten carbide workpiece kumafuna nthawi yayitali. Popanga, tidzavala tungsten carbide kuti tipewe oxidation pansi pa kutentha kwambiri. Tungsten carbide yokutidwa imakhala ndi kuuma kwambiri, kukana kuvala, kusasunthika kwamankhwala, komanso kukangana kochepa komanso kusinthasintha kwamafuta.

Kupaka tungsten carbide kuli ndi njira ziwiri: imodzi ndi CVD, ndipo ina ndi PVD.

Chemical vapor deposition imatchedwanso CVD mwachidule. Mfundo yoyikapo mpweya wamankhwala ndi momwe zimakhalira ndi mankhwala omwe amapangidwa ndi thermally pamwamba pa zinthu zotentha za tungsten carbide, zomwe zimapangidwanso kuti zigwirizane ndi zida zatsopano komanso makampani a semiconductor.

Kuyika kwa nthunzi pathupi kumatchedwanso PVD mwachidule, yomwe ndi njira yopangira mpweya kuyika zinthu zopyapyala pazinthu za tungsten carbide. Nthawi zonse imakhala ndi masitepe anayi, evaporation, mayendedwe, kachitidwe, ndi deposition. Izi zidzachitika mu chipinda cha vacuum ndipo amagwiritsa ntchito vacuum yoyera ndi youma.

Zovala zimakhala ndi kuuma kwambiri komanso kukana kuvala. Poyerekeza ndi zinthu za tungsten carbide popanda zokutira, zinthu za tungsten carbide zokhala ndi zokutira zimatha kugwira ntchito mwachangu kwambiri, zomwe zingapangitse kupanga bwino. Kuonjezera apo, pamene mankhwala a tungsten carbide okhala ndi zokutira komanso opanda zokutira akugwira ntchito pa liwiro lomwelo lodula, ma tungsten carbide okhala ndi zokutira amakhala ndi kukana kwapamwamba kwambiri.

Nthawi zambiri, tungsten carbide iyenera kuphimbidwa, makamaka zoikamo za tungsten carbide. Kupaka kwa tungsten carbide kumatha kusintha kunyowa komanso kuuma komanso kuteteza tungsten carbide ku kutentha kwambiri, okosijeni, ndi dzimbiri. Chophimbacho ndi chofunikira kwambiri pa tungsten carbide.

Kupatula zokutira, palinso njira zina zoumitsira tungsten carbide pochiza pamwamba, monga kuyika kwa plasma, kupopera mbewu mankhwalawa kwamphamvu kwambiri, kuwotcherera chishango cha gasi, kuwotcherera kwa chishango cha gasi, kuyika moto, kutsekereza vacuum, ndi kuuma kwa kutentha.

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.
