Qaababka heerkulka sare leh ayaa ah khatarta ugu weyn ee ku iman karta cimriga qaybta PDC. Grafitization-ka uu keeno Cobalt iyo cadaadiska kulaylka ayaa sababa jajab hore iyo guuldarro. Qoto dheer oo si habboon loo daadiyo ayaa ah xalka muhiimka ah—Ninestones Superabrasives-na waxay ku takhasustay sayniskan.ODM Ilkaha PDC Bittaxane.
Sababta Cobalt u Burburiso Xasilloonida Kulaylka (Xogta Warshadaha)
Sida uu xaqiijiyayDheemanka iyo Agabka La XiriiraiyoShannon Abrasives, xidhmada kobalt-ku waxay si dhakhso leh uga fidsan tahay dheemanka heerkul sare, taasoo abuurta cadaadis gudaha ah. Marka heerkulku ka sarreeyo 700°C, kobalt-ku wuxuu kiciyaa garaafka dheemanka, isagoo si dhakhso ah u luminaya adkaanta iyo iska caabbinta xirashada.
Gooyayaasha caadiga ah ee aan la daadin ayaa si dhakhso ah ugu fashilma ceelasha kulul. Kaliya daadinta la xakameeyey ayaa xakamayn karta dhaawacan.
Qoto dheer oo la daadinayo: Beddelka Waxqabadka Dhabta ah
Daadinta ayaa ka saarta kobalt-ka dusha sare si loo joojiyo qudhunka kulaylka.Dib u Eegista Dheemanka Warshadahawaxay muujinaysaa:
- 80–120μm oo daadin ah:waxay kordhisaa xadka kulaylka ilaa ~900°C
- 180–220μm daadinta:kor u kaca heerkulka ilaa 1100°C +
Aad u dhuuban = iska caabin kulayl oo xaddidan; aad u qoto dheer = waxay daciifisaa xoogga geeska.
