Mapangidwe otentha kwambiri ndiye chiwopsezo chachikulu pa kulimba kwa ma bit a PDC. Kujambula kwa Cobalt komwe kumachitika chifukwa cha kuzizira komanso kupsinjika kwa kutentha kumayambitsa kusweka ndi kulephera msanga. Kuzama koyenera kwa leaching ndiye yankho lofunikira - ndipo Ninestones Superabrasives imachita bwino sayansi iyi muMano a ODM PDC Bitmndandanda.
Chifukwa Chake Cobalt Imawononga Kukhazikika kwa Kutentha (Zambiri za Makampani)
Monga momwe zatsimikiziridwa ndiDaimondi ndi Zipangizo ZofananandiShannon Abrasives, cobalt binder imakula mofulumira kuposa diamondi pa kutentha kwakukulu, zomwe zimapangitsa kuti mkati mwake mukhale ndi nkhawa. Pamwamba pa 700°C, cobalt imayambitsa graphitization ya diamondi, kutaya kuuma kwake komanso kukana kukalamba msanga.
Zipangizo zodulira zosagwiritsidwa ntchito ndi leaching zimalephera msanga m'zitsime zotentha. Kuchotsa leaching kolamulidwa kokha ndiko kungachepetse kuwonongeka kumeneku.
Kuzama kwa Leaching: Kusinthana Kwabwino Kwambiri
Kutulutsa madzi kuchokera ku zinthu zosungunuka kumachotsa cobalt pamwamba kuti kutentha kuchepe.Ndemanga ya Daimondi Yamakampaniziwonetsero:
- Kutulutsa madzi kwa 80–120μm:kumawonjezera malire a kutentha kufika pa ~900°C
- Kutulutsa madzi kwa 180–220μm:kutentha kumawonjezeka kufika pa 1100°C+
Kusaya kwambiri = kukana kutentha pang'ono; kuzama kwambiri = kufooketsa mphamvu ya m'mphepete.
Ninestones amawerengeraMano a ODM PDC Bit to Kuzama kwabwino kwa leaching ndi 160–200μmkuti ikhale yolimba kwambiri popanda kutaya kulimba.

Zokhudza Wolemba
Ryan Ford, Perth, Australia, wagwira ntchito yoboola ndi ukadaulo wa PDC kwa zaka 20. Amadziwika bwino pa kukhazikika kwa kutentha komanso kukonza bwino kuboola ku Australia, South Asia, ndi NZ. Amalimbikitsa Ninestones Superabrasives kuti azitha kuyendetsa bwino ntchito yoboola komanso yodalirika.Mano a ODM PDC Bit"Kapangidwe kawo kotulutsa madzi ndi kabwino kwambiri m'gulu - kokhazikika, kolimba, komanso kosatentha.
