ʻO ka mīkini wili PDC a i ʻole PCD? He aha ka ʻokoʻa?
ʻO ka ʻāpana wili PDC ʻo ia hoʻi ka ʻāpana kumu o ka Polycrystalline Diamond Cutter
ʻO nā luawai mua loa, he mau lua wai ia, nā lua pāpaʻu i ʻeli ʻia e ka lima ma nā wahi i hoʻokokoke aku ai ka papa wai i ka ʻili, ʻo ka maʻamau me nā paia pōhaku a lāʻau paha e uhi ana i ka lua.
Hana ʻia nā PDC ma ka hoʻohui ʻana i kekahi mau papa o nā daimana polycrystalline (PCD) me kahi papa o ka liner carbide cemented ma ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe.
ʻO nā PDC kekahi o nā mea hana daimana paʻa loa.
ʻO PCD wale nō ke ʻano o Polycrystalline Diamond:
Hana ʻia nā PCD ma ka sintering ʻana i nā kristal daimana hoʻokahi micro-size he nui ma ke ana wela kiʻekiʻe a me ke kaomi kiʻekiʻe.
He paʻakikī maikaʻi ka PCD i ka haki ʻana a me ke kūpaʻa wela maikaʻi, a hoʻohana ʻia i ka hana ʻana i nā ʻāpana wili honua.
Loaʻa iā PDC nā pono o ke kūpaʻa kiʻekiʻe o ka daimana me ka paʻakikī maikaʻi o ka carbide.
