Nā mea a me nā waiwai:
Hoʻokumu ʻia ka ʻeleʻele paʻa paʻa ma luna o kahi huila tungsten-cobalt (WC-Co), me ka maʻiʻo cobalt i hoʻoponopono ʻia i ka laulā o 6%-25% ma muli o ke ʻano o ka noi. Loaʻa ka microhardness o HRA89-93 i ka mea, kahi ikaika flexural o 3000-4000MPa, a me kahi koena hoʻonui wela o (4.5-6.5) × 10 ^ -6 / degere, e hōʻoia ana i ka paʻa o ke kūkulu ʻana i nā mahana a hiki i 800 degere. ʻO 20-30 mau manawa ke kiʻekiʻe o kona pale ʻana ma mua o ke kila mea hana, kūpono ia no nā noi friction kiʻekiʻe.
Kaʻina hana:
Aia ke kaʻina hana kumu
Hoʻomākaukau ʻia ʻo Powder Metallurgy: Hoʻohui ʻia a paʻi ʻia ka tungsten carbide a me ka pauka cobalt, a laila hoʻopaʻa ʻia ma lalo o ka vacuum ma 1360-1500 degere e hana i kahi ʻāpana paʻa.
ʻO ka wili pololei: Hoʻohana ʻia kahi huila wili daimana no ka hoʻoheheʻe ʻana i ka ʻili o ka nanometer{0}}, e loaʻa ana i kahi ʻōkeke o Ra0.02μm.
Hoʻomaʻamaʻa wela no ka hoʻoikaika ʻana: Hoʻohana ʻia ka nitriding haʻahaʻa haʻahaʻa no ka hoʻonui ʻana i ka paʻakikī o ka ʻili ma luna o HV1800.
Hoʻoponopono Hoʻolālā: Hoʻohana ʻia ka ʻenehana hoʻolālā gradient e hōʻoia i ka haʻahaʻa o ka ʻike cobalt i loko o ka ʻili o ka mold ma mua o ka loko, e kaulike ana i ke kūpaʻa a me ka paʻakikī.
Nā kahua noi:
I ka hana ʻoihana, hoʻohana nui ʻia ia ma nā wahi aʻe
Ka Hana Metala: Ke kaha ki'i a me ka hana 'ana i ka uwea φ0.1-20mm, me ka pololei o ± 0.005mm no ka hana uwea.
ʻO ka hana kaʻa: ʻO ke poʻo anu o nā apo noho valve engine, me kahi pūʻulu o nā mold hiki ke lōʻihi ma mua o 500,000 mau pōʻai.
ʻO ka Petroleum Extraction: Hana ʻia nā ʻāpana hoʻopaʻa ʻana i ka ʻili -sulfur valve sealing, hiki ke hana paʻa i loko o kahi kaiapuni me ka ʻike H2S o 15%.
ʻOihana Electronics: ʻO ke kahakaha pololei ʻana o nā papa alakaʻi, me ka palena haʻahaʻa haʻahaʻa o 0.003mm
