Hana ʻia ka maikaʻi kiʻekiʻe ma Kina mau mea waiwai Cobalt chromium alloy particles CoCr Customized High-Entropy Alloys(HEA)

Ma muli o kona kūpale kiʻekiʻe a me ka biocompatibility, hoʻohana pinepine ʻia ka diamond chrome i ka hana ʻana i nā hui artificial, me nā hui kuli a me nā hui. ʻO nā huila Co-Cr ke kūpaʻa i ka corrosion, e hōʻemi i nā pilikia me ka ʻiʻo a puni ke hoʻokomo ʻia, a loaʻa iā ia nā waiwai kemika e hōʻemi i ka hiki ke hoʻonāukiuki, nā maʻi maʻi, a me nā hopena kūlohelohe. Hoʻohana nui ʻia nā ʻāpana Co-Cr i ka hana ʻana i nā stents a me nā mea hoʻokomo ʻokoʻa ʻē aʻe no ka mea hōʻike pū ʻia nā alloys Co-Cr i ka biocompatibility maikaʻi loa me ke koko a me nā ʻiʻo palupalu. ʻO ka maʻamau o ka ʻoihana ASTM e wehewehe i ka haku mele no nā implants orthopedic -F75: ka nui o ke daimana, aia ka 27 a 30% chromium, 5 a 7% kālā, nā mea koʻikoʻi ʻē aʻe e like me ka manganese, silika ma lalo o 1% kēlā me kēia, hao ma lalo o 0.75%, nickel emi ma lalo o 0.5%, a me ka liʻiliʻi loa o carbon, nitrogen, tungsten, phosphorus, sulfur, boron a pēlā aku.

Ma waho aʻe o ke kālā chromium daimana (CoCrMo), hoʻohana pū ʻia ka diamond nickel chromium (CoNiCrMo) i nā implants. ʻO ka hiki ke ʻona o nā ion N i hoʻokuʻu ʻia e nā huila CoNiCr a me kā lākou mau waiwai frictional liʻiliʻi e hopohopo i ka wā e hoʻohana ai i kēia mau alaleʻa ma ke ʻano he kuʻekuʻe. No kēia kumu, ʻo CoCrMo ka mea mua loa no ka hoʻololi ʻana i ka hui.
