Ikhwalithi ephezulu eyenziwe eChina izinto zokusetshenziswa I-Cobalt chromium alloy particles CoCr Customized High-Entropy Alloys(HEA)

Ngenxa yokumelana nokugqokwa kwayo okuphezulu kanye nokuvumelana kwayo ne-biocompatibility, i-chrome yedayimane isetshenziswa kakhulu ekwenzeni amalunga okwenziwa, okuhlanganisa amalunga amadolo namajoyinti. Ama-alloys e-Co-Cr athambekele ekubeni amelane nokugqwala, anciphise izinkinga ngezicubu ezizungezile lapho etshaliwe, futhi abe nezakhiwo zamakhemikhali ezinciphisa amathuba okucasuka, ukungezwani nokungezwani komzimba, kanye nokusabela komzimba. Ama-alloys e-Co-Cr nawo asetshenziswa kabanzi ekwenzeni ama-stents nezinye izimila zokuhlinza ngoba ama-alloys e-Co-Cr nawo abonisa ukuhambisana okuhle kakhulu kwe-biocompatibility negazi nezicubu ezithambile. I-ASTM ejwayelekile yezimboni ichaza ukwakheka kwe-alloy yokufakelwa kwamathambo -F75: ikakhulukazi idayimane, equkethe i-chromium engama-27 kuye ku-30, isiliva engu-5 kuye ku-7%, ezinye izakhi ezibalulekile ezifana ne-manganese, i-silicon engaphansi kuka-1% ngayinye, insimbi engaphansi kuka-0.75%; i-nickel engaphansi kuka-0.5%, kanye nenani elincane kakhulu lekhabhoni, i-nitrogen, i-tungsten, i-phosphorus, isulfure, i-boron nokunye.

Ngokungeziwe kusiliva we-diamond chromium (CoCrMo), i-diamond nickel chromium (CoNiCrMo) nayo isetshenziswa ekufakweni. Ubuthi obungaba khona bama-N ions akhishwe ama-alloys e-CoNiCr kanye nezakhiwo zawo ezilinganiselwe zokungqubuzana kuwukukhathazeka lapho kusetshenziswa lawa ma-alloys njengeziphambano zomgwaqo. Ngalesi sizathu, i-CoCrMo imvamisa iyingxubevange eyinhloko yokushintshwa kwamalunga.

Ukupakisha kwethu okujwayelekile kungu-25kgs/Drum

Iphakheji ingenziwa ngendlela oyifisayo. isikhathi sokuthumela singaba ngolwandle, ngomoya, futhi isampula noma inani elincane lingathunyelwa nge-DHL, FEDEX, EMS kanye ne-TNT.
