Hunhu hwepamusoro hwakagadzirwa muChina mbishi zvinhu Cobalt chromium alloy particles CoCr Yakagadzirirwa Yakakwira-Entropy Alloys(HEA)

Nekuda kwekupfeka kwayo kwakanyanya kuramba uye biocompatibility, diamond chrome inonyanya kushandiswa mukugadzira majoini ekugadzira, kusanganisira mabvi nemajoini. Co-Cr alloys anowanzoita corrosion resistant, kuderedza kunetsa nematishu akatenderedza kana akadyarwa, uye ane makemikari zvimiro zvinoderedza mukana wekutsamwiswa, allergic reaction, uye immune reaction. Co-Cr alloys anoshandiswawo zvakanyanya mukugadzira stents uye mamwe ma implants ekuvhiya nekuti maCo-Cr alloys anoratidzawo yakanakisa biocompatibility neropa uye zvinyoro zvinyoro. Iyo indasitiri chiyero ASTM inotsanangura alloy kuumbwa kwemapfupa anodyara -F75: kunyanya dhaimondi, ine 27 kusvika 30% chromium, 5 kusvika 7% sirivha, zvimwe zvakakosha zvinhu senge manganese, nesilicon isingasviki 1% imwe neimwe, simbi isingasviki 0.75%, nickel isingasviki 0.5%, uye shoma shoma kabhoni, nitrogen, tungsten, phosphorus, sarufa, boron zvichingodaro.

Pamusoro pedhaimondi chromium sirivheri (CoCrMo), diamond nickel chromium (CoNiCrMo) inoshandiswawo mukudyara. Iyo inogoneka huturu hweN ions yakaburitswa neCoNiCr alloys uye yavo shoma yekukakavadzana zvimiro zvinonetsa kana uchishandisa aya alloys semharadzano. Nechikonzero ichi, CoCrMo inowanzova iyo yekutanga alloy yekudzoreredza majoini.

Yedu yakajairika kurongedza ndeye 25kgs / Drum

Iyo yekurongedza inogona kugadzirwa. nguva yekutumira inogona kuva negungwa, nemhepo, uye sampuli kana diki diki inogona kutumirwa neDHL, FEDEX, EMS uye TNT.
