Kev siv Cobalt Chromium Molybdenum Alloys
CoCrMo alloy (cobalt chromium molybdenum) yog ib hom cobalt-raws li alloy, thiab kuj yog ib hom ntawm feem ntau hu ua Stellite alloy. Nws yog ib hom cobalt-based alloy uas tuaj yeem tiv taus hnav thiab corrosion. Thawj cobalt-raws li alloy yog cobalt-chromium binary alloy, uas tom qab ntawd tau tsim los ua ib tug cobalt-chromium-tungsten ternary muaj pes tsawg leeg, thiab ces ib tug cobalt-chromium-molybdenum alloy tau tsim tom qab. Cobalt-chromium-molybdenum alloy yog ib hom hlau alloy nrog cobalt ua lub ntsiab tivthaiv, muaj ntau ntawm chromium, molybdenum thiab ib qho me me ntawm npib tsib xee, carbon thiab lwm yam alloying ntsiab lus, thiab qee zaus hlau. Raws li cov khoom sib txawv hauv cov hlau, lawv tuaj yeem ua rau vuam hlau, hmoov siv rau cov tawv tawv saum npoo, thermal txau, tshuaj tsuag vuam thiab lwm yam txheej txheem, thiab tseem tuaj yeem ua rau hauv castings thiab forgings thiab hmoov metallurgy qhov chaw.
Cobalt thiab chromium yog ob lub ntsiab lus tseem ceeb ntawm cobalt-based alloys, thiab qhov sib ntxiv ntawm molybdenum tuaj yeem tau txais cov nplej zoo dua thiab muaj zog dua tom qab casting lossis forging. Cobalt-chromium-molybdenum alloys yeej muab faib ua ob pawg: ib qho yog CoCrMo alloys, uas feem ntau yog cov khoom cam khwb cia, thiab lwm yam yog CoNiCrMo alloys, uas feem ntau precision machined los ntawm (kub) forging. Cam khwb cia CoCrMo alloys tau siv hauv kev kho hniav ntau xyoo thiab tam sim no siv los ua cov pob qij txha, thiab forged CoNiCrMo alloys yog siv los ua cov pob qij txha hnyav xws li hauv caug thiab lub duav. Txawm li cas los xij, raws li cov khoom cog cog, CoCrMo alloy yuav tso Co, Cr, Ni thiab lwm yam teeb meem ions rau tib neeg lub cev tom qab cog rau hauv tib neeg lub cev.
