Cobalt Chrome Alloy Round Bar
Cobalt Chrome Alloy Round Bar
Cobalt Chrome Alloy Round Bar (cobalt-chromium-molybdenum) yog cobalt-raws li alloy, tseem hu ua ib hom ntawm Stellite alloy. Nws yog cobalt-based alloy uas tiv taus hnav thiab corrosion. Thaum ntxov cobalt-raws li alloys yog cobalt-chromium binary alloys, thiab tom qab ntawd tsim mus rau hauv ternary cobalt-chromium-tungsten alloys, thiab tom qab ntawd tsim rau hauv cobalt-chromium-molybdenum alloys. Cobalt-chromium-molybdenum nrog cobalt yog lub ntsiab tivthaiv thiab ib qho me me ntawm npib tsib xee, carbon thiab lwm yam alloying ntsiab, qee zaus kuj muaj hlau, yog cov khoom tseem ceeb ntawm cobalt-chromium-molybdenum alloys. Raws li cov khoom siv hauv cov hlau, nws tuaj yeem ua rau vuam hlau, tawv saum npoo av, thermal txau, tshuaj tsuag vuam thiab lwm yam txheej txheem, thiab tseem tuaj yeem ua rau hauv castings thiab forgings, hmoov metallurgy qhov chaw.
Cobalt Chrome Alloy Round Bar yog ob lub ntsiab lus ntawm cobalt-based alloys, thaum ntxiv ntawm molybdenum tuaj yeem tau txais cov nplej zoo dua thiab muaj zog dua tom qab casting lossis forging. Cobalt-chromium-molybdenum alloys tau muab faib ua ob pawg: CoCrMo alloys thiab CoNiCrMo alloys;
1. Ib qho yog CoCrMo alloy, feem ntau yog cov khoom cam khwb cia. Tom qab kev txhim kho deformed cobalt-chromium-molybdenum alloy cov khoom, kev txhim kho ntawm cov txheej txheem tau zoo heev txhim kho cov khoom siv txhua yam ntawm cov khoom;
2. Lwm hom yog CoNiCrMo alloy, 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.
Cobalt Chrome Alloy Round Bar Daim duab:
Cobalt Chrome Alloy Round Bar muaj kev tiv thaiv zoo rau kev sib txhuam, cavitation, mortar abrasion thiab thermal hnav. Cov alloy kuj muaj cov khoom zoo corrosion. Txawm tias kub liab kub ntawm 480 degree, nws tseem muaj hardness zoo heev, lub zog thiab hnav tsis kam.
