Raws li peb txhua tus paub, magnesium alloys yog ua los ntawm cov hlau magnesium thiab tsim los ntawm kev ntxiv qee cov ntsiab lus. Cov ntsiab lus alloy ntxiv hauv magnesium alloys feem ntau suav nrog AL, Zn, Mn, Si, x, Cu, Li thiab qee lub ntiaj teb tsis tshua muaj. Magnesium alloys tuaj yeem faib tsis tau tsuas yog los ntawm kev sib xyaw alloy, tab sis kuj los ntawm kev ua cov txheej txheem thiab kev ua haujlwm. Niaj hnub no, Nuoba tau cog lus tias yuav piav qhia txog kev faib tawm ntawm magnesium alloys thiab dab tsi yog magnesium alloy kev kho saum npoo?
Kev ua ntawm magnesium alloy qhov chaw
Kev faib tawm ntawm magnesium alloys:
1. Kev faib tawm raws li magnesium alloy muaj pes tsawg leeg:
Raws li cov tshuaj muaj pes tsawg leeg, nws tuaj yeem muab faib ua Mg Mn, Mg AL Mn, Mg Al Zn Mn, Mg Zn Zn, Mg Zr, Mg Zn Zr, Mg Re Zr, Mg Ag Re Zr, Mg Y-Re Zr tsib lub ntsiab alloy ntsiab Mn, Al, Zn, Zr thiab tsis tshua muaj ntiaj teb.
2. Kev faib tawm raws li kev ua haujlwm ntawm magnesium alloy:
Raws li txoj kev ua, magnesium alloys tau muab faib ua peb pawg: cam khwb cia magnesium alloys, wrought magnesium alloys thiab kub-dip magnesium alloys. Casting thiab deformation yog ob hom. Ob hom alloys no muaj qhov sib txawv loj hauv kev sib xyaw thiab cov qauv hlau thiab cov khoom. Cam khwb cia magnesium alloys yog tsuas yog siv rau tuag casting khoom thauj khoom, machinery, hluav taws xob thiab hluav taws xob khoom thiab lwm yam spare qhov chaw. Tuag cam khwb cia magnesium alloy workpieces muaj siab casting efficiency, zoo heev nto zoo, nplua thiab zoo li cov nplej, thiab muaj peev xwm tsim workpieces nrog nyias phab ntsa thiab complex duab. Wrought magnesium alloys feem ntau yog siv rau forging thiab extrusion, nrog lub zog siab thiab zoo plasticity.
3. Kev faib tawm raws li cov khoom thiab kev siv ntawm magnesium alloys:
Nws tuaj yeem muab faib ua creep resistant magnesium alloy, magnesium alloy pwm, hnav-resistant magnesium alloy, anti-corrosion magnesium alloy thiab structural magnesium alloy.
Kev ua ntawm magnesium alloy qhov chaw
Kev ceev faj rau magnesium alloy ua deg kho:
Vim tias nws cov ntom ntom nti thiab lub zog siab, cov hlau nplaum siab, cov khoom siv ntsuab, uas tuaj yeem tiv thaiv cov khoom ntsuab ntxiv lawm, thiab yog siv dav hauv kev ua haujlwm tsheb. Txawm li cas los xij, kev ua haujlwm kub thiab kev tiv thaiv corrosion ntawm magnesium alloys tsis zoo, uas yuav tsum muaj qee qhov kev hloov kho saum npoo los yog txheej txheej los txhim kho kev ua haujlwm ntawm magnesium alloys. Kev kho deg ntawm magnesium alloy feem ntau suav nrog cov hauv qab no:
1. Magnesium alloy pretreatment:
Tshem tawm cov roj stain, xeb thiab lwm yam txawv teb chaws uas txuas rau saum npoo ntawm magnesium alloy kom tau ib txheej hauv qab uas tuaj yeem cais qhov chaw. Cov kev kho mob feem ntau suav nrog kev tu txhua yam thiab tshuaj ntxuav.
2. Magnesium alloy electroplating / electroless plating:
Tiv thaiv magnesium alloy matrix thiab txhim kho conductivity, hnav tsis kam, corrosion kuj thiab oxidation kuj ntawm magnesium alloy
Kev ua ntawm magnesium alloy qhov chaw
3. Magnesium alloy conversion txheej kho:
Stable insoluble compound zaj duab xis yog tsim nyob rau saum npoo ntawm magnesium alloy
①. Tshuaj hloov dua siab tshiab ntawm magnesium alloy: kev ua haujlwm yooj yim thiab tus nqi qis, tab sis cov yeeb yaj kiab tiv thaiv tsim yog nkig thiab ntxeem tau, thiab tsis tuaj yeem siv los ua cov yeeb yaj kiab ntev tiv thaiv corrosion ntawm magnesium alloy.
②. Magnesium alloy anodic micro arc oxidation: anodic oxidation siv electrolysis los ua oxide zaj duab xis rau saum npoo ntawm magnesium alloy; Micro arc oxidation lov los ntawm anodic oxidation technology, uas muaj ob qho tib si kev ua tau zoo ntawm anodic oxide zaj duab xis thiab qhov zoo ntawm ceramic txheej. Txawm li cas los xij, thev naus laus zis tsis paub tab txaus thiab xav tau kev tshawb fawb ntxiv.
③. Magnesium alloy E txheej: los ntawm txoj kev no, magnesium alloy nto tuaj yeem tau txais kev tiv thaiv corrosion zoo
4. Magnesium alloy txheej:
① Thermal txau ntawm magnesium alloy: cov ntaub ntawv txau yog rhuab thiab yaj los ntawm nplaim taws, laser, arc lossis ntshav thiab lwm qhov chaw tshav kub, thiab qhov chaw ntawm magnesium alloy yog txau ntawm qee qhov ceev los tsim cov txheej txheem tiv thaiv.
② Organic txheej thiab hmoov txheej ntawm magnesium alloy: cov organic txheej yog nyias thiab yooj yim poob; Hmoov txheej yog qhov nyuaj kom tau txais qee qhov zais zais.
③. Vapor Deposition ntawm Magnesium Alloys: Txhim kho Corrosion Resistance ntawm Magnesium Alloys
5. Kev hloov kho deg ntawm magnesium alloy:
Nws tau muab faib ua magnesium alloy diffusion thiab magnesium alloy ion implantation
6. Siab zog nqaj kho ntawm magnesium alloy:
Qhov saum npoo ntawm magnesium alloy yog rhuab sai heev los ntawm laser, plasma, thiab lwm yam kom tau cov txheej txheej ntawm quenching, sai solidification los yog cladding.
