ntshiab molybdenum phaj nrog qhov molybdenum machined ib feem
Molybdenum phaj, tseem hu ua molybdenum phaj, yog ib lub tiaj tus ntawm molybdenum hlau feem ntau siv nyob rau hauv ntau yam kev siv vim nws cov khoom zoo heev. Molybdenum daim hlau paub txog lawv qhov siab melting point, zoo heev thermal conductivity thiab corrosion kuj, ua rau lawv haum rau siv nyob rau hauv kub kub thiab corrosive tshuaj ib puag ncig.
Cov nplooj ntawv no tuaj yeem siv los tsim cov khoom cua sov, hluav taws xob tiv thaiv, sputtering lub hom phiaj thiab lwm yam khoom tshwj xeeb. Tsis tas li ntawd, cov nplooj ntawv molybdenum feem ntau ua tiav los tsim cov khoom tshwj xeeb lossis cov khoom siv rau kev lag luam xws li aerospace, tiv thaiv thiab hluav taws xob.
Zuag qhia tag nrho, cov nplooj ntawv molybdenum muaj nuj nqis rau lawv cov kav ntev, tiv thaiv tshav kub, thiab muaj peev xwm tiv taus cov xwm txheej hnyav, ua rau lawv yog cov khoom tseem ceeb hauv ntau yam kev lag luam thiab kev tsim khoom.
Cov lus qhia tshwj xeeb rau molybdenum machining yuav txawv raws li cov ntawv thov tshwj xeeb thiab cov cai. Txawm li cas los xij, qee qhov kev txiav txim siab dav dav rau kev ua molybdenum suav nrog:
1. Cov cuab yeej txiav: Vim lub hardness ntawm molybdenum, high-speed steel (HSS) los yog carbide tej cuab yeej feem ntau yog siv rau tshuab molybdenum. Pob zeb diamond cov cuab yeej kuj siv rau precision machining.
2. Txiav ceev thiab pub: Piv nrog rau lwm yam hlau, molybdenum yuav tsum tau txiav ceev thiab pub ntau dua. Qhov no yog vim nws lub zog siab thiab ua haujlwm rau deformation.
3. Lubrication: lubrication kom zoo yog qhov tseem ceeb thaum lub sij hawm molybdenum machining kom txo tau kev sib txhuam thiab kub tsim. Feem ntau yog siv cov roj av los yog roj-raws li lubricants.
4. Ua kom txias: Cov txheej txheem ua kom txias zoo, xws li siv cov cua txias lossis cov cua compressed, yog ib qho tseem ceeb rau dissipate lub tshav kub generated thaum machining.
5. Cov cuab yeej geometry: Lub geometry ntawm cov cuab yeej txiav, nrog rau cov kab rake thiab nyem, yuav tsum tau ua kom zoo rau molybdenum machining kom ntseeg tau tias cov khoom siv tau zoo thiab lub neej ntawm lub cuab yeej.
6. Nto tiav: Molybdenum ua feem ntau yuav tsum muaj txheej txheem tom qab ua tiav kom tiav qhov yuav tsum tau ua tiav, vim tias molybdenum nquag ua haujlwm hardening thaum ua.
7. Kev ceev faj txog kev nyab xeeb: kev ua cov molybdenum tuaj yeem tsim cov plua plav lossis cov khoom zoo, yog li kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua, suav nrog kev siv cov khoom tiv thaiv tus kheej thiab cov plua plav pov tseg.
Nws yog ib qho tsim nyog sau cia tias cov txheej txheem tshwj xeeb yuav txawv nyob ntawm qib thiab cov duab ntawm molybdenum ua tiav thiab cov khoom xav tau kawg.
Ntshiab molybdenum tsis suav hais tias nkig. Nws yog cov hlau refractory paub txog nws lub zog tensile siab, zoo heev thermal conductivity thiab corrosion kuj. Qhov tseeb, molybdenum nthuav tawm kev sib xyaw ua ke ntawm lub zog thiab ductility, ua rau nws tsim nyog rau ntau yam kev siv, nrog rau qhov kub thiab txias ib puag ncig thiab cov khoom siv hauv ntau yam kev lag luam.
Txawm li cas los xij, qhov brittleness ntawm molybdenum tuaj yeem cuam tshuam los ntawm cov khoom xws li impurities, grain loj thiab cov txheej txheem ua. Hauv qee cov ntaub ntawv alloy lossis nyob rau hauv qee yam mob, molybdenum tuaj yeem pom muaj qib ntawm brittleness. Yog li ntawd, lub brittleness ntawm molybdenum nyob ntawm qhov tshwj xeeb alloy, kev ua thiab ib puag ncig yam.
Zuag qhia tag nrho, ntshiab molybdenum paub txog nws lub zog thiab ductility thiab yog siv dav hauv cov ntawv thov uas xav tau cov khoom no.
