Hmoov metallurgy, raws li cov txheej txheem tseem ceeb hauv kev tsim khoom, yog dav siv hauv kev lag luam xws li tsheb, aerospace, thiab hluav taws xob vim nws qhov zoo xws li kev siv cov khoom siv siab thiab ze rau -net-puab txoj kev. Kev ua haujlwm ruaj khov thiab kev ntseeg tau ntawm nws cov khoom siv tau zoo nyob ntawm qhov kev qhia tshwj xeeb. Cov kev qhia tshwj xeeb tsis yog tsuas yog kev txwv ntawm cov txheej txheem tsim khoom tab sis kuj tseem yog qhov tseem ceeb ntawm kev sib txuas ntawm kev tsim, kev tsim khoom, thiab kev siv, ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom sib tw.
Los ntawm kev tswj cov khoom raw mus rau cov khoom tiav, cov kev qhia tshwj xeeb npog tag nrho cov theem tseem ceeb ntawm cov txheej txheem. Hais txog cov khoom siv raw, cov tshuaj muaj pes tsawg leeg, qhov loj me me, thiab cov ntsuas ntws ntawm cov hmoov hlau yuav tsum tau qhia meej meej -piv txwv li, cov ntsiab lus oxygen ntawm hlau-raws li cov hmoov yuav tsum nruj me ntsis kom tsis txhob muaj qhov tsis xws luag thaum lub sij hawm sintering; particle loj tis ncaj qha cuam tshuam qhov ceev ceev thiab sintering shrinkage tus nqi, yuav tsum tau batch sib xws kuaj siv cov khoom xws li laser particle loj analyzers. Nyob rau hauv txoj kev tsim, nias siab, tuav lub sij hawm, thiab pwm precision yog nyob rau hauv qhov yuav tsum tau yuav tsum tau: tsis txaus siab yooj yim ua rau tsis tshua muaj zog ntsuab thiab tawg, thaum pwm tolerances tshaj qhov ntau yuav ua rau qhov sib txawv ntawm qhov sib txawv, cuam tshuam rau kev sib dhos tom ntej.
Sintering yog ib kauj ruam tseem ceeb hauv kev tsim cov hmoov metallurgy qhov chaw, thiab cov kev qhia tshwj xeeb yuav tsum tau nthuav dav sintering kub, tuav lub sijhawm, thiab huab cua tswj tsis tau. Kev siv tooj liab-raws li cov hmoov ua piv txwv, qhov kub siab sintering ntau dhau ua rau cov nplej coarsening thiab txo qis hardness, thaum qhov kub thiab txias heev ua rau densification nyuaj. Yog li ntawd, qhov ntsuas kub hloov pauv ntawm ± 10℃yuav tsum tau teeb tsa raws li cov khoom siv. Lub purity thiab ntws tus nqi ntawm cov cua tiv thaiv (xws li nitrogen los yog hydrogen) yuav tsum tau saib xyuas nyob rau hauv lub sij hawm ntawm kev tiv thaiv oxidation los yog carburization defects. Tsis tas li ntawd, kev tshaj tawm - cov kauj ruam ua haujlwm xws li kev kho cua sov thiab kev ntxiv dag zog rau saum npoo kuj xav tau cov txheej txheem kom meej meej kom paub meej tias cov ntsuas xws li hardness thiab hnav tsis kam ua tau raws li qhov xav tau ntawm daim ntawv thov scenario.
Nyob rau theem kev soj ntsuam zoo, cov kev qhia tshwj xeeb qhia cov qauv kev sim thiab kev lees paub rau cov khoom tseem ceeb xws li hardness, tensile zog, thiab metallographic qauv. Piv txwv li, porosity yog qhov taw qhia tseem ceeb rau kev ntsuas qhov ntom ntom thiab yuav tsum tau ua kom muaj nuj nqis siv cov duab tsom xam. Qhov kev txwv sab saud ntawm porosity txawv qhov sib txawv ntawm cov khoom siv rau ntau lub hom phiaj (xws li cov khoom siv thiab cov khoom siv lim). Nyob rau tib lub sijhawm, cov lus qhia tshwj xeeb hais txog batch traceability, yuav tsum tau khaws cov ntaub ntawv txheej txheem thiab cov ntaub ntawv xeem rau txhua batch ntawm cov khoom los muab lub hauv paus rau kev taug qab qhov teeb meem.
Raws li siab- cov khoom siv kawg xav tau qhov hnyav dua thiab muaj kev ntseeg siab dua, hmoov hlau metallurgy cov kev qhia tshwj xeeb tau hloov mus rau qhov tseeb dua thiab kev txawj ntse. Tsuas yog los ntawm kev ua raws li cov lus qhia no nruj me ntsis tuaj yeem hloov pauv kev lag luam los ntawm "kev tsim khoom" mus rau "kev tsim khoom zoo," muab siab - cov khoom ua tau zoo rau ntau yam.
