Nyob rau hauv cov tshuaj kho thiab aging theem ntawm alloy tshav kub kho, lubargon cua rauvplays lub luag haujlwm tseem ceeb ntawm kev nyab xeeb thiab kev tiv thaiv.
Tuav ib puag ncig tsis zoo ntawm qhov kub thiab txias, nws tiv thaiv cov hlau los ntawm kev ua pa nrog cov pa hauv huab cua, uas yuav cuam tshuam rau cov khoom siv kho tshuab kev ncaj ncees thiab qhov chaw zoo.
Tiv thaiv kom txhob muaj kab mob atmospheric
Kev tshem tawm ntawm siab -Tub kub Oxidation
Titanium alloys hnov mob nrog cov pa oxygen ntawm kev kho qhov kub ntawm 1050 degree.
Lub tshuab hluav taws xob argon hloov huab cua nrog siab -purity argon, tsim cov txheej txheem tiv thaiv uas tiv thaiv kev tsim ntawm brittle " -theem" lossis oxide nplai ntawm cov hlau nplaum.
Kev zam ntawm Hydrogen Embrittlement
Titanium muaj kev sib raug zoo rau hydrogen, uas tuaj yeem ua rau ua tsis tiav ntxov thaum muaj kev ntxhov siab. Lub inert argon ib puag ncig xyuas kom meej tias hydrogen tsis absorbed thaum lub sij hawm cua sov, yog li khaws cia lub alloy lub ductility thiab puas toughness.
Thermal Optimization thiab Stress Relief
Precise Microstructure Control
Lub tshuab hluav taws xob tso cai rau kev tswj xyuas qhov kub thiab txias thaum lub sijhawm kho thiab cov txheej txheem kev laus tom ntej.
Qhov kev txiav txim siab no yog qhov tseem ceeb rau kev tswj cov theem kev hloov pauv, kom ntseeg tau tias qhov kawg microstructure ua tau raws li cov kev cai tshwj xeeb ntawm biomedical lossis industrial applications.
Kev txo qis ntawm kev ntxhov siab
Cast Cheebtsam, tshwj xeeb tshaj yog, feem ntau muaj qhov tseem ceeb hauv kev ntxhov siab. Kev tswj cov cua sov thiab cua txias nyob rau hauv lub cub tawg argon pab kom homogenize cov khoom, zoo txo cov residual stresses thiab txhim kho qhov seem stability.
Argon Atmosphere vs. Nqus Ib puag ncig
Thaum lub qhov cub argon muab kev tiv thaiv zoo heev thaum kho cua sov, nws txawv ntawm lub tshuab nqus tsev vacuum arc siv nyob rau hauv lub melting theem.
Lub tshuab nqus tsev ib puag ncig yog qhov zoo tshaj plaws hauv kev tshem tawm cov pa roj, tab sis rau kev kho cov txheej txheem kev kho mob thiab kev laus lub voj voog uas muaj kev tiv thaiv saum npoo yog qhov tseem ceeb tshaj li kev tshem tawm roj, qhov cub argon feem ntau raug nqi ntau dua - siv tau thiab siv tau.
Kev txwv ntawm Inert Gas Purity
Qhov ua tau zoo ntawm lub cub tawg yog nyob ntawm qhov purity ntawm argon roj. Txawm tias cov dej noo lossis cov pa oxygen hauv cov khoom siv argon tuaj yeem ua rau muaj kev sib kis tsis zoo, yuav tsum tau saib xyuas nruj ntawm cov pa xa tawm.
Kev sib piv nrog Preheating Methods
Tsis zoo li muffle furnaces siv rau qis -kub preheating (kwv yees li 600 degree), lub argon rauv yog tsim tshwj xeeb rau cov huab cua kub uas yuav tsum tau rau theem transformations. Yog hais tias lub alloy yog rhuab nyob rau hauv ib tug standard muffle rauv ntawm 1050 degree, kev puas tsuaj oxidation yuav tshwm sim vim tsis muaj ib tug inert cua.
