II. Txheej txheem ntau lawm
Cov txheej txheem ntawm kev ua Ta2.5W tantalum taum lossis pob yog qhov nyuaj heev. Nws koom nrog ntau cov kauj ruam pib los ntawm kev ua cov khoom siv raw kom huv si, muab lawv cov duab kawg. Cov thev naus laus zis tseem ceeb siv los ua Ta2.5W tantalum taum lossis cov pob tsom rau ib yam tseem ceeb: ua kom cov khoom sib xyaw ntawm cov hlau tsis sib xws uas cov npas zoo kawg nkaus puag ncig thiab tias Ta2.5W tantalum taum lossis pob ua haujlwm tas li. Qhov no yog qhov tseem ceeb rau Ta2.5W tantalum taum lossis pob kom zoo.
Kauj Ruam 1: Raw Material Purification & Alloy Preparation
* Tantalum Raw Material Refining: Siv cov tantalum ore thiab ua nws siv ib txoj kev hu ua ntub metallurgy.
* Tungsten Alloying: Peb siv hom hmoov hu ua tungsten.Qhov no tungsten hmoov yog 99.99% ntshiab. Peb sib tov cov hmoov tungsten no nrog lwm cov hmoov hu ua tantalum hmoov. Peb siv lub tshuab los sib tov ob cov hmoov no ua ke. Lub tshuab no ua kom paub tseeb tias cov tungsten thiab tantalum sib xyaw ua ke. Txoj kev no peb tuaj yeem paub tseeb tias Tungsten Alloying muaj cov ntsiab lus ntawm tungsten Alloying hauv nws. Tungsten Alloying sib tov yog 2.5%.

Txoj kev no peb tuaj yeem paub tseeb tias Tungsten Alloying muaj cov ntsiab lus ntawm tungsten Alloying hauv nws. Tungsten Alloying sib tov yog 2.5%.
Kauj Ruam 3: Sib Sau & Sintering
* Spherical Blank Forming yog txheej txheem uas lawv coj cov hmoov ntawm tungsten thiab tantalum thiab ua nws mus rau hauv spheres. Lawv siv ib hom kev nias uas siv lub siab los ntawm txhua sab kom paub tseeb tias cov hmoov ntim tau nruj thiab sib npaug. Qhov no siab yog tiag tiag siab tsawg kawg yog 200 MPa. Lub hom phiaj ntawm Spherical Blank Forming yog kom tau qhov ceev ntawm cov spheres kom siab npaum li qhov ua tau kom lawv muaj tsawg kawg yog 90 feem pua ntev raws li lawv tuaj yeem ua tau.
* Nqus Sintering yog txheej txheem uas qhov khoob yog rhuab nyob rau hauv lub cub tawg nrog cua me ntsis hauv. Lub cub tawg no zoo heev ntawm kev tshem tawm cua nws tuaj yeem ua rau huab cua siab tsawg. Qhov kub hauv qhov cub yog maj mam nce ntawm 1200 degrees mus rau 2000 degrees. Cov blanks yog khaws cia ntawm qhov kub thiab txias rau 4 mus rau 6 teev. Qhov no yuav pab tshem tawm cov qhov hauv qhov khoob thiab ua rau lawv ntom heev. Qhov ceev ntawm qhov khoob yuav ntau dua lossis sib npaug li 17 g / cm³. Cov txheej txheem Nqus Sintering kuj tseem pab tsim kom muaj kev sib xyaw ntawm Tantalum thiab Tungsten uas yog qhov peb xav tau. Qhov sib tov no hu ua Ta-W tov thiab nws ruaj khov heev.
Kauj Ruam 4: Precision Machining & Surface Treatment
* Sphericity Correction: Cov sintered blanks mus dhau ib txheej txheem. Lawv tau txais hauv av thiab polished nrog cov cuab yeej pob zeb diamond. Qhov no yuav pab kom qhov loj me nyob rau hauv qhov sib txawv me me ntawm ntxiv lossis rho tawm 0.005mm. Lub sphericity lossis npaum li cas puag ncig lawv kuj yog siab heev ntawm cuaj caum tsib feem pua lossis ntau dua. Qhov no yog qhov zoo txaus rau qhov chaw uas nkag mus rau hauv dav hlau thiab lub dav hlau uas yuav tsum tau muaj tseeb heev. Qhov kev kho qhov sphericity ntawm sintered blanks yog qhov tseem ceeb rau qhov no.
* Qhov saum npoo ntawm cov khoom tau txais ib txheej hu ua Surface Passivation. Cov txheej no yog ua los ntawm oxide zaj duab xis hu ua Ta₂O₅. Nws yog nyias, txog 5 mus rau 10 nanometers. Txhawm rau ua cov txheej txheem no, cov khoom siv yog rhuab hauv lub tshuab nqus tsev ntawm qhov kub thiab txias, ntawm 800 thiab 1000 degrees Celsius. Cov txheej txheem no hu ua lub tshuab nqus tsev annealing. Cov khoom tseem oxidized nyob rau hauv ib txoj kev tswj. Cov txheej tshwj xeeb no pab tiv thaiv cov khoom los ntawm kev puas tsuaj los ntawm corrosion. Nws tuaj yeem tiv taus acids tab sis nws tsis tiv taus hydrofluoric acid. Lub Surface Passivation txheej tseem ceeb heev rau kev tiv thaiv cov khoom ntawm corrosion.
Kauj Ruam 5: Kev Tshuaj Xyuas Zoo
Cheebtsam Kev Ntsuas: Spectral tsom xam (ib ASTM E415) txheeb xyuas W cov ntsiab lus thiab qib impurity, ua kom ntseeg tau raws li cov qauv.
* Thaum peb ua Kev Ntsuas Kev Ua Haujlwm ntawm cov khoom no peb tshawb xyuas ib qho tseem ceeb. Peb saib seb lawv nyuaj npaum li cas uas nyob nruab nrab ntawm 180 thiab 220HV. Peb kuj yuav tsum tau xyuas seb lawv ntom npaum li cas.Peb kuaj lawv muaj zog npaum li cas thaum lawv kub heev uas yuav tsum muaj tsawg kawg yog 150MPa thaum nws yog 1600 degree. Peb kuj ua-kev kuaj kev puas tsuaj, uas zoo li kev kuaj xyuas qhov tsis zoo ntawm ultrasonic kom pom tias muaj teeb meem hauv cov ntaub ntawv Kev Ntsuas Kev Ua Haujlwm.
