Nrog kev nce qib sai ntawm kev kawm tshawb fawb thiab thev naus laus zis, thermal txau tau hloov kho rau hauv cov txheej txheem ntau, qib siab-tech. Nws tsis yog tsuas yog cov ceg tseem ceeb ntawm cov txheej txheem Engineering saum nplaim, tab sis kuj tau dhau los ua cov txheej txheem tseem ceeb rau cov khoom siv tau ncaj qha thiab cov khoom lag luam nrog cov khoom tshwj xeeb thiab cov duab. Thermal txau, raws li ib qho kev sib xyaw ua hluav taws xob, siv ntau qhov chaw ua cua sov kom sov cov ntaub ntawv-alloys, yas, cerasites, thiab lawv lub xeev lossis melted xeev. Cov ntaub ntawv no yog tom qab ntawd atomized ntawm kev kub ceev los ntawm ib tug "nplua-particet rau hauv qhov chaw ua haujlwm ua ntej ua haujlwm, sib sau ua kom nruj heev rau cov txheej txheem. Yog hais tias feem ntawm cov txheej txau tau rov qab thaum lossis tom qab cov txau txheej txheem ua kom tiav cov yam ntxwv me me, cov ntaub ntawv no lossis cov txheej remelted.
Ntshav txau, ib hom cua sov txau thev naus laus zis, ua haujlwm los ntawm kev qhia cov hmoov hlau lossis tsis sib xws plasma arc nplaim hluav taws, muab cua sov lawv mus rau lub xeev me me. Cov hmoov yog tom qab ntawd ntiab tawm ntawm kev kub ceev raws cov ntshav hluav taws xob mus rau cov txheej txheem ua ntej workpiece, sib sau nrog cov khoom tshwj xeeb. Thaum lub sijhawm plasma txau, cov nplaim taws siab thiab cov nplaim taws kub ua rau muaj ntau cov hmoov ntawm cov khoom hmoov uas tsis muaj ntau yam kub thiab txias, ua rau muaj cov ntau yam khoom. Lub tsho tiv no du thiab tiaj tus, nrog cov ntsiab lus tsis zoo (nce mus txog 60-70 n / ololity muaj zog (thiab tsis muaj kev hloov ntawm cov qauv lev.
Hauv orthopedics thiab kev kho hniav, hydroxyapatite (ha) coatsings tsuag mus rau Ti6al4V alloy qhov chaw tau txiav txim siab muaj cov khoom siv bioimplant. Cov khoom siv no sib txuas nrog biocompatibility zoo heev nrog cov khoom siv neeg kho zoo. Kev sim kho mob tag nrho hip arthroplasty thiab kev cog hniav tau pom cov txiaj ntsig hydrowscle thov kom muaj peev xwm los tsim cov pob txha tshiab ntawm txheej txheej txheej txheej. Kev tshawb fawb ntawm Bioactivity ntawm calcium phosphate bioceramics thiab bioglass (bg) muaj tsawg dua 60% los ntawm huab hwm coj zoo tshaj plaws piv rau HA. Nyob rau hauv tib neeg lub cev kua, bioglass undergoes muaj cov txheej txheem biological, suav nrog cov khoom siv roj ntsha Txhawm rau txhim kho qhov biofactivity ntawm HA thiab ua kom muaj zog txaus, muaj ntau cov kws tshawb nrhiav tau ua kev tshawb fawb ntawm Ti6al4V alloy nto. Lub txiaj ntsig ua tiav ua tiav lub zog ua tau txaus rau kev cog lus. Txawm li cas los xij, cov kev tshawb fawb tom qab hauv tib neeg lub cev kua dej tau qhia tias kev sib raug zoo ntawm Hydroxyapatite Txheej ntawm Ti6al4V alloy qhov chaw poob qis los ntawm 40%. BG txheej txheej tseem ruaj khov nyob rau hauv qis avity ib puag ncig ib puag ncig, tab sis kuj tseem tau ntsib 40% poob hauv kev sib txuas lus siab. Hauv kev sib piv, ha / bg hybrid txheej txheej outsperformed ob qho tib ha thiab bg cov tshuaj pleev hauv qab huab cua noo.
Ntshav txau thev naus laus zis muaj cov txiaj ntsig zoo hauv Biosurface kev hloov kho ntawm titanium alloy dag cov ntaub ntawv sib koom tes. Firstly, cov hnav-resistant coating zoo pab txhim kho cov khoom saum npoo ntawm titanium alloys. Thib ob, biolompibrass Ha thiab bioglass txheej ntau txhim kho qhov bioactivity ntawm cov khoom. Txawm li cas los xij, kawm yuav ua li cas siv cov ntshav txau siv cov khoom lag luam zoo thaum cov khoom tsis txaus ntseeg ntawm cov khoom yog qhov tseem muaj txoj haujlwm nyuaj heev.
Lub tuam txhab khav ua cov khoom lag luam hauv tsev titanium ua ntau lawm, nrog rau:
German-imported precision titanium raj ntau lawm kab (txhua xyoo muaj peev xwm ntau lawm: 30,000 tons);
Japanese-technology technology tentanium ntawv ci rolling kab (thinnest rau 6μm);
Qoos motated titanium qws txuas ntxiv mus rau kab extrusion;
Ntse titanium phaj thiab sawb fining;
MES system ua noj digital tswj thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm, ua tiav cov khoom lag luam seem ntawm ± 0.01M.
