Qhov txawv ntawm Ntshiab Titanium Phaj thiab Titanium Alloy Phaj
Ntau tus neeg yuav ntsib teeb meem tib yam thaum xaiv cov khoom siv titanium, uas yog, lawv txhua tus yog titanium. Dab tsi yog qhov txawv ntawm cov ntshiab titanium daim hlau thiab titanium alloy daim hlau? Los ntawm qhov tsos ib leeg, txawm tias nws yog sandblasted nto los yog alkaline acid ntxuav los yog polished nto, feem ntau cov neeg tsis tuaj yeem qhia qhov txawv. Yog tias koj xav ua kom muaj qhov sib txawv tiag tiag, koj xav tau kev tshuaj xyuas tob dua. Nov yog ib qho kev piav qhia luv luv ntawm qhov txawv:
1. Kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg
Peb tuaj yeem ua ntej txiav ib feem rau kev tshuaj xyuas tshuaj muaj pes tsawg leeg los ntawm cov chaw kuaj pom muaj cai. Lub impurity cov ntsiab lus ntawm kev lag luam ntshiab titanium tsis tshaj 0.1 feem pua , thiab cov titanium alloy phaj yuav muaj qhov sib txawv raws li qhov sib piv alloy.
2. Kev txheeb xyuas hardness
Lub hardness ntawm ntshiab titanium phaj yog 1/2 npaug ntawm zoo tib yam steel phaj. Lub hardness ntawm industrial ntshiab titanium feem ntau yog tsawg dua 120-290 Brinell hardness, qhov siab dua qhov purity, qhov ze ntawm Brinell hardness yog 120 Brinell. Lub hardness ntawm qib siab tshaj plaws purity ntawm industrial ntshiab titanium feem ntau yog tsawg dua 120 (Brinell du), thiab hardness ntawm lwm yam muaj ntshiab titanium yog 200--295 (Brinell). Lub hardness ntawm ntshiab titanium castings yog 200-220 (Brinell). Tus nqi hardness ntawm titanium alloy nyob rau hauv lub xeev annealed yog 32-38 (Rockwell, C calibration), uas yog sib npaug rau 298-349 Brinell hardness. Raws li-cam khwb cia thiab titanium Ti-6AL-4V muaj hardness ntawm 320 (Brinell) thiab qis interstitial impurity Ti-6AL-4V casting muaj hardness ntawm 310 (Brinell).
Lub hardness ntawm titanium alloy phaj yog nyob ib ncig ntawm 250 ~ 350HV, thiab cov ntsiab lus alloy ntawm ta2 titanium alloy phaj tuaj yeem muab faib ua peb pawg raws li lawv cov kev cuam tshuam ntawm theem hloov pauv kub:
1. Cov ntsiab lus stabilize cov theem thiab nce qib hloov pauv kub yog cov khoom ruaj khov, xws li txhuas, carbon, oxygen thiab nitrogen. Ntawm lawv, aluminium yog lub ntsiab alloying ntawm titanium alloy, uas muaj cov txiaj ntsig pom tseeb ntawm kev txhim kho qhov qub thiab kub siab zog ntawm cov hlau, txo qhov tshwj xeeb lub ntiajteb txawj nqus thiab nce elastic modulus.
2. Cov ntsiab lus ruaj khov rau theem thiab txo cov theem hloov pauv kub yog cov khoom ruaj khov, uas tuaj yeem muab faib ua ob hom: isomorphous thiab eutectoid. Cov khoom siv titanium alloys, yav tas los muaj xws li molybdenum, niobium, vanadium, thiab lwm yam .; Cov yav tas muaj xws li chromium, manganese, tooj liab, hlau, silicon, thiab lwm yam.
3. Cov ntsiab lus uas tsis tshua muaj kev cuam tshuam rau theem kev hloov pauv kub yog cov khoom nruab nrab, xws li zirconium thiab tin.
3. Nrog kev pab los ntawm cov cuab yeej tshaj lij
Tam sim no cov spectrometers lossis X-ray fluorescence spectrometers thiab cov khoom siv hluav taws xob sib piv kuj tseem tuaj yeem paub qhov txawv ntawm titanium daim hlau los ntawm titanium alloy phaj.
Tag nrho cov nyob rau hauv tag nrho cov, txij li thaum ntshiab titanium daim hlau thiab titanium alloy daim hlau muaj zoo heev tshav kub tsis kam, toughness, plasticity, lub zog, weldability, formability, corrosion kuj thiab biocompatibility, tam sim no kev kho mob cov ntaub ntawv titanium xws li dag cov ntaub ntawv phaj implanted nyob rau hauv cov pob qij txha, kho hniav implants. , pob txha fixation li, thiab lwm yam. feem ntau yog cov ntshiab titanium daim hlau thiab titanium alloy daim hlau, ntawm cov uas ta4 ntshiab titanium phaj yog feem ntau, tc4 yog cov feem ntau titanium alloy phaj, uas ti-6al {{3 }}v belongs rau lub ntsiab muaj pes tsawg leeg ntawm tc4 titanium alloy phaj. Hauv kev tsim kho kev lag luam tiag tiag, tseem muaj kev pheej hmoo ntawm doping ntshiab titanium phaj thiab titanium alloy phaj, uas ncaj qha cuam tshuam rau cov txheej txheem tom qab kev kho deg thiab cov txheej txheem machining. Txij li thaum tsis muaj qhov sib txawv tseem ceeb ntawm cov ntshiab titanium phaj thiab titanium alloy phaj nyob rau hauv cov nqe lus ntawm sab nrauv, ntom thiab lwm yam khoom, tom qab kuaj thiab calcination, ntshiab titanium phaj thiab titanium alloy phaj tuaj yeem paub qhov txawv los ntawm kev saib xyuas cov xim ntawm cov oxide zaj duab xis. qauv nrog qhov muag liab qab. Txawm li cas los xij, siv txoj kev no kom paub qhov txawv yog feem ntau ua haujlwm hnyav thiab qeeb, nrog kev ntseeg tsis zoo, thiab yuav tsum muaj kev txawj ntse heev. Cov cuab yeej siv tau los paub qhov txawv ntawm cov titanium thiab titanium alloys, thiab spectrometers / thermoelectric comparators / x-ray fluorescence spectrometers kuj tseem siv tau los paub qhov txawv cov titanium daim hlau thiab titanium alloy daim hlau, tab sis feem ntau ntawm cov cuab yeej no kim kim thiab nyob hauv qhov chaw. . Loj thiab tsis yooj yim rau nqa thiab txav mus los.
