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 thiab titanium alloy daim hlau? Los ntawm cov tsos ib leeg, txawm tias nws yog sandblasted nto los yog alkaline acid-ntxuav nto, 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. Ntawm no' piav qhia luv luv ntawm qhov txawv:
1. Kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg
Peb tuaj yeem ua ntej txiav cov tshuaj lom neeg muaj pes tsawg leeg los ntawm kev soj ntsuam cov chaw tso cai. Lub impurity cov ntsiab lus ntawm kev lag luam ntshiab titanium tsis tshaj 0.1%, thiab titanium alloy phaj yuav muaj qhov sib txawv pom tseeb raws li qhov sib piv alloy.
2. Kev txheeb xyuas hardness
The hardness of a pure titanium plate is 1/2 times that of an ordinary steel plate. The hardness of industrial pure titanium is usually less than 120-290 Brinell hardness, the higher the purity. The hardness of the highest purity grade of industrial pure titanium is usually less than 120 (Brinell du), and the hardness of other industrial pure titanium is 200--295 (Brinell). The hardness of pure titanium castings is 200-220 (Brinell). The hardness value of titanium alloy in the annealed state is 32-38 (Rockwell, C calibration), which is equivalent to 298-349 Brinell hardness. The as-cast and titanium Ti-6AL-4V had a hardness of 320 (Brinell) and the low interstitial impurity Ti-6AL-4V casting had a hardness of 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. The elements that stabilize the α phase and increase the phase transition temperature are α stable elements, such as aluminum, carbon, oxygen, and nitrogen. Among them, aluminum is the main alloying element of titanium alloy, which has obvious effects on improving the normal and high-temperature strength of the alloy, reducing the specific gravity, and increasing the elastic modulus.
3. The elements that have little effect on the phase transition temperature are neutral elements, such as zirconium and tin.
3. With the help of professional equipment
Tam sim no cov spectrometers los yog 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 cov 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 cov ntaub ntawv kho mob titanium xws li cov khoom siv phaj rau pob qij txha, kho hniav, pob txha fixation pab kiag li lawm, thiab lwm yam. feem ntau yog cov ntshiab titanium daim hlau thiab titanium alloy daim hlau. Cov feem ntau yog gr2 ntshiab titanium daim hlau, thiab gr5 yog cov feem ntau titanium alloy phaj, uas ti-6al -4v belongs rau lub ntsiab muaj pes tsawg leeg ntawm gr5 titanium alloy phaj. Nyob rau hauv qhov tseeb kev kho mob-kev lag luam ntau lawm, tseem muaj kev pheej hmoo ntawm doping ntshiab titanium daim hlau thiab titanium alloy daim hlau, uas ncaj qha adversely cuam tshuam rau tom qab ntog txheej txheem thiab machining txheej txheem. 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 txheej txheej, ntom, thiab lwm yam khoom, tom qab sampling thiab calcination, ntshiab titanium phaj thiab titanium alloy phaj yuav txawv los ntawm kev soj ntsuam cov xim ntawm cov oxide zaj duab xis. ntawm tus 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. Tab sis peb ntseeg hais tias nyob rau hauv lub neej yav tom ntej, nrog rau kev vam meej ntawm cov txheej txheem ntau lawm, ib txoj kev yooj yim ntawm kev sib txawv ntawm ntshiab titanium daim hlau thiab titanium alloy daim hlau yuav twv yuav raug hu tshwm.
customized ntshiab titanium ntawv, tos ntsoov rau koj qhov kev sib tham!
