Qhov sib txawv ntawm high-temperature alloys thiab titanium alloys
Nrog rau kev txhim kho tas mus li ntawm kev lag luam xws li aviation, aerospace, thiab chemical engineering, high-temperature alloys thiab titanium alloys, ob qho kev ua tau zoo alloys, tau txais kev pom zoo los ntawm tib neeg. Lawv muaj cov yam ntxwv ntawm kev ua tau zoo thiab ntau yam kev thov sib txawv. Yog li dab tsi yog qhov txawv ntawm high-temperature alloys thiab titanium alloys?
1.High kub alloy
Cov hlau kub kub xa mus rau cov alloys uas muaj cov khoom zoo xws li oxidation tsis kam, thermal qaug zog, creep tsis kam, thiab hnav tsis kam nyob rau hauv qhov kub thiab txias. Raws li cov sib txawv matrix ntsiab, high-temperature alloys yuav muab faib ua hlau-raws li, nickel raws li, thiab cobalt raws hom. Ntawm lawv, npib tsib xee raws li kub-kub alloys tau dhau los ua cov khoom siv dav tshaj plaws vim lawv qhov kev ua haujlwm kub kub zoo heev thiab cov khoom siv zoo tshaj plaws. Cov yam ntxwv ntawm kev ua haujlwm:
(1) Kev ua haujlwm kub zoo: Cov hlau kub kub muaj qhov ua haujlwm siab oxidation, thermal qaug zog, nkag tsis kam, thiab hnav tsis kam ntawm qhov kub thiab txias.
(2) Cov khoom siv zoo tshaj plaws: Cov hlau kub kub muaj lub zog siab, zoo toughness, thiab zoo tiv thaiv kev ntxhov siab corrosion tawg.
(3) Kev ua haujlwm zoo: Cov hlau kub kub tuaj yeem ua tiav los ntawm ntau txoj hauv kev, xws li casting, forging, dov, kos duab, thiab vuam.
2. Titanium alloy
titanium alloy yog ib qho alloy uas tsim los ntawm titanium thiab lwm yam ntxiv. Titanium alloys muaj cov cuab yeej zoo, kev tiv thaiv corrosion, thiab biocompatibility zoo, thiab tau dav siv hauv aviation, aerospace, tshuaj lom neeg, kev kho mob thiab lwm yam. Cov yam ntxwv ntawm kev ua haujlwm:
(1) Cov khoom siv zoo heev: Titanium alloys muaj lub zog siab, zoo toughness, thiab zoo corrosion kuj.
(2) Zoo corrosion kuj: Titanium alloy muaj corrosion kuj zoo heev nyob rau hauv seawater, ua rau nws lug siv nyob rau hauv lub marine engineering.
(3) Zoo biocompatibility: Titanium alloy muaj biocompatibility zoo thiab yog dav siv hauv kev kho mob, xws li cov pob qij txha, implanted scaffolds, thiab lwm yam.
3. Qhov sib txawv ntawm high-temperature alloys thiab titanium alloys
Cov alloys kub kub thiab titanium alloys yog ob qho tib si kev ua haujlwm siab, tab sis muaj qee qhov sib txawv ntawm lawv.
(1) Cov ntsiab lus sib txawv ntawm cov matrix: Cov hlau kub kub feem ntau siv cov khoom xws li npib tsib xee, cobalt, thiab hlau raws li matrix, thaum titanium alloys feem ntau yog tsim los ntawm titanium.
(2) Cov yam ntxwv ntawm kev ua haujlwm sib txawv: Cov yam ntxwv tseem ceeb ntawm cov khoom siv kub kub yog qhov ua tau zoo ntawm qhov kub thiab txias, haum rau qhov kub thiab txias ib puag ncig; Titanium alloys paub txog lawv cov khoom zoo heev thiab kev tiv thaiv corrosion.
(3) Cov ntawv thov sib txawv: Cov khoom siv kub kub yog siv rau hauv cov chaw kub kub xws li aviation thiab aerospace, thaum titanium alloys tau siv dav hauv aviation, aerospace, tshuaj, kho mob thiab lwm yam.
Muaj qee qhov sib txawv ntawm qhov kub-kub alloys thiab titanium alloys nyob rau hauv cov nqe lus ntawm matrix ntsiab, kev ua tau zoo, thiab daim ntawv thov teb. Nrog rau kev txhim kho thev naus laus zis, nws ntseeg tau tias ob lub alloys no yuav nrov zuj zus hauv lub neej niaj hnub.
