Vim li cas cov txheej txheem tseem ceeb
Titanium bolts yog siv rau qhov tsis ua hauj lwm tsis yog ib qho kev xaiv - dav hlau cav, airframes, sib sib zog nqus- cov khoom siv dej hiav txwv, cov khoom siv kho mob. Lub dav hlau ua lag luam C919 ib leeg siv kwv yees li200,000 titanium fasteners. Txhua tus yuav tsum ua kom tau raws li cov qauv tsim nyog rau chemistry, lub zog, qhov tseeb qhov tseeb, thiab qhov tseeb ntawm qhov chaw.
Txoj kev tsim khoom los ntawm raw titanium ingot mus rau cov ntawv pov thawj bolt yog ntev, meej, thiab tsis zam txim.
Cuaj theem
1. Raw Khoom: Triple -Melted Titanium Ingot
Txhua yam pib nrogNqus Arc Remelting (VAR). Titanium ingots feem ntau yog yajpeb zaugkom ua tiav qhov siab tshaj plaws tshuaj uniformity thiab tsawg kawg impurity cov ntsiab lus.
| Qib | Daim ntawv thov |
|---|---|
| TA 2(CP titanium) | Kev ua tshuaj lom neeg, kev kho mob - corrosion kuj tseem ceeb |
| TC 4(Ti-6Al-4V) | Aerospace - tso nyiaj rau95% + ntawm aerospace fastener ntim |
2. Hlau ua: Kos duab thiab Annealing
Lub ingot yog ua tiav rau hauv bar, ces kos los ntawm ntau qhov hla mus rau lub hom phiaj txoj kab uas hla. Rau cov hlau zoo (hauv qab 3 hli), amulti-theem annealing ntxiv rau lubricationtxheej txheem tiv thaiv kev tawg.
Nqus annealing raws li nram no kom tshem tawm ua hauj lwm hardening:
| Annealing hom | Lub hom phiaj |
|---|---|
| Recrystallization (700-800 degree) | Restores ductility los ntawm grain restructuring |
| Homogenization | Tshem tawm kev sib cais ntawm kev sib cais los ntawm casting |
3. Acid Pickling: Nto Tu
Ib lub hydrofluoric-nitric acid da dej tshem tawm oxide nplai thiab cov kab mob ntawm qhov chaw los ntawm kev ua haujlwm kub. Ua raws li cov dej yaug thiab nruab nrab - kom ntseeg tau qhov chaw huv si rau kev sib sau ua ke.
4. Lub taub hau txias los yog sov: Hloov qhov khoob
Cov hlau yog tsim rau hauv ib lub bolt dawb paug siv precision tuag:
| Txoj kev | Siv Rau |
|---|---|
| Txias taub hau | Beta- hom alloys (TB2, TB5, Ti-45Nb) nrog rau chav tsev kub zoo ductility |
| Lub taub hau sov(650-800 degree) | TC4 thiab lwm yam + alloys - txo deformation kuj, tiv thaiv kev tawg |
5. Xov Tsim: Rolling vs. Txiav
| Txoj kev | Qhov zoo |
|---|---|
| Xov dov | Txias- ua hauj lwm hardens cov xov - ntau zog, npaum rau siab - ntim ntau lawm |
| Xov txiav | Ntau dua qhov tseeb rau qhov loj lossis tsis yog - tus qauv bolts - qis dua |
6. Kev kho cua sov: Kev daws + Kev laus
Siab - lub zog bolts tau dhau losdaws kev kho mob raws li kev laus:
- High -kub tshuaj dissolves alloying ntsiab rau hauv matrix
- Tsawg-kub aging precipitates fine -theem particles
- Qhov tshwm sim:lub zog nce ntawm 30% +
Tom qab-Kev kuaj xyuas kev kho mob: hardness, tensile lub zog, thiab qhov sib piv yuav tsum ua rawsQib 8.8 lossis 10.9qauv.
7. Kev kho deg: kev tiv thaiv thiab ua haujlwm
| Kev kho mob | Qhov Nws Ua Tau |
|---|---|
| Anodization | Dense oxide zaj duab xis - tiv thaiv corrosion + xaiv xim |
| Micro{0}}Arc oxidation | ~5μm ceramic txheej - kev sib txhuam coefficient poob los ntawm0.8-0.15 Nws, tiv thaiv galling |
| Pob zeb blasting / polishing | Txhim kho qhov chaw tiav rau kev kho mob lossis cov neeg siv khoom zoo |
8. Kev Tshuaj Xyuas Zoo: Lub Rooj Zaum Kawg
Cov hlau yog tsim rau hauv ib lub bolt dawb paug siv precision tuag:
|
Kuaj |
Txoj kev |
|---|---|
| Tshuaj muaj pes tsawg leeg | Kev tsom xam Spectroscopic |
| Mechanical zog | Tensile, hardness, cuam tshuam kuaj |
| Internal tsis xws luag | Kev kuaj ultrasonic |
| Nto tawg | Eddy tam sim no soj ntsuam |
| Dimensional raug | Kev pov thawj tiv thaiv GB / T, ISO, AMS cov qauv |
9. Daim ntawv thov
Titanium bolts yog tam sim no tus qauv hauv:
- aircraft Lub foob npas C919 sau npe hauv qab no- ~ 200,000 titanium fasteners ib airframe
- Deep- hiav txwv submersibles- kev sib txuas ntawm lub siab
- Kev kho mob implants- pob txha screws thiab phais kho tshuab
- Cov khoom siv tshuaj thiab marine- corrosion- cov pob qij txha tseem ceeb
Cov Khoom Siv Hauv Tsev: Qhov Peb Tuaj Hauv
Qhov zoo ntawm titanium bolt tiav yog ncaj qha txiav txim siab los ntawm qhov zoo ntawm cov khoom pib - titanium bar lossis xaim los ntawm nws tsim. Chemistry sib xws, microstructure uniformity, thiab qhov tseeb qhov tseeb ntawm cov khoom nyoos tag nrho propagated los ntawm txhua theem tom ntej tsim.
