Cov txheej txheem ntau lawm
Ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm cov xim titanium qauv yog cov khoom siv raw. Qin Hao Cov Khoom Siv Tshiab Xaiv Qib 1 sponge titanium ua cov khoom siv raw kom ntseeg tau zoo los ntawm qhov chaw.
Kev kos duab (Modified)yog thaum titanium rods tau ua tiav rau hauv cov hlau ntawm qhov xav tau txoj kab uas hla los ntawm ntau qhov kev sib tw txias los yog kub dov. Cov txheej txheem no tsis tsuas yog hloov qhov loj me tab sis kuj txhim kho cov khoom siv zog thiab plasticity. Rau ultra- cov xov hlau zoo (xws li cov qis dua 3 hli), yuav tsum muaj 'ntau-theem kos duab + lubrication' txheej txheem los tiv thaiv kev tawg.
Nqus annealingyog siv los tshem tawm kev ua haujlwm hardening thiab rov qab cov khoom siv plasticity, ua kom yooj yim rau kev sib sau ntxiv.
Cov txheej txheem muaj xws li:
- Recrystallization annealing: rhuab mus rau 700-800℃los kho cov nplej thiab txhim kho ductility;
- Homogenization annealing: tshem tawm cov kev sib cais sib cais hauv lub ingot thiab txhim kho cov txheej txheem sib xws.
Picklingtshem tawm cov nplai oxide thiab cov kab mob uas ua rau ntawm titanium nto thaum ua haujlwm kub. Nws yog feem ntau ua nrog sib tov ntawm hydrofluoric acid thiab nitric acid rau tshuaj ntxuav. Tom qab pickling, qhov saum npoo tseem yuav tsum tau muab yaug thiab nruab nrab kom paub tseeb tias nws huv si thiab tiv thaiv qhov tsis xws luag hauv kev ua haujlwm tom qab.
Lub taub hau txias (los yog lub taub hau sov)kev sib sau siv cov tuag los nias titanium hlau rau hauv cov ntsia liaj qhov rooj blanks ntawm chav tsev kub los yog nyob rau hauv ib tug rhuab lub xeev.
Xovyog ua los ntawm dov los yog txiav
- Rolled threads: txias ua hauj lwm hardening yuav ua rau kom xov zog, zoo rau loj ntau lawm;
- Txiav threads: Siv rau qhov loj lossis tshwj xeeb- cov bolts, ntau meej tab sis tsis muaj txiaj ntsig.
Kev kho cua sovrau siab - lub zog bolts yuav tsum muaj quenching thiab tempering los txhim kho tag nrho cov neeg kho tshuab kev ua tau zoo.
- Tshuaj + Kev laus kev kho mob: Haum rau cov alloys xws li TC4, thawj zaug siab -kub tshuaj kho, tom qab ntawd qis- kub aging, precipitating nplua theem, uas tuaj yeem ua rau muaj zog ntau dua 30%.
Tom qabKev kho cua sov, koj yuav tsum nruj me ntsis tswj hardness, tensile zog, thiab tawm los - mus rau - tensile ratio kom paub tseeb tias lawv ua tau raws li 8.8 los yog 10.9 qib qauv.
Kev kho saum npootxhim kho corrosion kuj, hnav tsis kam, thiab zoo li zoo. Cov txheej txheem muaj xws li:
- Anodizing: Tsim cov txheej oxide tuab uas muab kev tiv thaiv corrosion thiab zoo nkauj, thiab tuaj yeem ua rau dyed;
- Micro-arc oxidation: Tsim cov txheej txheem ceramic (5μm), txo cov kev sib txhuam coefficient ntawm 0.8 mus rau 0.15, ua kom muaj zog qaug dab peg;
Sandblasting / Polishing: Txhim kho qhov smoothness, haum rau kev kho mob lossis siab - cov khoom siv kawg.
Kev davkev tswj kom zoorau kev soj ntsuam cov khoom tiav yog qhov tseem ceeb los xyuas kom meej qhov kev ntseeg siab ntawm titanium bolts. Cov khoom kuaj xyuas muaj xws li:
- Tshuaj ntsuam xyuas muaj pes tsawg leeg: Siv lub spectrometer kom paub meej tias cov ntsiab lus ntawm cov hlau alloy;
- Mechanical performance testing: Sampling for tensile, hardness, and impact tests;
- Kev ntsuam xyuas tsis muaj kev puas tsuaj: Siv kev ntsuas ultrasonic rau qhov tsis xws luag sab hauv thiab eddy tam sim no kuaj rau saum npoo tawg;
- Kev tshuaj xyuas qhov ntev thiab qhov pom: Ua kom ntseeg tau raws li cov qauv thoob ntiaj teb xws li GB/T, ISO, thiab AMS.
Qinhao Cov Khoom Siv Tshiab ua kom ntseeg tau qhov zoo tshaj plaws ntawm nws cov khoom ntawm txhua theem, los ntawm cov khoom siv raw mus rau cov khoom tiav, thiab txhawb nqa thib peb - kev tshuaj xyuas zoo. Cov neeg siv khoom kuj tuaj yeem hais qhia lub chaw kuaj xyuas. Yog tias koj muaj kev xav tau, koj tuaj yeem nug.
