Thaum lub sij hawm ua thiab siv cov titanium daim hlau, discoloration feem ntau tshwm sim nyob rau saum npoo, uas tsis tsuas yog cuam tshuam cov tsos zoo tab sis kuj yuav txo tau lawv corrosion kuj thiab txhua yam khoom. Raws li cov ntaub ntawv tshawb fawb los ntawm Titanium House thiab kev coj ua hauv kev lag luam, tsab xov xwm no tau piav qhia txog cov txheej txheem kev daws teeb meem los daws cov teeb meem ntawm titanium phaj discoloration, muab ib txoj hauv kev siv rau kev lag luam.
Kev kho mob saum npoo av: tsim kev tiv thaiv kev tiv thaiv
Titanium phaj xim hloov feem ntau yog tshwm sim los ntawm kev puas tsuaj los yog kis kab mob ntawm cov oxide txheej. Los ntawm kev kho saum npoo, nws tsis kam hloov xim tuaj yeem txhim kho tau zoo:
1. Anodizing
Los ntawm electrolysis, ib tug tuab oxide zaj duab xis (thickness 1-}30 μm) yog tsim nyob rau saum npoo ntawm titanium phaj, zoo cais qhov nruab nrab ib puag ncig. Piv txwv li, kev kho mob -qib titanium alloy tom qab micro-arc oxidation kev kho mob, lub hardness ntawm lub saum npoo yog nce los ntawm 3 lub sij hawm, corrosion kuj yog txhim kho los ntawm 50%, thiab ib tug xim oxide txheej yog tsim, uas combines ob qho tib si zoo nkauj thiab kev tiv thaiv kev ua haujlwm.
2. Txheej txau
Siv plasma spraying technology los tso oxide aluminium thiab zirconia ceramic txheej, nws tuaj yeem tiv taus qhov kub ntawm 1200℃thiab haum rau qhov chaw huab cua xws li dav hlau cav hniav. Kev sim cov ntaub ntawv qhia tau hais tias lub coated titanium phaj muaj lub sij hawm ntev corrosion kuj ntawm ntau tshaj 2000 teev nyob rau hauv kev ntsuam xyuas ntsev tsuag.
3. Kev tiv thaiv electroplating
Nickel-raws li lossis chromium-raws li cov txheej txheem electroplating tuaj yeem ua rau qhov tawv tawv ntawm titanium phaj (HV800-1200) thiab txo cov kev sib txhuam coefficient. Rau titanium daim hlau siv nyob rau hauv lub tsheb txuas rods tom qab electroplating kev kho mob, hnav tsis kam yog nce los ntawm 40% thiab qhov kev pheej hmoo ntawm kev hloov xim yog txo los ntawm 70%.
Txheej txheem tswj: Precise parameter tswj
Lub thermal stress thiab mechanical puas thaum lub sij hawm ua yog lub ntsiab ua rau kev hloov xim. Los ntawm cov txheej txheem optimization, kev tswj tau tuaj yeem ua tiav:
1. Dynamic kub tswj
Thaum txiav titanium daim hlau, qhov kub ntawm cov cuab yeej txiav yuav tsum tau tswj hauv qab 400 degree. Los ntawm kev siv qis-kub txiav cov kua (xws li dej-raws li emulsion) ua ke nrog cov khoom siv tawv tawv-coated txiav, qhov kub ntawm qhov chaw txiav tuaj yeem raug txo los ntawm 30%, thiab qhov roughness Ra tus nqi tuaj yeem ruaj khov nyob rau hauv 0.8μm, txo cov thermal oxidation xim hloov.
2. Cov qauv kev ntxhov siab tso tawm
Los ntawm kev txheeb xyuas cov ntsiab lus finite txhawm rau txhim kho qhov sib txuas ntawm cov titanium daim hlau, cov txheej txheem segmented annealing (500℃/ 2h) tau txais yuav los tshem tawm cov kev ntxhov siab. Cov kev sim qhia tau hais tias tom qab kev ua kom zoo, qhov deformation ntawm titanium phaj ntawm 350℃yog txo los ntawm 65%, thiab qhov chaw hloov xim yog txo los ntawm 80%.
3. High-kev ua haujlwm ceev
Siv tsib -axis联动high-ceev milling (rotational ceev 12000r/min, pub tus nqi 0.1mm/r), lub sij hawm ua yuav luv luv los ntawm 40%, thiab cov thermal tsub zuj zuj nyhuv yuav txo tau. Cov ntaub ntawv kawm ntawm kev ua haujlwm hauv aerospace qhia tau hais tias cov txheej txheem siab - txo cov xim hloov pauv ntawm 15% mus rau qis dua 2%.
Ib puag ncig thiab kev tiv thaiv System: Tag nrho -cycle Management
Los ntawm kev khaws cia mus rau theem kev siv, ib qho kev tiv thaiv kev tiv thaiv yuav tsum tau tsim:
1. Environmental Parameter Control
Qhov kub thiab av noo ntawm lub warehouse cia yuav tsum khaws cia ntawm 25 ° ± 5 ° C, RH 40% -60%, thiab nruab nrog lub tshuab dehumidifier thiab huab cua pom. Kev coj ua ntawm cov chaw tsim khoom siv tshuaj lom neeg pom tau hais tias kev tswj hwm ib puag ncig tuaj yeem txo cov xim hloov pauv ntawm titanium daim hlau thaum khaws cia los ntawm 8% mus rau 0.5%.
2. Tshwj xeeb ntim tsim
Qhwv cov titanium daim hlau nrog VCI roj-theem tiv thaiv- xeb zaj duab xis thiab muab nws nrog cov desiccant kaw ntim los tsim ib txheej tiv thaiv roj inert. Cov txheej txheem ntim tau raug txheeb xyuas los ntawm ASTM B117 ntsev tshuaj tsuag, thiab nws txuas ntxiv lub sijhawm corrosion ntawm titanium daim hlau mus txog 1500 teev.
3. Siv tau scene
Rau siab - qhov kub thiab txias ntawm kev sib txhuam ib puag ncig (xws li hauv cov tshuab dav hlau), raug coated nrog MoS₂, titanium alloy hniav ntawm ib hom cav, tuaj yeem txo qhov sib txhuam coefficient, nce qhov kub thiab txias, thiab ncua kev pab cuam lub neej los ntawm 2.3 zaug.
Kev Tswjhwm Zoo: Cov ntaub ntawv-tsim kev txhim kho
Tsim kom muaj tag nrho - txheej txheem traceability los ntawm raw khoom mus rau cov khoom tiav:
1. Kev Tshawb Nrhiav Online Technology
Siv Laser Induced Breakdown Spectroscopy (LIBS) los saib xyuas cov ntsiab lus ntawm titanium daim hlau hauv lub sijhawm. Lub tswb tshwm sim thaum qhov sib txawv tshaj 0.5%. Tom qab siv cov thev naus laus zis no rau kev kho mob cog cov kab ntau lawm, cov khoom tsim nyog tau nce mus rau 99.8%.
2. Tsis yog- Cov Qauv Ntsuas Kev Ntsuas
Ua raws li kev ntsuam xyuas penetrant raws li ASTM E165 tus qauv, uas tuaj yeem txheeb xyuas qhov tawg ntawm qhov me me li 0.01mm. Kev lag luam aviation yuav tsum tau kuaj pom qhov tsis xws luag ntawm 100% rau titanium daim hlau kom muaj kev nyab xeeb ntawm cov qauv.
3. Kev Ntsuam Xyuas Tus Neeg Siv Khoom
Tsim kom muaj kev ntsuam xyuas tus neeg muag khoom uas muaj 20 qhov ntsuas xws li cov txheej txheem melting, purity tswj, thiab muaj peev xwm kho qhov chaw. Tom qab qee lub tuam txhab tsim tsheb tau siv cov txheej txheem no los tshuaj xyuas cov neeg siv khoom, tus nqi ntawm titanium phaj tuaj yeem hloov pauv tau los ntawm 3.2% mus rau 0.1%.
