GR2 Cladding Surface Ntawm Titanium Hlau Composite Phaj

1.Blees paub

Nyob rau hauv xyoo tas los no, kev kho saum npoo ntawm titanium steel composite daim hlau tau tsom mus rau kev sib tsoo ntawm cov hlau substrate, thaum muaj ob peb cov lus ceeb toom ntawm cov txheej txheem kho saum npoo ntawm titanium composite txheej. Vim yog lub cev thiab tshuaj lom neeg tshwj xeeb ntawm titanium txheej, titanium absorbs hydrogen ntawm 200 degree, oxygen ntawm 400 degree, thiab nitrogen ntawm 600 degree. Thaum cov txheej txheem kho deg tsis raug xaiv kom raug, cov theem nkig xws li oxides tau yooj yim tsim rau saum npoo ntawm titanium txheej thaum sib tsoo, ua rau txo qis hauv qhov huv si thiab qhov hnyav nce ntxiv, uas cuam tshuam rau kev sib txuas zoo tom qab ntawm titanium. thiab hlau. Tam sim no, kev kho tshuab, tshuaj kho mob, kev kho laser thiab lwm txoj hauv kev yog tsuas yog siv los tshem tawm cov roj av thiab oxide zaj duab xis ntawm titanium thiab titanium alloys, thiaj li yuav tau txais lub siab purity titanium txheej. Cov txheej txheem kev ua haujlwm tsuas yog siv cov cuab yeej siv tshuab, grinders, sandblasting thiab lwm txoj kev. Txawm hais tias nws tuaj yeem tshem tawm cov oxides zoo, nws siv sijhawm ntev thiab nyuaj rau kev ua cov txheej txheem titanium nrog cov chaw ua haujlwm loj thiab nyias tuab. Cov txheej txheem kev kho tshuaj muaj xws li ntxuav cov kua qaub, alkali ntxuav, tshuaj txheej, thiab lwm yam, uas tsim nyog rau kev ntxuav cov nyias nyias tab sis tawm cov txheej adsorption muaj li ntawm cov kua corroded thiab gases. Kev kho laser feem ntau yog siv los ua ib qho kev hloov kho saum npoo rau cov ntaub ntawv titanium, thiab cov qib ntawm kev ntxuav yog cuam tshuam los ntawm cov yam ntxwv xws li nws lub zog tsis muaj zog. Tam sim no, nws tsis tau muab tso rau hauv kev lag luam loj loj thiab yuav tsum muaj kev sim tshuaj xyuas ntxiv. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua qhov kev tshawb fawb tob rau ntawm cov txheej txheem kev kho deg ntawmGR2 Cladding nto ntawm Titanium Hlau Composite Phajteb rau cov ntsiab lus tseem ceeb saum toj no. Kab lus no tshawb txog qhov cuam tshuam ntawm peb cov txheej txheem, sandblasting, kua qaub ntxuav, thiab laser ntxuav, ntawm qhov chaw huv ntawm GR2 muaj cov ntshiab titanium Ua ke nrog cov txheej txheem saum npoo thiab microhardness, tsim nyog txheej txheem txheej txheem titanium txheej txheej txheej txheej txheej txheem, uas muaj qhov tseem ceeb taw qhia rau kev lag luam tsim khoom ntawm dov titanium steel composite daim hlau

 

2. Cov ntaub ntawv sim thiab cov txheej txheem

 

Kab lus no siv GR2 kev lag luam ntshiab titanium raws li cov khoom siv sim, thiab ntsuas qhov muaj pes tsawg leeg yog qhia hauv Table 1

                                               

Peb txheej txheem, uas yog sandblasting, kua qaub ntxuav, thiab laser tu, tau siv los kho qhov chaw ntawm GR2 industrial ntshiab titanium phaj. Lub macroscopic morphology ntawm GR2 nto tom qab kev kho mob yog pom nyob rau hauv daim duab 1. Thaum lub sij hawm sandblasting, 400 mesh quartz xuab zeb tau siv, thiab thaum lub sij hawm ntxuav kua qaub, ib tug tov acid tov ntawm (3mlHF+37mlHNO3+60mlH2O) tau siv; HST-100 laser ntxuav tshuab yog siv rau kev ntxuav laser, nrog lub nruab nrab wavelength ntawm 1064nm, qhov siab tshaj plaws tso zis nruab nrab lub zog ntawm 100W, thiab lub siab tshaj plaws laser mem tes zaus ntawm 200kHz. Peb qhov chaw sib txawv kho GR2 ntshiab muaj titanium daim hlau raug txiav rau hauv cov qauv nrog qhov ntev ntawm 10mm × 10mm × 10mm siv hlau txiav. Lub morphology ntawm qhov chaw thiab qhov ntev ntawm cov qauv uas tsis muaj kev kho deg tau pom siv metallographic microscope (OM) thiab scanning electron microscope (SEM), thiab qhov sib xyaw saum npoo tau txheeb xyuas los ntawm lub zog dispersive spectroscopy (EDS). Siv Qness 60 Vickers hardness tester los tshuaj xyuas qhov chaw microhardness ntawm GR2 matrix thiab cov qauv tom qab kev kho deg sib txawv.

Cov txiaj ntsig thiab kev sib tham

2.1 Kev kho Sandblasting

Qhov chaw morphology ntawm GR2 muaj cov ntshiab titanium phaj tom qab kev kho sandblasting yog pom nyob rau hauv daim duab 2 (a) thiab (b). Txhawm rau txiav txim siab lub thickness ntawm oxide txheej, morphology ntawm lub longitudinal seem perpendicular rau cov qauv nto tau pom raws li pom nyob rau hauv daim duab 2 (c), thiab EDS zog spectrum tsom xam tau ua nyob rau hauv txawv txoj hauj lwm raws li qhia nyob rau hauv Table 2. macroscopic morphology tsom xam hauv daim duab 1 (a), nws tau pom tias qhov chaw ntawm GR2 tom qab kev kho sandblasting tsis sib xws, tsis muaj qhov pom tseeb ntawm cov xim hlau thiab xim grey tsaus. Los ntawm SEM morphology kev soj ntsuam, nws tau pom tias qhov chaw ntawm GR2 tom qab sandblasting yog grooved, nrog cov khoom tsis sib xws nyob rau hauv cov matrix, nrog rau qhov me me ntawm li 30 μ lossis tsawg dua. Kev tshuaj xyuas EDS ntawm txoj haujlwm 1-4 ntawm qhov chaw qhia pom muaj cov ntsiab lus tseem ceeb O thiab Si ntawm GR2 nto tom qab kev kho sandblasting. Cov ntsiab lus O cov ntsiab lus txawv ntawm 6wt% mus rau 10wt%, thaum Si lub ntsiab lus qis dua 7wt%. Ntawm lawv, O lub ntsiab lus yog qhov seem ntawm qhov oxide nplai, thiab Si lub ntsiab lus qhia tias cov khoom tsis sib xws hauv cov matrix tau tshwm sim los ntawm cov xuab zeb quartz xuab zeb. Raws li lub zog spectrum tsom ntawm txoj haujlwm 2 (c) thiab 5, nws tuaj yeem pom tias muaj cov txheej txheem sib npaug ntawm cov oxide txheej nplua nuj nyob hauv Ti thiab Si ntawm cov qauv, nrog lub thickness ntawm li 2 μ m, thaum tsis muaj qhov pom tseeb O thiab Si ntsiab ntawm txoj hauj lwm 6, uas zoo ib yam nrog cov TA2 matrix. Qhov tshwm sim no qhia tau hais tias qhov kev huv huv ntawm GR2 tom qab kev kho sandblasting yog qhov tsis zoo, nrog cov seem oxide thiab quartz xuab zeb, uas tsis tsim nyog rau tom qab dov thiab sib xyaw ntawm titanium txheej thiab steel substrate.

2. 2 Acid ntxuav kev kho mob

Qhov saum npoo thiab ntu ntu morphology ntawm GR2 muaj cov ntshiab titanium phaj tom qab ntxuav cov kua qaub yog qhia hauv daim duab 3. EDS lub zog spectrum tsom xam tau ua ntawm ntau txoj haujlwm, raws li qhia hauv daim duab. 3

                                                 

Fig.3Nto thiab seem morphology ntawm GR2 tom qab kev kho mob pickling

Cov txiaj ntsig tau pom tias qhov kev huv huv ntawm GR2 tau txhim kho zoo tom qab kev kho cov kua qaub piv rau kev kho sandblasting, thiab cov nplai oxide saum npoo yuav luag tag nrho. Cov ntsiab lus O cov ntsiab lus tsuas yog qis dua 3wt%. Qhov sib txawv ntawm cov morphology hauv daim duab 3 (c) yog qhov sib txawv ntawm kev kho sandblasting, thiab tsis muaj qhov pom tseeb oxide txheej ntawm TA2 tom qab ntxuav cov kua qaub. Txawm li cas los xij, tom qab kev ntxuav cov kua qaub, GR2 tau hnov ​​​​mob nrog cov kua qaub sib xyaw ua ke, ua rau muaj qhov tsis sib xws ntawm cov kab xeb ntawm cov qauv, raws li pom hauv daim duab 3 (b)

Raws li kev soj ntsuam zoo ntawm lub qhov concave, nws tau pom tias muaj ntau qhov zoo thiab tsis paub txog qhov sib xyaw ua ke tau adsorbed hauv lub qhov corroded, uas yuav yog ib qho kev phom sij zais rau tom qab dov thiab sib xyaw ntawm titanium thiab hlau. Yuav kom daws tau qhov teeb meem no, tom qab pickling lub titanium txheej, nws yog ib qhov tsim nyog los ntxuav lub nto ntawm titanium cov ntaub ntawv nrog tu cov kev daws teeb meem xws li acetone los yog anhydrous ethanol. Lub morphology saum npoo ntawm GR2 ua ntej thiab tom qab ntxuav yog pom nyob rau hauv daim duab 4. Cov txiaj ntsig tau qhia tias cov kuab tshuaj organic xws li acetone tuaj yeem tshem tawm cov nplua nuj inclusions adsorbed nyob rau hauv cov kua qaub ntxuav corrosion pits, thiab txoj kev no yog cov txheej txheem tsim nyog rau titanium steel composite daim hlau. nrog titanium txheej.

 

3. Csuav nrog

 

(1) Tom qab kev kho sandblasting, nto ntawm GR2 yog grooved nrog residual oxides thiab quartz xuab zeb. Cov ntsiab lus ntawm O lub ntsiab lus yog nruab nrab ntawm 6wt% thiab 10wt%, thiab lub thickness ntawm oxide txheej yog li 2 μ m. Qhov saum npoo microhardness yog hais txog 290HV.

(2) Tom qab ntxuav cov kua qaub, cov nplai oxide ntawm qhov chaw ntawm GR2 raug tshem tawm tag nrho, thiab cov khoom siv zoo yog adsorbed hauv cov qhov dej hauv zos. Acetone yuav tsum tau siv los ntxuav ntxiv. Qhov saum npoo microhardness yog ze rau GR2 substrate, uas yog hais txog 220HV, ua rau nws tsim nyog titanium txheej txheej txheej txheej txheej txheem.
