一, cov qauv kev coj ntawm Damascus riam tiv thaiv txheej
Cov txheej tiv thaiv ntawm lub Ramascus riam muaj peb ntu:
Acid etched qauv txheej: los ntawm kev siv cov kua qaub ua kua (xws li cov hlau corricide) rau corrode lamination steel, kev ntxhib los mos nrog kev sib txawv ntawm lub teeb thiab tsaus nti yog tsim. Cov txheej no muaj tuab ntawm tsuas yog 0.01-0.05mm thiab yog qhov tseem ceeb ntawm kev pom kev zoo nkauj.
Oxidation passivation txheej: ib qho txheej txheem ib txwm muaj fe α o ₄ idekide zaj duab xis tom qab high}} kub quenching thiab noo noo.
Txheej Txheej Tiv Thaiv: Ib qho kev siv roj ntxhia, beeswax lossis nano cerams ntawm 0.005- 0.02mm, muab cov kev tiv thaiv xeb ntev.
Peb txheej txheej txheem ntawm cov qauv ua ke ua cov txheej txheem tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv, thiab kev puas tsuaj rau ib txheej yuav ua rau cov saw sib txig. Piv txwv li, puas tsuaj rau cov kua qaub etching txheej yuav ua kom nrawm nrawm ntawm oxide txheej, yog li txo cov nplaum ntawm txheej.
2, cov txheej txheem txheej txheem thiab muaj feem cuam tshuam ntawm cov xuab zeb polishing
Sandpaper Kev Tshem Tawm Tawm Sab Micro Protrusions los ntawm kev sib txhuam tshuab los ntawm peb qhov tsis sib xws:
Xaiv Mesh xaiv: 800 mesh lossis tsawg yog suav tias yog kev sib tsoo coarse thiab yog siv los kho cov khawb khawb; 1000-3000 mesh yog kev sib tsoo zoo, uas tuaj yeem tshem tawm cov tsis meej; Daim iav polishing nrog ib grit ntawm ntau tshaj 5000 tuaj yeem txhim kho glossiness.
Kev tswj siab: nws raug pom zoo kom siv lub hauv paus ntsiab lus ntawm "lub teeb siab ntau zaus", raws li siab tshaj 5n / cm ² yuav ua rau cov kua acid corrosion los tev tawm.
Yuav kom tsis txhob txhuam cov hniav sib dhos kom tsis txhob sib deev.
Raug ntaub ntawv xaiv:
Kho cov khawb tsim tsim kom muaj kev thauj mus los (thawj zaug lees paub tias cov khawb tsis tau nkag mus rau Oxide Txheej)
Tshem tawm oxidation spotes tsim los ntawm ntev - sij hawm cia (yuav tsum tau ua ntej- kev kho nrog acidic ntxuav cov neeg sawv cev)
Txhim khu cov hniav glossined ntawm cov hniav (kom ua tom qab txheej hloov tshiab)
3, muaj peev xwm muaj peev xwm thiab cov kev mob tshwm sim ntawm cov xuab zeb polishing
1. Lub cev tsis muaj zog rau cov kua qaub etching txheej
Ib qho cuab tam Rhiav kev sim ua kom pom tias tom qab polishing nrog 2000 grit sandpaper, cov tuab ntawm cov acid poob qis los ntawm 42%, ua rau 67% txo qis hauv kev sib txawv. Ntau dua tiag tiag, cov hlau faib tsim los ntawm kev hnav tuaj yeem tso rau hauv oxide txheej, ua "pseudo xeb" uas yuav tsum tau rov ua dua los ntawm kev ntxuav cov kua qaub.
2. Kev rhuav tshem ntawm Oxide Txheej Txheej Txheej Txheem
Mechanical txhuam yuav tawg cov qauv tuab ntawm fe α o ₄ thiab tsim microcracks. Cov ntaub ntawv German kuaj pom tias xeb tus hniav kho nrog cov xuab zeb tau nce los ntawm 3.2 zaug hauv cov tshuaj ntsev tshuaj ntsuam. Hom kev puas tsuaj no yog zais thiab feem ntau tsuas yog ua pom meej tom qab 3-6 lub hlis ntawm cia.
3. Txo cov nplaum ntawm txheej
Qhov saum npoo roughness (RA tus nqi) tom qab cov paj ntaub polishing yuav txo qis qis dua 0.1 μ m, ua rau cov txheej txheej rau hauv cov hlau ua kom pom tseeb. Cov kev sim tau qhia tias cov roj ntxhia tau thov rau cov chaw zoo li muaj lub neej luv ntawm 6 lub hlis mus rau 3 lub lis piam.
4. Kev pheej hmoo ntawm tshav kub thaj chaw
Kev kub ceev kev sib txhuam yuav ua rau muaj qhov kub hauv zos kom nce siab dua 200 degree, ua rau ob qhov teeb meem:
Oxidation Txheej Theem Kev Hloov: Fied o α yog hloov mus rau hauv FE ₂ o ₂ o α, thiab cov xim hloov ntawm dub rau xim av liab
Txheej PowerBiancy: Organic Txheej Txheem Pib Decompose rau saum toj no 150 Qib, Tsim Cov Glufuls
4, kev tshuaj ntsuam cov kev daws teeb meem thiab lwm cov thev naus laus zis thev naus laus zis
1. Staged polishing txuj
Ua ntej ua tiav theem: Siv 600 grit sandpaper kom tshem tawm cov tsis xws luag (siab tsawg dua lossis sib npaug nrog 3n / cm ²)
Kev Ua Ntawv Txhim Kho Theem: Siv 1000 grit Sandpaper ua ke nrog polishing muab tshuaj txhuam (suav nrog alumina micro hmoov)
Kev Tiv Thaiv theem: Thov cov nano ceramic txheej tam sim ntawd tom qab polishing (tuab tswj ntawm 0.01 hli)
2. Cov tswv yim pom zoo
Ultrasonic Tu: Siv 40kHz Siab Siab - zaus Kev co kom tshem tawm cov av hauv av, tsis muaj kev pheej hmoo ntawm kev puas tsuaj ntawm kev puas tsuaj
Laser Polishing: los ntawm kev siv cov pulsed laser kom yaj nto micro protrusions, qhov raug mus txog 0.001 hli
Tshuaj lom neeg polishing: Siv phosphoric acid nitric acid nitric acid nitric sib tov (piv 3: 1) rau kev tswj hwm corrosion, tab sis yuav tsum muaj kev tshaj lij
3. Tshwj xeeb Scarario tuav
Rust pin kho: soak nyob rau hauv 3% citric acid daws rau 10 feeb ua ntej, thiab tom qab ntawd thov 3000 grit Sandpaper rau kev kho mob hauv cheeb tsam
Txawv Txhim Kho: Tom qab polishing, ua kom huv si acid ntxuav (concentration ntawm ferric chloride daws 5%, sijhawm tsawg dua lossis sib npaug li 3 feeb)
Lub Sij Hawm Ntev: Tom qab polishing, thov nqus cov ciab, uas tuaj yeem cais cov cua rau ntau tshaj 5 xyoos
5, kev tswj hwm kev nyab xeeb kev nyab xeeb
Kev tiv thaiv tus kheej: N9MSHIPS, txiav hnab looj tes tiv thaiv, thiab goggles yuav tsum tau hnav
Kev tswj ib puag ncig: cov av noo nyob rau thaj chaw ua haujlwm yuav tsum khaws cia ntawm 40-60% rh, thiab qhov kub yuav tsum tsawg dua lossis sib npaug ntawm 25 degree
Kev Tswj Tool: Sander yuav tsum muab cia los ntawm mesh kom tsis txhob muaj kev sib kis
Khib nyiab: xuab zeb uas muaj cov hlau hmoov av tau cais tias yog cov khoom pov tseg thiab xav tau pov tseg raws li kev tiv thaiv ib puag ncig nrog kev tiv thaiv ib puag ncig
6, kev soj ntsuam raug
Rooj plaub 1: polishing heev ua rau ploj ntawm cov qauv
Ib tug sau siv 800 grit sandpaper rau Polish ib tug antique rab riam, ua rau cov kua qaub etching etching ib txheej rau tev tawm. Kho kom kho cov qauv pickling, tab sis cov txheej txheem ntawm thawj tus qauv tsis tuaj yeem ua dua tshiab, ua rau 70% txo hauv cov cuab yeej tus nqi.
Rooj plaub 2: corrosion tshwm sim los ntawm kev ua haujlwm tsis raug
Ib qho kev nyiam sab nraud yuav tsum siv cov ntaub ntawv sab nraud mus rau cov cuab yeej Polish txiav, tab sis ua tsis tiav los thov cov roj tiv thaiv nyob rau hauv lub sijhawm. Peb lub lis piam tom qab, chaw xeb tau pom ntawm cov hniav, uas tau kuaj pom raws li electrochemical corrosion los ntawm microcacks hauv cov oxide txheej.
Rooj plaub 3: Kev Tshawb Fawb Kev Tshawb Fawb Txhim Kho Kev Ua Tau Zoo
Ib qho kev sib koom ua ke siv cov txheej txheem sib txhuam ntawm cov txheej txheem los ua cov txheej txheem ntawm cov cuab yeej txiav customized. Tom qab tshuaj tsuag tshuaj ntsuam xyuas cov ntaub ntawv pov thawj, nws txoj kev tiv thaiv nws xeb Mus txog The ISO 9227 tus qauv NSS 1000 teev qib, uas yog peb zaug siab dua li kev ua yeeb yam.
