, Lub ntsiab lus ntawm cov qauv: 'microstructure ntawm ntau - fawm kib
Tus qauv ntawm lub Damascus riam los ntawm Forging Txheej Txheem ntawm Ntau {{} Filling txheej hlau. Tsoos ib txwm muaj lub nroog Damascus Steel yog tsim los ntawm kev sib txawv stacking powering carbon hlau thiab forging lawv los ua ntau txheej ntawm cov khaubncaws sab nraud povtseg ntawm cov hlau. Hauv lub tshuab tsom iav, cov qauv txheej txheem tshwm sim raws li kev faib tawm ntawm carbide, thaum macroscooth lawv tshwm sim raws li distorted vortices, trapezoids, lossis dej nag zoo li cov qauv nag. Niaj hnub no Stainless Damascus cov hmoov hlau metallurgy, thiab nias hmoov thiab nias cov hmoov sib txawv ntawm kev kho cua sov.
Cov ntsiab lus tseem ceeb: Txawv yog macroscopic manifesting ntawm qhov sib txawv ntawm cov qauv tshuaj lom neeg nyob nruab nrab ntawm cov hlau nyuaj siab ntawm cov khoom siv.
2, Tub ntxhais ntawm anti - corrosion kev ua tau: alloy muaj pes tsawg leeg thiab kev kho kom nto
1. Lub luag haujlwm tseem ceeb ntawm alloy muaj pes tsawg
Lub corrosion tsis kam ntawm Damascus riam yog tsuas yog txiav txim siab los ntawm lawv cov alloy muaj pes tsawg leeg:
Chromium (CR): Cov tub ntxhais lub ntsiab ntawm cov hlau tsis xeb, nrog cov ntsiab lus ntawm tsawg kawg 10,5% los tsim ib qho kev ua yeeb yam cheem chomium oxide tiv thaiv zaj duab xis. Piv txwv li, Damastel tus Damascus Steel siv 304L thiab 316%, thiab nws cov pa roj carbon ntau dua li cov pa roj carbon monasclus.
Nickel (NI): Synergizes nrog chromium los txhim kho kev ruaj ntseg ntawm cov zaj duab xis passive, feem ntau pom hauv 316L alloy.
Molybdenum (mo): Txhim kho kom tsis txhob pitting corrosion, tshwj xeeb tshaj yog nyob rau hauv chlorine muaj ib puag ncig ib puag ncig.
Piv txwv li cov ntaub ntawv: Cov khoom siv Wootz steel muaj cov ntsiab lus carbon ntau tab sis cov ntsiab lus chromium tsawg, thiab xav tau kev tswj xyuas nquag thiab saib xyuas kom tsis txhob muaj xeb; Niaj hnub no stainless hlau Dabascus Steel tseem tuaj yeem tswj nws cov lus tshaj tawm hauv ib puag ncig noo.
2. Kev cuam tshuam txog kev kho mob saum npoo
Cov tsos ntawm tus qauv nyob ntawm seb cov txheej txheem kho mob, thiab cov qauv kev kho mob ncaj qha cuam tshuam rau kev tiv thaiv corrosion:
Acid etching: corroding sib txawv hlau txheej nrog cov acid muaj zog los ua qauv qauv. Yog tias seem realidual tsis yog ua kom tiav tom qab ntxuav cov kua qaub, nws tuaj yeem ua rau corrosion hauv zos.
Nano txheej: Qhov tseeb thev naus laus zis, xws li Huxia Jase Nasating, tuaj yeem tsim zaj duab xis thiab pob tshab tiv thaiv cov yeeb yaj kiab ntawm cov hniav. Cov kev sim tau qhia tau tias nws cov nyhuv xeb yog ob peb zaug siab dua li qhov chaw tsis muaj txiaj ntsig, thaum txhim kho qhov pom ntawm cov qauv.
Neeg kho tshuab polishing: du surfaces tuaj yeem txo cov nplaum ntawm cov xov xwm corrosive, tab sis muaj ntau polishing tej zaum yuav ua rau cov zaj duab xis passive.
Cov ntaub ntawv kev lag luam: Damascus Steel riam kho nrog nano txheej muaj lub sijhawm ntev los ntawm 12 teev mus rau ntau tshaj 72 teev hauv cov ntsev ua tshuaj tsuag.
3, kev sib tham sib txawv ntawm cov qauv thiab corrosion tsis kam
1. Scenarios Qhov chaw uas cov qauv yuav txo corrosion tsis kam
Tsoos muaj pa roj carbon hlau Damascus: Yog tias cov roj chromium tsawg (xws li cov ntsiab lus chromium muaj li ntawm 13%) yog siv, cov khoob khoob ntawm kev corrosion. Tshwj xeeb tshaj yog rau tes forged txiav cov cuab yeej, folding tsis txaus txheej txheej lossis kev tswj hwm qhov kub thiab txias ua rau mob carbAnic corrosion thiab micro galosion.
Neeg kho tshuab plug vuam qauv txiav cov cuab yeej: ib co khoom lag luam muaj cov khoom lag luam tsis muaj zog vim muaj kev ntxhov siab, ua rau kev xeb.
2. Scenarios Qhov chaw uas cov qauv yuav txhim khu kev txhim kho corrosion
Stainless hlau hmoov Damascus: xws li cov txiv kab ntxwv swedish (swedish txheej thiab cov qauv txheej txheem yog sib xws yog sib txawv, nrog tsis muaj qhov sib txawv hauv kev xeb tawm tsam. Cov poj niam mosaic los yog cov qauv ntaiv tsuas yog kev tsim qauv pom thiab tsis cuam tshuam rau qhov tseem ceeb ntawm cov khoom siv.
Composite qauv txiav cov cuab yeej: qee qhov siab -}}} end end្ endាត់ yeej (xws li sawv daws ua kom nruj thiab txhim kho tag nrho cov corrosion.
4, Kev Lag Luam Kev Lag Luam thiab Cov Neeg Siv Cov Lus Qhia
1. Chaw tsim khoom teb cov lus teb
Xaiv cov khoom siv: High corrosion resistant alloys xws li 316l lossis nitro-}}}}}}}}}}}}}}}}}}}}} lub sij hawm ruaj khov.
Cov txheej txheem optimization: tswj cov forging qhov kub ntawm 950-1050℃kom zam dhau cov nplej zom; Tom qab siv cov kua qaub, cov tshuaj alkaline tau siv rau kev nruab nrab kom txo qis kev pheej hmoo ntawm hydrogen clrittlement.
Txheej Txheej Innovation: Tsim Pob Zeb Diamond- Zoo li cov pa roj carbon (DLC) Txheej Txheem Kev Tiv Thaiv thiab Kev Txiav Txim Kev Sib Tw.
2. Tus neeg siv kev siv thiab txij nkawm
Kev tswj hwm ib puag ncig: zam kev txwv ntev -}}}}}}}}} tsuag, lossis cov chav ua noj, ntug dej hiav txwv).
Kev Tu Tu: Tam sim ntawd so qhuav tom qab siv, tsis tu ncua cov roj ntxhia lossis tshwj xeeb xeb inibitor.
Kho cov kev ntsuas: Yog tias xeb me ntsis tshwm sim, lawv tuaj yeem yog qhov av maj mam nrog 1000 grit sandpaper thiab tom qab ntawd coated nrog hlau tiv thaiv muab tshuaj txhuam.
