, Cov khoom siv cov khoom siv: corrosion pheej hmoo ntawm cov roj carbon hlau siab thiab cov txiaj ntsig buffering ntawm laminated qauv
1. Ntuj corrosion nyiam ntawm cov pa roj carbon hlau siab
Tsoos ib txwm muaj lub txim muaj lub txim feem ntau yog muaj cov roj carbon hlau (xws li txheej txheem roj hmab (xws li txheej txheem roj carbon monoxide}}%, tab sis cov ntsiab lus chromium feem ntau tsawg dua 0.5%. This component leads to electrochemical corrosion of cutting tools in humid environments: micro cells form on the surface of carbon steel, and iron ions react with water and oxygen to form reddish brown rust (Fe ₂ O ∝· nH ₂ O). Kuaj cov ntaub ntawv sim ua pom tias muaj xeb roj carbon monomascus nyob rau hauv 4 teev nyob rau hauv ib puag ncig nrog 304 teev rau 304 stainless hlau los txhim kho cov hlau corrosion.
2. Corrosion Buffing Mechism ntawm Laminated qauv
Cov txheej txheem Forging ntawm Damascus riam (xws li folding hlau nrog ntau tshaj 300 txheej txheej) ua rau cov microstructure nrog kev hloov cov khoom mos thiab nyuaj. Cov txheej txheem ntawm cov tawv muag (xws li 15N20, muaj 0.8% -1.2% npib dense, uas tuaj yeem ncua kev nkag mus rau hauv lub hard steel core (xws li 1095). Raws li kev soj ntsuam tiag tiag los ntawm cov neeg yos hav zoov hauv zej zog, tom qab tau siv cov ntses sib txawv, tab sis cov tawv tawv ntawm cov pob zeb sib sib zog, tab sis cov tawv tawv steel uas poob qis ntawm 0.1-0.3mm.
3. Qhov kev txwv ntawm cov hlau tsis xeb hlau Damascus
Qee cov Damascus niaj hnub siv cov hlau tsis muaj roj (xws li 440C lossis VG-10) raws li cov ntsiab lus chromium ntawm 11%-the -13%, the sorompital muaj peev xwm tiv thaiv tau xeb puas tau haus. Txawm li cas los xij, nws interlayer tsev muaj zog yog txwv los ntawm cov hlau stainless hlau, thiab nws yog ib tus mob interlayer delamination thiab condaction rau hauv cov chaw puag ncig cua noo. Tom qab siv qee hom ntawm stainless hlau Daboscus riam los ntawm kev sib koom ua ke hauv nroog, thiab cov khoom siv hauv nroog tsis muaj peev xwm ua tsis tau kev pheej hmoo ntawm cov av noo.
2, Ib puag ncig kev txhim kho corrosion: Composite Yaig Cov Lus Qhia hauv Riverside scenes
1. Cov nyhuv synergistic ntawm cov av noo thiab salinity
Ib puag ncig riverside feem ntau nrog cov av noo (80% -95%) thiab nto salinity (xws li cov ntsev ntau ntawm 3% -5% hauv cov chaw dej hiav txwv). Ntsev yog adsorbed mus rau saum npoo ntawm cov cuab yeej txiav los ntawm kev txiav txim siab capillary, ua cov tshuaj electrolyte uas nrawm electrochemical corrosion. Cov ntaub ntawv ntsuas tiag tiag qhia tau hais tias hauv cov ntsev uas muaj lub Damascus yog 3.7 ntau dua li cov kab mob ntshiab (thiab cov pits sib sib zog nrog txoj kab uas hla ntawm 0.5-2mm).
2. Catalytic cov nyhuv ntawm cov organic residue
Riverside ua haujlwm feem ntau koom nrog txiav ntses, thiab lwm yam hauv lawv lub cev muaj kev xeb nrog tshuaj corrosive worsures nrog chloride ions (cl ⁻). Cov neeg nuv ntses hauv zej zog tau tshaj tawm tias tom qab siv Damascus riam los kho cov ntses salmon, yog tias tsis muaj xeb rau hauv cov xeb ntev dua 28 teev. Qhov kev ua kom nrawm no yog tshwm sim los ntawm cov kev yaig synapistic ntawm acidic (ph 4-5) tsim los ntawm protein decomposition thiab chloride ions.
3. Kev ntxhov siab corrosion los ntawm kev hloov pauv hloov
Qhov kub sib txawv ntawm ib hnub thiab hmo ntuj los ntawm tus dej tuaj yeem ncav cuag 10-15 degree, ua rau thermal expansion thiab meraction ntawm cov khoom siv. Qhov sib txawv hauv kev nthuav dav coefficient ntawm cov tawv mos thiab tawv hlau ntawm cov hlau Lamination Dabascus thiab txog 12 ⁻⁶ /℃rau interration kev ntxhov siab thiab ua kom nrawm dua qhov kev nkag siab ntawm corrosive media. Tom qab siv qee hom cuab yeej ntawm cov chaw los ntawm tus dej tau 3 lub hlis, ib qho 0.2mm interlayer tawg, xyuas qhov kev txhawb nqa ntawm kub hloov pauv ntawm kev xeb.
3, kev tiv thaiv kev tiv thaiv kev siv tau xeb: los ntawm kev tiv thaiv kev tiv thaiv
1. Kev tu kom huv thiab ziab
Tam sim ntawd yaug cov hniav nrog dej deionized tom qab siv kom tsis txhob khawb qhov chaw vim tias ntsev crystallization; Tom qab ntawd siv lub microfiber (xws li cov tawv nqaij microfiber) kom nqus cov xim mos lwj) kom nqus noo noo, thiab tsis so kom tiv thaiv kev puas tsuaj rau cov qauv acid. Kev sim hauv zej zog qhia tau hais tias kev ntxuav sijhawm kom txo tau cov mob corrosion ntawm Damascus los ntawm 68% nyob rau hauv cov puag ncig huab cua. Rau cov kov, cov ntaub ntawv ntuj (xws li Walnut) yuav tsum tau qhwv rau hauv cov ntaub yas qhuav, thaum cov khoom siv hluavtaws (xws li G10) tuaj yeem so ncaj qha.
2. Daim ntawv thov ntawm kev tiv thaiv kev tiv thaiv
Cov roj av roj txheej: Khoom noj khoom haus cov roj me (xws li cov roj ntxhia nplua nuj) tuaj yeem tsim cov hniav Hydrophobic) tuaj yeem thaiv kev sib cuag ntawm dej thiab oxygen. Kuaj kab Damascus tau coated nrog roj tsis tau pom xeb tom qab 72 teev nyob rau hauv 90% av noo ib puag ncig.
Siv cov ntaub ntawv pov tseg ciab: kev sib xyaw ntawm beeswax thiab brazilian xibtes ciab (melting taw tes 60}} Cov neeg nuv ntses qhov ntsuas pom tau hais tias tom qab siv WAX sib tsoo riam los ntawm tus dej rau ib lub hlis, qhov xeb xeb txo qis los ntawm lub cev tsis tuaj yeem kho cev.
Tej hub txheej: qee qhov siab -}}}}} }ness layer້ນ }0 layer-1 5 μ0000, uas tuaj yeem muab ob qho kev siv xeb thiab hnav tsis kam. Txawm li cas los xij, nws tus nqi yog 300% siab dua kev ua yeeb yam thiab tam sim no tsuas yog siv rau cov cuab yeej txiav tsawg.
3. Kev ua kom zoo ntawm kev cia ib puag ncig
Daim ntawv thov kev txiav txim dehumidifier: tso cov pob zeb Silicone Desiccant (noo noo) ntawm rab riam riam tuaj yeem tswj hwm lub vaum noo qis dua 40%. Lub zej zog cov tswv yim tswv yim pom tau hais tias tom qab siv DeHumidifiers, Qhov kev loj hlob ntawm corrosion kev loj hlob ntawm kev txiav cov cuab yeej tau poob qis ntawm 5.2% mus rau 0.8%.
Kev rho tawm Chaw Cia: Zam kev sib cuag ncaj qha nrog cov khoom hlau (xws li cov yuam sij thiab cuab yeej) los tiv thaiv cov corrosion corrosion. Nws raug nquahu kom siv cov ntaub ntawv muaj mob siab (xws li Kydex cov ntaub ntawv) lossis ib rab riam ywj siab, ua kom lub taub hau ntawm rab phom kom yooj yim.
Lub teeb tswj: ntuj kov cov ntaub ntawv (xws li kausmoth kaus ntxhw) yuav tsum tau muab cia kom tiv thaiv kom tsis txhob muaj kev tiv thaiv ultraviolet tshwm sim los ntawm ultraviolet rays. Lub tsev khaws puav pheej sau tau qhia tias kev kov ntawm lub hnub Damascus, uas tau raug rau lub hnub ci rau lub hnub ntev, tau tsim kho 0.5mm 0.5mm tawg tsis pub dhau 5 xyoos.
4, kev lag luam kev lag luam: xeb tiv thaiv kev daws teeb meem rau cov neeg siv kev tshaj lij
1. Cov neeg nuv ntses "peb -}}}}}}}}}
Alaska cov neeg nuv ntses siv tau ib qho "yaug dej so dej" tam sim ntawd yaug cov dej tshiab, thiab thaum kawg siv ib txheej ntxhia ntawm cov roj ntxhia. Cov phiaj xwm no txuas lub neej lub neej txij li 2 xyoos mus rau 5 xyoos thiab txo cov nqi txij nkawm los ntawm 40%.
2. Kev tiv thaiv cov lus qhia rau cov lus qhia sab nraum zoov
Cov qauv kev coj ua kev sib cais tiv thaiv kev kho mob txhua hnub thiab kev sib sib zog nqus txij nkawm: tsuas yog ntxuav thiab qhuav tom qab siv txhua hnub; Ua hauv - Kev Txij Nkawm} Kev Txij Nkawm Ib Leeg, suav nrog WAX cov khoom qub, thiab tshuaj xyuas cov ntaub ntawv tshiab, thiab kuaj cov kev nruj ntawm tus kov. Raws li cov ntaub ntawv taug qab los ntawm ib pab neeg qhia pab pawg, txoj kev daws teeb meem no tau raug txo cov cuab yeej ua tsis tiav ntawm 18% mus rau 3%.
3. Chaw Tsim Tshuaj Cov Khoom Siv Tsis Tau
Qee hom lag luam tau tsim "huab cua tiv taus Damascus", uas txhim kho nws txoj kev tiv thaiv los ntawm kev ntxiv 0.3% -0.5% molybdenum (mo) thiab vanadium (v). Cov ntawv xeem tau qhia tias cov xeb ntawm cov hlau hauv cov ntsev uas muaj cov khoom siv Damascus Steel, tab sis tus nqi nce li 25%.
