Dab tsi yog kev txij nkawm txoj kev rau Damascus riam?

, Cov khoom siv cov khoom siv txiav txim siab saib xyuas cov tub ntxhais txij nkawm: Qhov kev sib tw ntawm xeb xeb thiab kos kev tiv thaiv
Lub ntsiab ntawm Damascus Steel yog cov siab carbon hlau (nrog rau cov ntsiab lus carbon (nrog cov yam ntxwv carbon monoxide yog qhov tseeb micro serrated cov lus faib ntawm carbides. Txawm hais tias tus qauv no xaus rau cov twj txiav nrog kev txiav kev zoo heev, nws kuj coj ob txoj kev taug kev loj:
Oxidation tau: Cov ntsiab lus Chromium cov ntsiab lus ntawm cov hlau muaj tsawg dua 5%, nyob rau hauv cov hlau tsis muaj zog, uas ua rau nws muaj cov dej noo thiab cov pa taws rau saum huab cua. Kev sim cov ntaub ntawv qhia tau tias nyob ib puag ncig nrog cov av noo, tsis kho cov khaub ncaws carbon hlau Damascus pob ntseg tsis pub dhau 24 teev thiab daim ntawv xim av liab qab xim ua ntej 72 teev.
Cov qauv hniav zoo li: Cov qauv hniav yog qhia los ntawm acid etching txheej txheem, thiab nws cov microstructure los ntawm honeycomb zoo li lub hws honeycomb. So cov ntaub ntxhib yuav ua rau cov npoo ntawm cov hws thiab ua rau cov qauv plooj. Ib qho kev sib piv hauv qee qhov chaw kuaj xyuas uas tau ua kom so nrog cov ntaub plaub hlau, qhov kev sib cuam tshuam ntawm cov hniav txo qis los ntawm 37%, thiab qhov sib piv ntawm tus qauv txo qis los ntawm 62%.
Kev daws:
Kev xaiv tu cov cuab yeej: Tsis yog velvet paj rwb ntaub, ultra- Txoj phuam zoo, lossis cov Suede Tshwj Xeeb yuav tsum tau siv. Rau stubborn stains, soak nyob rau hauv boiled flaxseed roj rau 10 feeb ua ntej, thiab tom qab ntawd maj mam so nrog daim ntaub paj rwb.
Rust tshem tawm thev naus laus zis: rau cov oxidation me me, 3000 grit sandpaper tuaj yeem siv rau polish raws txoj kev ntxhib los mos ntawm ib qho kev taw qhia; Yuav tsum xeb yuav tsum tau siv xeb kev xeb (muaj citric acid), sib xyaw nrog cov plaub fab paj nruag rau polishing ntawm 500 lub sij hawm ib feeb; Kev sib zog xeb hnyav yuav tsum tau xa rov qab mus rau thawj lub Hoobkas rau electrolytic tshem tawm.
2, ib puag ncig tswj: tsim ib qho "peb tiv thaiv" cia
Qhov chaw cia ib puag ncig ntawm Damascus yuav tsum tau raws li peb qhov tseem ceeb tiv thaiv, kev tiv thaiv plua plav, thiab kev tiv thaiv qhov kub thiab qhov kub thiab kub
Kev tswj kom sov noo: Qhov kev cia siab tagnrho cov av noo yog 45% -55%. Thaum cov av noo ntau dua li 70%, cov khoom lag luam hauv hluav taws xob (pom zoo hom: Lub txee qhuav) yuav tsum tau siv. Saib xyuas cov ntaub ntawv los ntawm qee lub tsev khaws puav pheej riam qhia tau tias tus corrosion tus kheej khaws cia cov av noo khaws cia los ntawm 89% piv rau ib puag ncig ib puag ncig.
Kev tswj qhov kub thiab txias: Zam txhob kis rau hauv qab no 0℃lossis siab dua 40 degree. Tsis tshua muaj kub tau ua rau cov hniav tawg ua kom tawg, thaum lub sij hawm siab nrawm nrawm nrawm nrawm ntawm cov roj. Cov kev sim tau qhia tau tias khaws cia ntawm 60℃rau 24 teev kom txo cov tuab ntawm riam riam tiv thaiv los ntawm 63%.
Kev Tiv Thaiv hmoov av: Lub hardness ntawm silica hais hauv plua plav mus txog MoHS 7, thiab kev sib txhuam nrog cov hniav yuav ua rau khawb. Nws raug nquahu kom siv cov riam hluav taws ntoo ntawm lub thawv nrog cov hlua khi thiab hlua nrog cov pa roj carbon adsorbent. Kev sim ntawm ib tug customized riam rhiav qhia tau tias qhov kev cia no yuav txo qhov teeb meem ntawm khawb ntawm cov hniav los ntawm 92%.
Cov xwm txheej tshwj xeeb tuav:
Kev Siv Sab Nraud: Nruab nrog riam phom nrog noo noo tsis kam ntawm sheath nrog kub plaub hau ntawm 50 degree) tom qab rov qab mus rau qhov chaw nres tsheb.
Kev Siv Chav Ua Noj Ua Noj: Tom qab txiav cov khoom xyaw acidic (xws li txiv qaub thiab txiv lws suav), pH {{{{}}), thiab tom qab ntawd yaug nrog dej distilled.
3, Kev khiav hauj lwm cov qauv: tsim cov txheej txheem txij nkawm
1. Kev ua tiav tom qab siv
Kev ua haujlwm txiav: Tom qab ua tiav cov kev txiav, yaug cov hniav nrog dej ntws, tsom mus tu ntawm ntug thiab tes ua si sib koom tes. Rau cov tshuaj pleev cov tshuaj (xws li cov tsiaj rog tsiaj), ib qho khoom noj paj rwb kev kho mob sopped hauv 95% cawv tuaj yeem siv rau so.
Tom qab ua si nrog nws: sodium chloride nyob rau hauv tib neeg hws tuaj yeem ua kom nrawm corrosion. Tom qab ua si nrog nws, nws yog ib qho tsim nyog yuav tsum ua rau nws nrog ethanol thiab thov ib txheej riam diav nyias nyias.
2. Kev Tu Siab Me Nyuam
Kev Txij Nkawm: Poob ib qho nyiaj me me ntawm cov ntaub dawb nyob rau hauv cov ntaub ntawv paj rwb thiab muab tso rau hauv cov yeeb yaj kiab sib xws nrog cov xim huv ntawm 0.01mm. Rau Rosewing rab riam, ntuj beeswax (melting taw tes 62-65 degree) yuav tsum tau thov kom tiv thaiv kev tawg.
Kev Txij Nkawm Txhua Hli Cov kauj ruam yog raws li hauv qab no:
Disassemble qhov kov (yog tias nws yog ib qho qauv tshem tawm)
Huv si nrog ultrasonic tu tshuab (zaus 40kHz) rau 5 feeb
Qhuav ntawm 120℃rau 30 feeb
Thov NANO CAUBFASS (tuab 0.002 hli)
Tom qab sib dhos, cia nws sawv ntsug rau 48 teev
3. Lub Sij Hawm Ntev Cov Qauv
Pre sealing treatment: Apply anti rust wax (containing microcrystalline wax) to the blade, and wrap the handle with acid-base balance paper. Cov khoom lag luam tub rog tau pom tias txoj kev kho mob no tuaj yeem ua kom lub cuab yeej txiav xeb dawb rau 500 teev hauv cov ntsev tshuaj tshuaj.
Kev sib khi ib puag ncig: lub thawv kaw uas muaj nitrogen, nrog oxygen conctrolation tswj hauv qab 0.5%. Qhov chaw ib puag ncig no tuaj yeem ua tiav kev txwv oxidation, ua rau muaj qhov sib txawv ntawm tsawg dua 5% ntawm cov cuab yeej cia lub xeev thiab lub Hoobkas lub xeev.
4, kev pheej hmoo kev pheej hmoo: tsib txoj haujlwm taboos
Txwv kev txwv tom qab sib ntswg: Tom qab cov hniav tau kos rau hauv cov khoom, kev nyuaj siab shear tau tsim los ntawm kev sib tw tom qab, uas tuaj yeem ua rau muaj kev puas tsuaj rau kev puas tsuaj.
Zam kev hloov tam sim no tam sim no: Hloov pauv hloov pauv ntawm cov hniav kub tshaj 80℃tuaj yeem ua rau cov txheej quenching rau tev tawm. Cov riam riam tau tawm ntawm lub tub yees yuav tsum tau sab laug ntawm chav tsev kub rau 2 teev ua ntej ntxuav.
Tshem tawm kev sib cuag tshuaj: Tsis txhob siv cov tshuaj kho muaj cov kuab tshuaj xws li WD-40, raws li lawv tuaj yeem puas cov pickling txheej ntawm hniav. Pom zoo kom siv cov roj me me (xws li roj me).
Tiv thaiv kev sib tsoo nrog cov khoom siv nyuaj: yog tias cov hniav sib tsoo nrog cov khoom xws li hlau lossis pob zeb nrog HRC55 ntau tshaj li tsis pom lub qhov muag liab qab. Thaum khaws cia, cov cuab yeej siv ywj siab yuav tsum tau siv kom tsis txhob siv cov cuab yeej sib cuag.
Use electric tools with caution: If the speed of the electric sharpener is too high (usually>3000 lub sijhawm ib feeb), nws yuav tsim kom muaj kev kub ntxhov thiab ua kom cov qauv cua sov ntawm cov hniav. Nws raug nquahu kom siv cov pob zeb nrawm thiab tswj lub kaum sab xis ruaj khov ntawm 15-20℃rau kev tuav sib tsoo.
5, Kev Tu Siab Tshaj: Microstructure kho tshuab
Rau siab -}}}}} ເ damັດ Damascus riam, ib txwm Microstructure Kev yuav tsum tau:
Metallographic Kev Ntsuam Xyuas: Txhua 2 xyoos, siv lub tsom iav kho qhov muag (ua kom rov qab los kuaj xyuas cov qauv Hniav, thiab xa rov qab sai sai rau kev kho yog tias mob carbide cais.
Laser nto kev kho mob: mem tes laser (wavelength 1064nm) yog siv los ua micro microses thiab txhim kho corrosion tsis kam. Kev kuaj sim ua kom pom tias qhov kev kho no tuaj yeem txuas ntxiv cov ntsev pov tseg kev kuaj xyuas lub sijhawm txog 1000 teev.
Ion Tsis txhob siv tshuab hluav taws xob tau txhaj rau hauv cov hniav uas tawv tawv ntawm 0.2 μ m, nce qhov tawv ntawm 0.2 μ-70-70 thaum tswj hwm kev nruj ntawm cov tub ntxhais.
