Ib, Yuav ua li cas ntxiv lwm cov hlau rau kev lag luam Damascus riam cuam tshuam rau lawv cov hnav tsis kam
Feem ntau niaj hnub kev lag luamDamascus riamtsis yog tsuas yog tsim los ntawm high carbon steel; lawv kuj muaj lwm yam hlau hauv lawv, xws li chromium, molybdenum, vanadium, nickel, thiab lwm yam. Cov khoom no muaj kev cuam tshuam loj npaum li cas cov khoom tuav tau zoo.
Ntxiv chromium rau hlau tuaj yeem ua rau nws tiv taus corrosion thiab oxidation ntau dua. Qhov no txhais tau hais tias nws yuav tsis xeb yooj yim nyob rau hauv huab cua los yog kub kub, uas yuav pab kom cov hniav puas los ntawm corrosion. Molybdenum thiab vanadium tuaj yeem hloov pauv cov qauv nplej, ua rau cov hlau hnyav dua, thiab ua kom cov hniav ruaj khov thaum nws nyob hauv siab - kev sib txhuam ceev.
yog tias cov hlau zoo, nws yuav hnav sai dua yog tias nws tsis sov- kho. Feem ntau ntawm cov sij hawm, muaj riam phom Damascus yuav tsum tau mus txog quenching, tempering, thiab cryogenic kho.
cov hniav tuaj yeem nyuaj heev (HRC58-62 lossis siab dua) yog tias nws tau quenched kom zoo. Qhov no ua rau zoo rau kev txiav cov khoom hauv factories.
Muaj tseeb qib kev lag luam Damascus riam yog kim dua li cov riam niaj hnub vim tias lawv dhau los ntawm kev kho cua sov, uas raug nqi ntau heev. lawv kav ntev dua thiab muaj ntau dua resistant rau hnav.
2, Kev lag luam Damascus riam ua haujlwm zoo npaum li cas hauv lub neej tiag tiag
txiav cov ntawv hlau, yas zaj duab xis, cov khoom siv roj hmab, ntawv thiab cov khoom ntim, thiab lwm yam.Cov kev ua haujlwm no feem ntau muaj cov yam ntxwv hauv qab no: lawv tshwm sim ntau zaus, siv sijhawm ntev, thiab khiav txhua lub sijhawm. Qhov no txhais tau hais tias cov cuab yeej txiav yuav tsum muaj zog heev rau hnav. Cov neeg siv feem ntau hais tias Damascus riam kav ntev li 1.5 mus rau 3 zaug ntev dua li cov pa roj carbon hlau tsis tu ncua nyob rau hauv tib lub sijhawm. Qhov no txhais tau hais tias kev poob qis thiab kev hloov cuab yeej tshwm sim tsawg dua, uas txhim kho kev tsim khoom tag nrho.
Qhov zoo tshaj plaws ntawm Damascus riam piv rau lwm cov hniav yog tias lawv muaj "kev ua tau zoo sib npaug." Cov riam carbon steel ib txwm pheej yig tab sis hnav sai sai thiab tsuas yog zoo rau luv luv -lub sij hawm lossis siv lub teeb. Cov riam phom tawv tawv heev tiv taus hnav, tab sis lawv tsis tawv heev thiab tuaj yeem nti thaum lawv tsoo ib yam dab tsi. Kev lag luam Damascus riam tsoo qhov sib npaug zoo ntawm ob: nws tiv taus hnav thiab tsis yooj yim tawg, ua rau nws zoo rau kev nyuaj, tsis tu ncua, thiab siab -load ua hauj lwm tej yam kev mob.higher unit nqi, tab sis nws yog tiag tiag tus nqi ntau dua - siv tau nyob rau hauv lub sij hawm ntev vim hais tias nws xav tau tsawg dua cov cuab yeej hloov thiab nqi tsawg dua los tswj.
3, xaiv qhov zoo tshaj plaws kev lag luam Damascus riam uas yuav tsis hnav
muaj Damascus riam, koj yuav tsum xyuam xim rau peb yam: thawj yog cov ntaub ntawv siv los ua nws. Nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom tiag tiag uas qhia cov alloy muaj pes tsawg leeg thiab cov kev kho cua sov tsis zoo.Qhov thib ob yog daim ntawv thov kev mob, uas txhais tau hais tias ntau yam khoom txiav yuav tsum tau sib txawv ntawm cov hardness thiab toughness.third yog lub hom thiab qhov zoo ntawm kev ua haujlwm. High- cov neeg tsim khoom zoo muaj kev lav phib xaub ntxiv thaum nws los txog rau kev ruaj ntseg ntawm cov txheej txheem forging thiab kev kho cua sov.wear kuj zoo dua ntawm Damascus riam tuaj yeem ua tiav tag nrho yog tias cov ntaub ntawv, txheej txheem, thiab kev ua haujlwm zoo ib yam.
