Martensitic hlau, paub txog nws lub zog siab thiab Hardness, tau siv dav hauv kev lag luam xws li aerospace, thiab tsim tau. Txawm li cas los xij, nws muaj ntau yam zoo, Martensitic hlau nthuav tawm ntau cov kev cov nyom uas cov tsim nyog yuav tsum tau hais kom peb muaj peev xwm. Cov ntawv no tshawb txog cov teeb meem saum toj kawg nkaus uas cuam tshuam nrog Martensitic Steel thiab muab cov kev pom tswv yim rau cov tuam txhab tsom mus rau qhov ua kom zoo rau lawv cov khoom siv no.
1. Siab hardness thiab nkig xwm
Martensitic steel yog tus cwj pwm los ntawm kev tawv tawv siab, uas ua rau nws zoo tagnrho rau cov hnav -} Cov ntawv thov tiv taus. Txawm li cas los xij, qhov hardness no los nrog poob qis: cov khoom siv brittleness. Cov pa roj carbon ntau hauv Martensitic steel tuaj yeem ua rau nws tsis tshua tau tawg, tshwj xeeb tshaj yog thaum raug rau kev cuam tshuam sai heev lossis mob siab heev.
Kev daws:Kev kho cua sov kom zoo, suav nrog kev ua kom sov siab, tuaj yeem pab txo qis huv Brittleness los ntawm kev txo cov kev ntxhov siab sab hauv thaum khaws cov khoom siv tawv.
2. Nyuaj machinility
Vim nws lub hardness, Martensitic steel tuaj yeem nyuaj rau tshuab. Cov cuab yeej ib txwm txiav hnav tau sai sai, ua rau cov nqi tsim khoom nce ntxiv thiab siv sijhawm siv sijhawm ntev dua.
Kev daws:Siv cov cuab yeej txiav siab ua los ntawm high - Cov ntaub ntawv ua tau zoo, xws li carbide lossis ceramic, thiab ua kom zoo txiav machinability.
3. Thermal Paub Txog
Cov hlau sib tw yog rhiab rau qhov kub hloov, uas tuaj yeem ua rau muaj kev ncua tsis raug thiab hloov pauv hauv cov khoom siv neeg kho tshuab. Qhov tsis sib xws txias tus nqi thaum lub sijhawm kho cua sov lossis vuam vuam yuav ua rau muaj kev sib txawv lossis tawg.
Kev daws:Kev tswj hwm thiab niaj hnub txias cov hau kev, xws li roj quenching lossis cua txias, yog qhov tseem ceeb los tswj cov khoom siv ncaj ncees. Tsis tas li ntawd, preheating ua ntej vuam tuaj yeem tiv thaiv kom tsis txhob poob siab.
4. Corrosion Kuj Cov Teeb Meem
Txawm hais tias Steels yog muaj zog, lawv corrosion tsis kam yog feem ntau qis dua piv rau lwm hom ntawm stainless hlau. Qhov no yog qhov teeb meem tshwj xeeb hauv ib cheeb tsam uas noo noo lossis tshuaj lom neeg.
Kev daws:Txhawm rau txhim kho corrosion tsis kam, cov startensitic steels tuaj yeem sib txuam nrog cov ntsiab xws li cov chromium thiab molybdenum, lossis cov kev kho mob hauv qab xws li nitubation lossis passivation tuaj yeem ua haujlwm.
5. Weldability txoj kev sib tw
Vuam Martensitic Steel tuaj yeem ua teeb meem vim nws nyiam ua cov cua sov saws cua sov {}} cuam tshuam zones (hz). Qhov no tuaj yeem ua rau tawg los yog cov pob qij txha hauv welded pob qij txha, tshwj xeeb yog yog tsis tswj kom tau.
Kev daws:Preheating thiab tshaj tawm - Weld Kev Kho Mob Kub yog qhov tseem ceeb los txo qhov kev pheej hmoo ntawm kev tawg. Siv tsawg - hydrogen mabtomodes thiab tswj cov nqi cua txias kuj tseem tuaj yeem txhim kho weld zoo.
6. Kev kho cua sov nyuaj
Cov txheej txheem kev kho cua sov rau MARTENITATIC steel yog cov nyom thiab yuav tsum tau kho kom meej. Kev kho kom sov sov tuaj yeem ua rau tsis muaj zog, muaj cov microstruction, thiab cuam tshuam cov microstructures, tsis zoo cuam tshuam cov khoom ua haujlwm.
Kev daws:Kev siv hluav taws xob kub kho cua sov nrog kub kho kom haum thiab cov nqi txias txias tuaj yeem ua kom muaj xwm txheej. Kev xeem ib txwm siv thiab cov tshev ua tau zoo yog tsim nyog kom paub meej tias cov khoom muaj peev xwm yog nyob hauv kev qhia tshwj xeeb.
7. Microstructure excitivity
Martensitic steel txoj kev ua tau zoo yog hnyav nyob ntawm nws cov microstructure. Kev hloov pauv hauv cov ntsiab lus carbon, cov nqi cua txias, thiab cov khoom siv cua txias, tuaj yeem ua rau muaj kev sib txawv hauv cov khoom, xws li Hardness thiab tawv.
Kev daws:Cov khoom siv sib xws sourcing thiab ua tib zoo tswj ntawm txoj kev sib dhos yog qhov tseem ceeb. Tsis tas li ntawd, kev tshawb xyuas microstructure yog pab xyuas kom paub tseeb tias cov khoom ua raws cov lus qhia yam xav tau.
8. Cov Nqi Muaj Nqi Ntau Lawm
Cov nqi ntau lawm ntawm cov hlau martensitic yuav siab dua li ntawm lwm cov ntaub ntawv vim nws cov kev ua tiav. Qhov xav tau rau cov khoom siv tshwj xeeb, siab - cov ntaub ntawv raw, thiab meej cov txheej txheem kev kub ceev tuaj yeem nce cov nqi tag nrho.
Kev daws:Cov tuam txhab tsim nyog yuav tsum tsom rau cov txheej txheem ntau lawm, txo cov khoom pov tseg, thiab txhim kho kev siv tshuab los ntawm kev siv automation thiab lean kev tsim kho kom tsawg.
9. Post -} Kev Ua Tau
Tom qab machining lossis sib, martensitic steel feem ntau xav tau ntxiv tshaj tawm {{0 х} Ua cov kauj ruam saum npoo lossis txhim kho corrosion tsis kam.
Kev daws:Kev sib xyaw ua ke cov kev daws teeb meem xws li hauv -}} Kev Kho Mob Hauv Tsev Muaj peev xwm hloov cov txheej txheem tshwj xeeb hauv cov txheej txheem thiab txo qee lub sijhawm ua.
10. Kev sau ntawv
Txawm hais tias nws lub zog thiab hardness, martensitic steel yuav tsis haum rau txhua daim ntawv thov. Nws tsis muaj kev ua tau zoo thiab kev ua tsis zoo ntawm cov kub tsis muaj nws qhov zoo tshaj plaws rau cov khoom siv ua kom tiav rau kev thauj khoom lossis huab cua ib puag ncig.
Kev daws:Nkag siab txog qhov xav tau ntawm qhov kawg -} siv daim ntawv thov yog qhov tseem ceeb. Rau cov mob xav tau heev, cov chaw tsim khoom tuaj yeem xav txog cov hlau martensitic nrog lwm cov ntsiab lus lossis tshawb xyuas cov khoom siv uas muaj kev ntxhov siab zoo dua raws li kev ntxhov siab.
