Dab tsi yog kev kho cua sov? Txhim kho cov hlau zog, hardness thiab tawv

Kev kho cua sov yog cov txheej txheem tseem ceeb hauv cov hlau cov khoom siv hluav taws xob, ua kom muaj zog, nrog rau cov hlau, titanium, thiab tooj liab alloys, txhawm rau txhim kho kev hnav Kuj, lub peev xwm, thiab tag nrho cov kev ua haujlwm zoo siab (ua kom muaj kev lag luam sab hauv Brittleness . yog li ntawd, tempering yog feem ntau yuav tsum tau sib npaug cov yam ntxwv no.

Cov Ntsiab Lus Tseem Ceeb:
Dab tsi yog kev kho cua sov? Txhim kho cov hlau zog, tawv tawv, thiab tawv
Lub ntsiab lus thiab lub hom phiaj ntawm kev kho cua sov:

Kev kho cua sov cuam tshuam nrog cua sov thiab cua txias cov cuab tam los hloov lawv cov khoom .
Nws lub hom phiaj tseem ceeb yog txhawm rau txhim kho cov khoom siv cov khoom siv, xws li lub zog, hardness, thiab hnav tsis kam .
Hom Kev Kho Cua Sov:

Cov ntaub ntawv hardening: hamens tsuas yog saum npoo ntawm cov hlau, tawm hauv cov tseem ceeb ntawm cov mos mos .
Los ntawm kev tawv tawv: hardens tag nrho cov tuab ntawm cov hlau .
Annaling: muag cov hlau los txhim kho machinability lossis ductility .
Tempering: Tom qab quenching, nws tuaj yeem txo brittleness thiab txhim kho cov tawv nqaij thiab txhim kho cov tawv nqaij.
Kev Kho Tshav Kub Kub:

Cov cua cua sov: cua sov cov hlau rau ib qho kub tshwj xeeb kom hloov nws cov microstructure .
Kev tswj kom txias: Tus nqi ntawm kev txias txias (quenching, cua txias, thiab lwm yam}) txiav txim siab cov khoom kawg ntawm cov hlau.
Diffusion thiab microstructure: Cua sov kho mob hloov pauv doms tus nqi thiab cov khoom siv ntawm cov khoom siv tawv me xws li hardness thiab lub zog .
Txhim Kho Cov Khoom Siv Neeg Kho Tshuab:

Lub zog: ua kom muaj zog los ntawm cov txheej txheem quenching ua rau cov hlau tsis tshua tiv taus deformation {}}
Hardness: Kev kho cua sov txhim kho cov coj tsis kam ntawm cov hlau .
Kev nyuaj: Tempering: nce nyuaj los ntawm tempering cov nyiaj tshuav nyuaj nrog lub peev xwm los nqus lub zog yam tsis muaj lub zog tawg yam tsis muaj lub zog tawg yam tsis muaj lub zog tawg yam tsis muaj tawg .
Ductility: Kev siv dag zog: ntxiv dag zog los ntawm annealing ua rau cov hlau yooj yim dua los tsim lossis tshuab .
Kev lag luam tawm hauv kev kho cua sov:

Lub zog vs . tox nyuaj: ua kom muaj zog (muaj zog) txo cov hlau ntau dua {}}
Tempering: Kev kho cua sov yog qhov tsim nyog tom qab quenching kom txo cov brittleness thiab ua tiav qhov kev xav tshuav ntawm lub zog thiab tawv.
Cov ntawv thov ntawm kev kho cua sov:

Manufacturity: kev kho cua sov tuaj yeem ua rau muaj kev ntxhov siab sab hauv, ua cov hlau ua kom tiav yooj yim lossis khoov .
Hnav Kuj: Cov ntaub ntawv Hardening: Cov ntaub ntawv Hardening feem ntau siv rau cov seem uas xav tau ib qho nyuaj saum npoo kom tiv thaiv kev hnav thaum tswj hwm lub zog nyuaj {}}
Durability: hardening yog siv rau cov seem uas xav tau tag nrho cov qauv kom muaj zog thiab ruaj .
Khoom haum rau kev kho cua sov:

Steel: feem ntau kub kho kom nce lub zog thiab hardness .
Titanium: Kev kho tshav kub kom nce lub zog thiab corrosion tsis kam .
Cov roj cig liab alloys: kev kho tshav kub kom hnav tsis kam thiab durability.
Inconel: Kev kho tshav kub kom ua rau muaj kev kub kub siab thiab xeb tsis kam .
Cov Txheej Txheem Kawm:

Kev tswj qhov kub thiab txias: Kev tswj cov cua sov thiab cua txias yog qhov tseem ceeb kom ua tiav cov khoom xav tau {}}
Quenching nruab nrab: kev xaiv ntawm quenching nruab nrab (roj, dej, huab cua) tuaj yeem cuam tshuam cov nqi cua txias thiab cov khoom kawg {}}
Tempering kub: qhov kub thiab ntev thiab ntev yog qhov tseem ceeb rau kev ua tiav qhov kev sib npaug kom zoo ntawm hardness thiab tawv .
Hauv cov ntsiab lus, kev kho cua sov yog qhov muaj ntau yam thiab cov txheej txheem tsim tawm, lub zog ua kom pom cov khoom siv cua sov thiab kev ua kom zoo dua qub kom ua tiav {}}
