Dab tsi yog qhov ntsuas kub rau kev kho cua sov ntawm cov hlau? Kev ua kom zoo hardness thiab kev nruj

Cov khoom siv kub cuam tshuam nrog cua sov cov khoom siv kub thiab kub ntxhov, thiab kev kub ntxhov, thiab kev kub ntxhov, thiab kev kub ntxhov rau cov khoom siv cua sov uas muaj kev tswj hwm thaum muaj kev tswj hwm lub zog, thiab Feem ntau cov xim yog qhov tempered nyob ib ncig ntawm ib ncig ntawm ib ncig ntawm ib ncig ntawm cov txiaj ntsig zoo tshaj plaws {} Kev kho oxygen kuj yuav tsum tau siv los txhim kho corrosion tsis kam {}}

Cov Ntsiab Lus Tseem Ceeb:
Dab tsi yog qhov ntsuas kub rau kev kho cua sov? Kev ua kom zoo hardness thiab kev nruj
Kub Ranges Rau Kev Kho Cua Sov:

Kev kho tshav kub cuam tshuam nrog cov hlau cua sov kom ua kom tau qhov kub thiab txias kom ua tiav cov khoom xav tau {}}
Tempering yog ib qho txheej txheem cua sov uas tshwm sim ntawm 350 degrees Fahrenheit thiab 1350 degrees Fahrenheit {2} {2}
Qhov no tau raug xaiv los txo cov brittleness thaum tswj kev sib npaug ntawm hardness thiab tawv .
Lub hom phiaj ntawm tempering:

Tempering tau ua tom qab quenching kom txo brittleness thiab txhim kho cov tawv nqaij thiab txhim kho kev ua kom nruj {}}
Cov Cuab Yeej Cua Sov Rau 450 Qib F yog feem ntau siv los ua tiav qhov siab tshaj plaws hardness thaum minimizing brittleness.
Cov tshwj xeeb kub nyob ntawm hom hlau thiab nws npaj siv .
Qhov cuam tshuam ntawm oxygen thaum kho cua sov:

Cov pa tuaj yeem muaj peev xwm muaj peev xwm muaj cov hlau hauv cov hlau los tsim hlau oxide (teev) uas cuam tshuam rau cov khoom zoo .
Nws tseem tuaj yeem ua rau cuam tshuam oxidrane hauv qhov chaw carburized, uas tsis muaj zog cov khoom .
Cov pa rov qab nrog cov pa roj carbon nyob rau saum npoo ntawm cov hlau, ua rau pom kev txiav txim siab saum npoo uas txo qhov nyuaj .
Tshuaj tswj hwm oxidation rau corrosion resistance:

Qee cov txheej txheem cua sov txhob txwm siv oxygen los tsim cov txheej txheem tswj cov oxide txheej, xws li cov txheej txheem tswj npoo oxide {}}
Cov txheej no tuaj yeem txhim khu corrosion tsis kam nyob rau hauv qee cov kev siv .
Tus txheej txheem no yuav tsum tau kho kom tsis txhob muaj kev tswj yuam kev ntawm kev poob siab lossis ntsuas in0.
Qhov tseem ceeb ntawm cov khoom siv tshwj xeeb:

Ntau hom hlau yuav tsum muaj kev kho cua sov me ntsis thiab cov txheej txheem .
Piv txwv li, cov pa roj carbon ntau yuav xav tau qhov temperating kub siab kom ua tiav qhov kev xav sib npaug ntawm hardness thiab tawv .
Nkag siab txog cov yam ntxwv tshwj xeeb ntawm cov hlau raug kho yog qhov tseem ceeb kom ua tiav qhov zoo tshaj plaws kev ua .
Cov tswv yim cuam tshuam rau cov khoom siv thiab cov neeg yuav khoom:

Thaum yuav cov cuab yeej kho cua sov, xyuas kom meej tias cov cuab yeej tuaj yeem ua tiav thiab tswj hwm qhov yuav tsum tau kub (E {}} kev kawm f) {{4 4}}
Xav Txog Qhov Xav Tau Rau Cov Tshuaj Tiv Thaiv (E {{{{} g {}, Txo Kev Tiv Thaiv Oxygen, Ntsuas .
Rau cov neeg muaj txiaj ntsig xws li kev tiv thaiv kev tiv thaiv lossis roj av, ntsuas seb puas muaj kev txhawb nqa oxidation lossis tiv thaiv kev tsis txaus siab thaum tshav kub {}}
Los ntawm kev nkag siab cov ntsiab lus no, khoom siv thiab cov neeg yuav khoom tuaj yeem ua rau lawv cov kev xav tau thiab ua tiav cov khoom xav tau thiab ua tiav cov khoom xav tau.}
