Hauv cov txheej txheem ua kom cov hlau nto muaj zog xws li carburizing, nitriding thiab induction quenching, kev sim ntawm qhov nyuaj ntawm lub hauv paus thiab qhov tob ntawm cov txheej tawv, nrog rau qhov tsis zoo ntawm cov txheej txheem kho cua sov, yuav cuam tshuam rau tag nrho cov khoom siv kho tshuab ntawm cov khoom. Peb siv lub tshuab ntsuas micro Vickers hardness los ua kom tiav tag nrho cov txheej txheem sim thiab tswj qhov tob ntawm cov txheej tawv, uas yog qhov tseem ceeb ntawm kev tswj xyuas zoo.
1. Kev Npaj Qauv
Xaiv qhov seem kuaj lossis tus qauv qauv thiab txiav qhov seem hla kom ntseeg tau tias qhov chaw kuaj yog tiaj tus, tsis muaj kev hloov pauv thiab tsis muaj burr.
· Sib tsoo thiab txhuam qhov seem hla kom tshem tawm cov txheej oxide saum npoo thiab cov cim tshuab.
· Txiav raws li cov qauv tsim nyog (yog tias tsim nyog) kom paub meej tias txheej saum npoo ntawm lub hauv paus tseem ceeb sib txawv.
2. Kev Ntsuas Qhov Nyuaj Siab ntawm Core
Peb siv Model MHV-1000AT micro Vickers hardness tester los ua kom tiav tag nrho cov txheej txheem xeem.
· Muab cov qauv tso rau ntawm theem ntawm lub Micro Vickers hardness tester thiab teeb tsa nws rau thaj chaw tseem ceeb (deb ntawm txheej tawv tawv).
Teem lub zog sim (feem ntau HV1.0) thiab lub sijhawm nyob, thiab paub tseeb tias cov khoom siv tau calibrated kom raug.
Xaiv 3 txog 5 qhov ntsuas sib xws ntawm lub hauv paus, zam kev puas tsuaj xws li porosity, qhov cua thiab cov khoom sib xyaw.
· Pib ntsuas; cov nqi hardness raug nyeem tau yam tsis tas siv neeg, thiab tus nqi nruab nrab raug coj los ua qhov kawg ntawm qhov hardness ntawm lub hauv paus.
3. Kev Ntsuas Qhov Tob Ntawm Cov Txheej Uas Tau Khoov
· Teem cov ntsiab lus sim ntawm qhov sib npaug zos raws txoj kab ncaj nraim ntawm qhov chaw mus rau lub hauv paus, thiab teeb tsa qhov deb ntawm cov kauj ruam raws li cov qauv tsim nyog (feem ntau yog 10–50 μm).
Ntsuas qhov nyuaj ib qho zuj zus, thiab sau cov nqi nyuaj thiab qhov tob sib xws ntawm txhua qhov chaw.
Txuas ntxiv ntsuas kom txog thaum qhov nyuaj ruaj khov qis dua qhov tseem ceeb, tom qab ntawd tsum qhov kev sim.
4. Kev Txiav Txim Siab Txog Qhov Tob Ntawm Cov Txheej Uas Tau Kho Kom Zoo (CHD)
· Txheeb xyuas qhov tseem ceeb ntawm qhov nyuaj raws li cov qauv sib xws (piv txwv li, GB / T 9450).
· Nrhiav qhov chaw uas qhov nyuaj thawj zaug poob rau qhov tseem ceeb; qhov tob no yog txhais tias yog qhov tob ntawm cov txheej tawv.
5. Kev Ua Cov Ntaub Ntawv thiab Kev Tshaj Tawm
· Kos daim duab qhia txog qhov nyuaj faib tawm nrog qhov tob ua kab rov tav thiab qhov nyuaj ua kab ntsug los qhia qhov nyuaj gradient.
· Npaj cov ntaub ntawv suav nrog qhov nyuaj ntawm lub hauv paus, qhov tob ntawm txheej tawv thiab qhov nkhaus tawv kom tsim tau daim ntawv qhia kev xeem.
Kev ntsuam xyuas qhov nyuaj thiab qhov tob saum toj no yog ua los ntawm
Q-80Z tshuab txiav metallographic
MP-2000 tsis siv neeg metallogtaphic sib tsoo thiab polishing tshuab
MHV-1000AT micro Vickers hardness tester
Yog tias koj xav paub ntxiv txog lawv thov nias qhov nias sib xws hauv cov khoom lag luam.
