Rockwell Nab thiab Vickers Hardness Testing txoj kev rau Aluminium Nitride Ceramics thiab Kev Ntsuas Rau Hlau Dov Bearings

1.Rhowell Knoop Vickers Hardness Tet Edit txoj kev rau Aluminium Nitride Ceramics
Txij li thaum cov ntaub ntawv ceramic muaj cov qauv nyuaj, yog qhov nyuaj thiab muaj cov txheej txheem hardness me me, thiab muaj lub hardness feem ntau, lub pob zeb hardness thiab rockwell hardness. Lub tuam txhab Shancai muaj ntau cov kev ntaus pob hardness, nrog cov kev ntsuas nyuaj thiab ntau cov khoom siv tawv tawv.
Cov qauv hauv qab no tuaj yeem siv raws li siv:
GB / T 230.2 Muamic Cov Khoom Siv Rockwell Hardness:
Muaj ntau ntau lub rockwell hardness dos, thiab tej hub ntaub ntawv feem ntau siv HRC lossis HRC NPLAI.
GB / T 4340.1-1999 Hlau Vickers Hardness Kuaj Thiab GB / T 18449.1-2001 Hlau Knoop Hardness Test.
Cov kev ntsuas thiab micro-vickers ntsuas kev ntsuas yog qhov sib txawv, qhov sib txawv yog qhov sib txawv uas siv.
Nws yog tsim nyog sau tseg tias vim qhov tshwj xeeb ntawm cov khoom, peb tuaj yeem tshem tawm cov neeg tsis muaj qhov tsis muaj tseeb raws li lub xeev ntawm kev ntsuas kom tau txais cov ntaub ntawv ntau dua.
2.Testing txoj kev rau hlau rolling bearings
Raws li cov txheej txheem ntsuas nyuaj rau cov hlau thiab tsis muaj ntau txoj hauv kev ua haujlwm raws li cov txheej txheem ua haujlwm, txhua tus tuaj yeem kuaj nrog Sharanai Hardness Tester:
1) Vickers Hardness Testing Txoj Kev
Feem ntau, saum npoo av tawv yog sim los ntawm Vickers Hardness Testing txoj kev. Saib xyuas yuav tsum tau them rau saum npoo ua tiav ntawm workpiece thiab xaiv ntawm kev sim quab yuam.
2) Rockwell Hardness Testing txoj kev
Feem ntau cov kev ntsuam xyuas pob zeb pob zeb ua haujlwm tau ua siv HRC nplai. Shancai rockwell hardness tester tau sau 15 xyoo ntawm kev paub thiab tuaj yeem sib ntsib txhua qhov kev xav tau.
3) Leeb hardness txoj kev
Lub haub hardness ntsuas tuaj yeem siv rau cov kabmob uas tau nruab lossis nyuaj rau disassemble. Nws ntsuas ntsuas qhov tseeb tsis yog qhov zoo li qhov ntawm lub chaw muag khoom tawv.
Cov qauv no feem ntau yog siv rau lub hardness ntsuas ntawm cov kabmob hlau, annealed thiab ua tiav cov kabmob uas tsis muaj hlau cov kabmob.
