Cov txheej txheem kuaj mob Rockwell Knoop thiab Vickers rau cov khoom siv ceramics txhuas nitride thiab cov txheej txheem kuaj rau cov kabmob hlau dov

1. Txoj kev ntsuas qhov nyuaj ntawm Rockwell Knoop Vickers rau cov khoom siv nitride txhuas
Vim tias cov ntaub ntawv ceramic muaj cov qauv nyuaj, tawv thiab tawg yooj yim, thiab muaj cov yas me me deformation, cov txheej txheem qhia txog qhov nyuaj feem ntau suav nrog Vickers hardness, Knoop hardness thiab Rockwell hardness. Shancai Company muaj ntau yam kev sim qhov nyuaj, nrog rau kev sim qhov nyuaj sib txawv thiab ntau yam kev sim qhov nyuaj cuam tshuam.
Cov qauv hauv qab no siv tau ua piv txwv:
GB/T 230.2 Cov Khoom Siv Hlau Rockwell Hardness Test:
Muaj ntau yam Rockwell hardness scales, thiab cov ntaub ntawv ceramic feem ntau siv HRA lossis HRC scales.
GB/T 4340.1-1999 Kev xeem hlau Vickers hardness thiab GB/T 18449.1-2001 Kev xeem hlau Knoop hardness.
Cov txheej txheem ntsuas Knoop thiab Micro-Vickers yeej zoo ib yam, qhov txawv yog cov indenters sib txawv siv.
Nws yog ib qho tsim nyog sau tseg tias vim yog qhov tshwj xeeb ntawm cov khoom, peb tuaj yeem tshem tawm cov Vickers indentations tsis raug raws li lub xeev ntawm indentation thaum lub sijhawm ntsuas kom tau txais cov ntaub ntawv tseeb dua.
2. Cov txheej txheem sim rau cov hlau dov bearings
Raws li cov txheej txheem kuaj qhov nyuaj rau cov hlau thiab cov hlau tsis yog ferrous uas tau teev tseg hauv JB / T7361-2007, muaj ntau txoj kev kuaj raws li cov txheej txheem ua haujlwm, txhua yam tuaj yeem kuaj nrog lub tshuab ntsuas qhov nyuaj Shancai:
1) Txoj kev ntsuas qhov nyuaj ntawm Vickers
Feem ntau, cov khoom siv uas tawv ntawm qhov chaw raug kuaj los ntawm txoj kev kuaj Vickers hardness. Yuav tsum tau saib xyuas qhov tiav ntawm qhov chaw ua haujlwm thiab kev xaiv lub zog kuaj.
2) Txoj kev kuaj mob Rockwell hardness
Feem ntau cov kev ntsuam xyuas Rockwell hardness yog ua los ntawm kev siv HRC nplai. Shancai Rockwell hardness tester tau sau 15 xyoo ntawm kev paub thiab tuaj yeem ua tau raws li txhua yam kev xav tau.
3） Txoj kev ntsuas qhov nyuaj ntawm Leeb
Qhov kev ntsuas qhov nyuaj ntawm Leeb siv tau rau cov bearings uas tau teeb tsa lossis nyuaj rau disassemble. Nws qhov kev ntsuas qhov tseeb tsis zoo li qhov ntawm lub tshuab ntsuas qhov nyuaj ntawm lub rooj zaum.
Tus qauv no feem ntau siv rau kev sim qhov nyuaj ntawm cov khoom siv hlau, cov khoom siv annealed thiab tempered thiab cov khoom siv tiav lawm nrog rau cov khoom siv hlau uas tsis yog ferrous.
