Vickers hardness yog ib qho qauv rau kev qhia qhov hardness ntawm cov ntaub ntawv uas tau hais los ntawm British Robert L. Smith thiab George E. Sandland hauv 1921 ntawm Vickers Ltd.
1 Txoj Cai ntawm Vickers hardness tester:
Vickers hardness tester siv lub load ntawm 49.03 ~ 980.7N los nias lub khob hliav qab-zoo li pob zeb diamond intruder nrog lub kaum sab xis ntawm 136 ° ntawm cov khoom nto.Tom qab tuav nws rau lub sijhawm teev tseg, ntsuas qhov indentation diagonally.Kab ntev, thiab mam li xam Vickers hardness tus nqi raws li tus qauv.
2.Load daim ntawv thov ntau yam:
01: Vickers hardness tester nrog load ntawm 49.03 ~ 980.7N yog haum rau hardness ntsuas ntawm workpieces loj thiab tob txheej txheej;
02: Me me load Vickers hardness, kuaj load <1.949.03N, haum rau hardness ntsuas ntawm nyias workpieces, cuab tam nto los yog coatings;
03: Micro-Vickers hardness, kuaj load <1.961N, haum rau hardness ntsuas ntawm hlau foils thiab nyias nyias txheej txheej.
Tsis tas li ntawd, nruab nrog Knoop indenter, nws tuaj yeem ntsuas qhov Knoop hardness ntawm nkig thiab tawv cov ntaub ntawv xws li iav, ceramics, agate, thiab cov gemstones dag.
3 Qhov zoo ntawm Vickers hardness tester:
1) Kev ntsuas ntau yog dav, xws li cov hlau mos mus rau ultra-hardness testers mus rau super-hard hlau, thiab qhov kev ntsuas ntau ntawm ob peb mus rau peb txhiab Vickers hardness qhov tseem ceeb.
2) Lub indentation yog me me thiab tsis ua puas lub workpiece.Nws tuaj yeem siv rau kev sim hardness ntawm workpieces uas nws nto tsis tuaj yeem raug puas tsuaj.
3) Vim nws qhov kev sim me me, qhov ntsuas qhov tsawg kawg nkaus tuaj yeem ncav cuag 10g, yog li nws tuaj yeem ntes qee qhov nyias thiab me me workpieces.
4 Qhov tsis zoo ntawm Vickers hardness tester: Piv nrog Brinell thiab Rockwell hardness testing method, Vickers hardness test muaj qhov yuav tsum tau ua rau lub smoothness ntawm workpiece nto, thiab ib co workpieces yuav tsum tau polished, uas yog lub sij hawm-siv thiab siv zog heev;kev saib xyuas Lub hardness tester yog qhov tseeb thiab tsis haum rau siv hauv kev cob qhia lossis ntawm qhov chaw.Nws feem ntau yog siv hauv chav kuaj.
5 Vickers hardness tester series
