Keeb kwm ntawm Vickers hardness tester
Vickers hardness yog ib qho qauv rau sawv cev rau cov khoom hardness uas tau thov los ntawm Robert L. Smith thiab George E. Sandland hauv 1921 ntawm Vickers Ltd.
Lub hauv paus ntsiab lus ntawm Vickers hardness tester:
Vickers hardness tester siv lub load ntawm 49.03 ~ 980.7N los nias lub pob zeb diamond square conical nrog lub kaum sab xis ntawm 136 ° rau saum npoo ntawm cov khoom.Tom qab tuav nws rau lub sijhawm teev tseg, Vickers hardness tus nqi yog xam los ntawm kev ntsuas qhov ntev ntawm kab pheeb ces kaum ntawm indentation thiab siv tus qauv.
Daim ntawv thov thauj khoom ntawm peb hom Vickers hauv qab no (micro Vickers):
Vickers hardness tester nrog load ntawm 49.03 ~ 980.7N yog haum rau hardness ntsuas ntawm workpieces loj thiab tob txheej txheej.
Tsawg load Vickers hardness, kuaj load <1.949.03N, haum rau hardness ntsuas ntawm thinner workpieces, cuab yeej nto, los yog coatings;
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.
Qhov zoo ntawm Vickers hardness tester:
1. Kev ntsuas ntau yog dav, los ntawm software hlau mus rau superhard hlau, thiab tuaj yeem kuaj pom, xws li ob peb mus rau peb txhiab Vickers hardness qhov tseem ceeb.
2. Lub indentation yog me me thiab tsis ua puas lub workpiece, uas yuav siv tau rau hardness kuaj ntawm workpieces uas tsis tuaj yeem ua puas rau ntawm qhov chaw ntawm lub workpiece.
3. Vim nws qhov kev sim me me, qhov ntsuas qhov tsawg kawg nkaus tuaj yeem ncav cuag 10g, uas tuaj yeem ntes qee qhov nyias thiab me me workpieces
Qhov tsis zoo ntawm Vickers hardness tester:
Piv nrog rau Brinell thiab Rockwell hardness kuaj txoj kev, Vickers hardness test muaj qhov yuav tsum tau rau qhov smoothness ntawm workpiece.Qee lub workpieces xav tau polishing, uas yog siv sijhawm ntev thiab siv zog ntau
Vickers hardness testers yog qhov tseeb thiab tsis haum rau siv hauv kev cob qhia lossis ntawm qhov chaw, thiab feem ntau yog siv hauv chav kuaj.
Shandong Shancai Vickers hardness tester series (daim duab rau Wang Songxin)
1. Economic Vickers hardness tester
2. Cov zaub thiab kov npo Vickers hardness tester
3. Tsis siv neeg Vickers hardness tester tag nrho
