Qhov sib txawv ntawm Vickers hardness tester thiab microhardness tester

Vim yog Vickers hardness thiab microhardness test, lub pob zeb diamond kaum ntawm lub indenter siv rau kev ntsuas yog tib yam. Yuav ua li cas cov neeg muas zaub xaiv Vickers hardness tester? Hnub no, kuv yuav piav luv luv txog qhov sib txawv ntawm Vickers hardness tester thiab microhardness tester.

Test quab yuam loj faib Vickers hardness thiab microhardness tester nplai

Vickers hardness tester: xeem quab yuam F≥49.03n ib≥HV 5

Me me load Vickers hardness: xeem quab yuam 1.961N≤F < 49.03N or HV0.2 ~ < HV5

Microhardness tester: xeem quab yuam 0.09807N≤F < 1.96N lossis HV0.01 ~ HV0.2

Yog li cas peb yuav tsum xaiv lub zog xeem uas tsim nyog?

Peb yuav tsum ua raws li lub hauv paus ntsiab lus uas qhov loj dua qhov indentation, qhov tseeb dua qhov ntsuas tus nqi yog tias lub workpiece tej yam kev mob tso cai, thiab xaiv raws li qhov xav tau, vim tias qhov me me ntawm qhov indentation, qhov yuam kev ntau dua hauv kev ntsuas qhov ntev ntawm kab pheeb ces kaum, uas yuav ua rau muaj qhov yuam kev ntawm cov nqi hardness.

Kev ntsuas lub zog ntawm microhardness tester feem ntau yog nruab nrog: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.90g (1000gf) (19.6N (2.0Kgf) yeem)

Lub magnification feem ntau yog nruab nrog: 100 zaug (saib), 400 zaug (kev ntsuas)

Kev ntsuas lub zog ntawm Vickers hardness tester tuaj yeem muab faib ua: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kgf), 49.0N (5.0Kgf), 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (cov qauv sib txawv muaj qhov sib txawv ntawm qhov ntsuas qhov sib txawv.)

Cov kev teeb tsa magnification feem ntau yog: 100 zaug, 200 zaug

Vickers hardness tester ntawm Shandong Shancai / Laizhou Laihua Testing Instrument tuaj yeem ua qhov kev sim hardness ntawm qhov chaw welded lossis qhov chaw vuam.

Raws li qhov ntsuas hardness tus nqi, qhov zoo ntawm qhov vuam thiab metallurgical hloov tuaj yeem txiav txim siab. Piv txwv li, lub hardness siab dhau lawm yuav yog vim muaj cua sov ntau dhau thaum lub sij hawm vuam, thaum lub hardness tsawg dhau yuav qhia tau tias vuam tsis txaus lossis cov khoom tsis zoo.

Lub Vickers kev ntsuas qhov system yuav khiav ib qho kev xeem tsis siv neeg tag nrho thiab tso saib thiab sau cov txiaj ntsig sib xws.

Rau cov txiaj ntsig ntawm kev ntsuas ntsuas, daim ntawv tshaj tawm cov duab sib thooj tuaj yeem raug tsim tawm.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum xaiv ib qho chaw sawv cev ntawmualub vuam raws li qhov ntsuas qhov ntsuas, xyuas kom meej tias thaj chaw no tsis muaj qhov pores, tawg lossis lwm yam tsis xws luag uas yuav cuam tshuam rau qhov kev xeem.
