1. Siv cov tes ntsuas kom nruj ntawm Welded Parts (Weld Vickers Hardness Test) Txoj Kev:
Txij li thaum microstructure ntawm kev sib koom ua ke ntawm weldment (weld seam (weld seam) thaum lub sij hawm vuam yuav hloov thaum lub sijhawm tsim qauv, nws yuav ua rau cov qauv tsis muaj zog hauv cov qauv welded. Lub hardness ntawm cov vuam yuav ncaj qha rau seb cov cuab yeej siv hlau yog qhov tsim nyog. Tom qab ntawd cov vickers hardness ib txoj kev tshuaj xyuas yog ib txoj kev uas pab ntsuas cov Welds zoo. Lub ntsuas ntsuas lub zog HARIKHU HARIHU LAHIHUA HARDENNE HARDERM tuaj yeem ua kom pom kev nyuaj ntawm welded ntu lossis chaw vuam. Thaum siv Vickers Hardness Tester los kuaj cov seem welded, cov xwm txheej hauv qab no yuav tsum tau sau tseg:
Flenness ntawm cov qauv: ua ntej kev sim, peb zom cov weld tau kuaj kom nws lub ntsej muag du, dawb ntawm txheej oxide, kab nrib pleb thiab lwm yam tsis xws luag.
Ntawm txoj kab nruab nrab ntawm cov kab hauv Weld, coj ib qho taw tes rau ntawm txoj kev nkhaus txhua 100 hli rau kev sim.
Xaiv cov tub rog sib txawv yuav ua rau muaj txiaj ntsig zoo, yog li peb yuav tsum xaiv cov quab yuam uas tsim nyog ua ntej kev sim.
2. Yuav ua li cas siv Vickers Hardness Tester (micro vickers hardness tester) los xyuas qhov tob ntawm hardened txheej?
Yuav ua li cas los xyuas qhov tob ntawm cov steel qhov chaw nrog kev kho cov steel nrog kev ua kom zoo li carburization, thiab lwm yam, thiab steel seem uas tau induction quenched?
Qhov zoo hardened txheej qhov tob yog tsuas yog siv rau cov qauv cua sov kom ua rau ua kom tiav cov nyhuv ntawm kev ua kom muaj zog zuj zus thiab muaj zog thiab muaj zog. Nws yog hais txog kev ntsuas los ntawm cov kev taw qhia ntsug ntawm ib feem saum npoo rau qhov muaj microstructure ciam. Lossis cov tawv tawv tawv nrug ntawm cov microhardness tshwj xeeb. Feem ntau peb siv cov client hardness txoj kev ntawm Vickers Hardness Tester los xyuas qhov tob tob tob ntawm lub workpiece. Lub hauv paus ntsiab lus yog txhawm rau txhawm rau ua tau zoo txheej qhov tob tob tob tob ntawm kev hloov pauv hauv lub micro-vickers hardness los ntawm qhov chaw rau nruab nrab ntawm ib feem.
Txog cov haujlwm hauv kev ua haujlwm tshwj xeeb, thov saib rau peb lub tuam txhab lub tuam txhab Vickers Hardness Teser ua haujlwm video. Cov hauv qab no yog kev ua haujlwm yooj yim:
Npaj cov qauv raws li yuav tsum tau, thiab kev kuaj cov npoo yuav tsum tau polished rau daim iav nto.
Xaiv lub zog quab yuam ntawm Vickers Tester Tester. Lub hardness gradient yog ntsuas ntawm ob lossis ntau qhov chaw. Lub vickers hardness yog ntsuas ntawm ib lossis ntau txoj kab sib txuas mus rau saum npoo.
Teeb duab nyuaj nkhaus raws li cov ntaub ntawv ntsuas, nws tuaj yeem paub tau tias qhov kev ntsuas ntsug los ntawm qhov chaw rau 550hv (feem ntau) yog qhov ua tau zoo txheej qhov tob.
3. Yuav ua li cas siv Vickers Hardness Teser rau Skture Toughness Kuaj (Fracture Toughness Vickers Kev Ntsuas Qhov Txuj Ci)?
Kev ua kom nruj yog cov txiaj ntsig tiv thaiv los ntawm cov khoom siv thaum cov hnoos qeev lossis cov khoom sib xyaw ua ke nyob rau hauv cov xwm txheej tsis ruaj khov xws li tawg.
Kev ua kom tsis txhob muaj peev xwm tiv thaiv cov khoom siv los tiv thaiv cov khoom tawg thiab yog qhov ntsuas qhov tseeb ntawm cov khoom siv.
Thaum ua cov pob txha lov tolearness, thawj Polish rau saum npoo ntawm cov ntsuas ntsuas rau daim iav nto. Ntawm Vickers Hardness Tester, siv lub pob zeb sib luag Prefabricated kab nrib pleb yog tsim ntawm plaub qhov chaw ntawm lub cim. Peb feem ntau siv vickers hardness teser kom tau cov ntaub ntawv nyuaj heev.
