Txoj kev kuaj Vickers hardness thiab kev ceev faj

1 Kev npaj ua ntej kev sim

1) Lub tshuab ntsuas qhov nyuaj thiab lub tshuab ntsuas qhov nyuaj siv rau kev ntsuas qhov nyuaj ntawm Vickers yuav tsum ua raws li cov kev cai ntawm GB / T4340.2;

2) Feem ntau, qhov kub ntawm chav tsev yuav tsum tswj tau hauv qhov ntau ntawm 10 ~ 35 ℃. Rau kev sim nrog qhov yuav tsum tau ua kom raug dua, nws yuav tsum tswj tau ntawm (23 ± 5) ℃.

2 Cov Qauv

1) Qhov chaw ntawm cov qauv yuav tsum tiaj thiab du. Nws raug pom zoo tias qhov roughness ntawm qhov chaw ntawm cov qauv yuav tsum ua tau raws li qhov yuav tsum tau ua: Tus nqi siab tshaj plaws ntawm qhov roughness parameter: Vickers hardness qauv 0.4 (Ra) / μm; me me Vickers hardness qauv 0.2 (Ra) / μm; micro Vickers hardness qauv 0.1 (Ra) / μm

2) Rau cov qauv me me Vickers thiab micro Vickers, nws raug pom zoo kom xaiv cov polishing thiab electrolytic polishing rau kev kho qhov chaw raws li hom khoom siv.

3) Qhov tuab ntawm cov qauv lossis txheej xeem yuav tsum yog tsawg kawg yog 1.5 npaug ntawm qhov ntev ntawm kab pheeb ces kaum ntawm qhov nkag.

4) Thaum siv cov khoom me me thiab micro Vickers rau kev sim, yog tias cov qauv me me lossis tsis xwm yeem, cov qauv yuav tsum tau muab tso rau hauv lossis clamped nrog lub cuab yeej tshwj xeeb ua ntej sim.

3Txoj kev sim

1) Kev xaiv lub zog sim: Raws li qhov nyuaj, tuab, qhov loj, thiab lwm yam ntawm cov qauv, lub zog sim uas tau qhia hauv Rooj 4-10 yuav tsum tau xaiv rau qhov kev sim.

2) Lub sijhawm siv zog sim: Lub sijhawm txij li thaum pib siv zog mus txog rau thaum ua tiav tag nrho kev siv zog sim yuav tsum tsis pub dhau 2 ~ 10 vib nas this. Rau kev ntsuas qhov nyuaj ntawm Vickers thiab micro Vickers me me, qhov ceev ntawm indenter yuav tsum tsis pub tshaj 0.2 hli / s. Lub sijhawm tuav lub zog sim yog 10 ~ 15 vib nas this. Rau cov ntaub ntawv mos mos, lub sijhawm tuav tuaj yeem ntev dua, tab sis qhov yuam kev yuav tsum tsis pub dhau 2.

3) Qhov deb ntawm qhov chaw nruab nrab ntawm qhov nkag mus rau ntug ntawm cov qauv: Cov hlau, tooj liab thiab cov hlau sib xyaw ua ke yuav tsum muaj tsawg kawg yog 2.5 npaug ntawm qhov ntev ntawm qhov nkag; cov hlau sib dua, txhuas, tin thiab lawv cov hlau sib xyaw ua ke yuav tsum muaj tsawg kawg yog 3 npaug ntawm qhov ntev ntawm qhov nkag. Qhov deb ntawm qhov chaw nruab nrab ntawm ob qhov nkag uas nyob ib sab: rau cov hlau, tooj liab thiab cov hlau sib xyaw ua ke, nws yuav tsum muaj tsawg kawg yog 3 npaug ntawm qhov ntev ntawm kab pheeb ces kaum ntawm lub cim nres; rau cov hlau sib dua, txhuas, tin thiab lawv cov hlau sib xyaw ua ke, nws yuav tsum muaj tsawg kawg yog 6 npaug ntawm qhov ntev ntawm kab pheeb ces kaum ntawm qhov nkag.

4) Ntsuas qhov nruab nrab ntawm qhov ntev ntawm ob lub kab pheeb ces kaum ntawm qhov indentation, thiab nrhiav tus nqi Vickers hardness raws li lub rooj, lossis xam tus nqi hardness raws li cov mis.

Qhov sib txawv ntawm qhov ntev ntawm ob lub kab pheeb ces kaum ntawm qhov indentation ntawm lub dav hlau yuav tsum tsis pub tshaj 5% ntawm tus nqi nruab nrab ntawm cov kab pheeb ces kaum. Yog tias nws tshaj, nws yuav tsum tau sau tseg hauv daim ntawv qhia kev xeem.

5) Thaum kuaj ntawm qhov chaw nkhaus, cov txiaj ntsig yuav tsum tau kho raws li lub rooj.

6) Feem ntau, nws raug pom zoo kom tshaj tawm cov nqi xeem tawv ntawm peb lub ntsiab lus rau txhua tus qauv.

4 Vickers hardness tester kev faib tawm

Muaj 2 hom Vickers hardness testers uas siv ntau. Cov hauv qab no yog kev qhia txog kev siv Vickers hardness tester uas siv ntau:
