1 Kev npaj ua ntej kuaj
1) Lub hardness tester thiab indenter siv rau Vickers hardness kuaj yuav tsum ua raws li cov kev cai ntawm GB / T4340.2;
2) Cov chav tsev kub yuav tsum tau tswj nyob rau hauv qhov ntau ntawm 10 ~ 35 ℃. Rau kev ntsuam xyuas nrog cov kev xav tau siab dua, nws yuav tsum tau tswj ntawm (23 ± 5) ℃.
2 Cov qauv
1) Cov qauv saum npoo yuav tsum tiaj tus thiab du. Nws raug pom zoo tias cov qauv saum npoo roughness yuav tsum ua kom tau raws li qhov yuav tsum tau muaj: Qhov siab tshaj plaws ntawm qhov roughness parameter: Vickers hardness qauv 0.4 (Ra) / μm; me me load Vickers hardness qauv 0.2 (Ra) / μm; micro Vickers hardness qauv 0.1 (Ra) / μm
2) Rau cov khoom me me Vickers thiab micro Vickers kuaj, nws raug nquahu kom xaiv cov polishing tsim nyog thiab electrolytic polishing rau kev kho deg raws li cov khoom siv.
3) Lub thickness ntawm cov qauv los yog cov txheej txheem xeem yuav tsum yog tsawg kawg yog 1.5 npaug ntawm kab pheeb ces kaum ntev ntawm qhov indentation
4) Thaum siv cov khoom me me thiab micro Vickers rau kev sim, yog tias cov qauv me me los yog tsis sib xws, cov qauv yuav tsum tau muab tso rau hauv lossis clamped nrog cov khoom tshwj xeeb ua ntej kuaj.
3Kev sim
1) Kev xaiv ntawm kev xeem quab yuam: Raws li qhov hardness, thickness, loj, thiab lwm yam ntawm cov qauv, qhov kev xeem quab yuam nyob rau hauv Table 4-10 yuav tsum tau xaiv rau qhov kev xeem. .
2) Test force application time: Lub sij hawm txij thaum pib ntawm kev siv quab yuam mus rau kev ua tiav ntawm daim ntawv thov quab yuam tag nrho yuav tsum tsis pub dhau 2 ~ 10 s. Rau me me load Vickers thiab micro Vickers hardness tests, lub indenter descending ceev yuav tsum tsis txhob ntau tshaj 0.2 mm / s. Lub sijhawm ntsuas lub zog tuav yog 10 ~ 15 s. Rau cov khoom muag tshwj xeeb, lub sijhawm tuav tuaj yeem txuas ntxiv, tab sis qhov yuam kev yuav tsum tsis pub dhau 2.
3) Kev ncua deb ntawm qhov chaw ntawm qhov indentation mus rau ntug ntawm cov qauv: Hlau, tooj liab thiab tooj liab alloys yuav tsum yog tsawg kawg yog 2.5 npaug ntawm kab pheeb ces kaum ntev ntawm qhov indentation; lub teeb hlau, txhuas, tin thiab lawv cov alloys yuav tsum yog tsawg kawg 3 zaug ntawm kab pheeb ces kaum ntawm qhov indentation. Qhov kev ncua deb ntawm qhov chaw ntawm ob qhov chaw nyob ib sab: rau cov hlau, tooj liab thiab tooj liab alloys, nws yuav tsum yog tsawg kawg 3 npaug ntawm qhov ntev ntawm kab kab pheeb ces kaum ntawm lub cim nres; rau lub teeb hlau, txhuas, tin thiab lawv cov alloys, nws yuav tsum yog tsawg kawg yog 6 npaug ntawm qhov ntev ntawm kab pheeb ces kaum ntawm qhov indentation.
4) Ntsuas tus lej lej ntawm qhov ntev ntawm ob kab pheeb ces kaum ntawm qhov indentation, thiab nrhiav Vickers hardness tus nqi raws li lub rooj, lossis xam tus nqi hardness raws li tus qauv.
Qhov sib txawv ntawm qhov ntev ntawm ob kab pheeb ces kaum ntawm qhov indentation ntawm lub dav hlau yuav tsum tsis pub tshaj 5% ntawm qhov nruab nrab tus nqi ntawm cov kab pheeb ces kaum. Yog tias nws dhau lawm, nws yuav tsum tau sau tseg hauv daim ntawv xeem.
5) Thaum kuaj ntawm tus qauv nkhaus, cov txiaj ntsig yuav tsum raug kho raws li lub rooj.
6) Feem ntau, nws raug pom zoo kom tshaj tawm qhov hardness test qhov tseem ceeb ntawm peb lub ntsiab lus rau txhua tus qauv.
4 Vickers hardness tester faib
Muaj 2 hom kev siv Vickers hardness testers. Cov hauv qab no yog kev qhia txog kev siv Vickers hardness tester uas nquag siv:
1. Hom ntsuas qhov muag;
2. Software ntsuas hom
Classification 1: Eyepiece ntsuas hom Nta: Siv eyepiece los ntsuas. Kev Siv: Lub tshuab ua ib qho (pob zeb diamond ◆) indentation, thiab kab pheeb ces kaum ntev ntawm lub pob zeb diamond yog ntsuas nrog lub ntsej muag kom tau txais tus nqi hardness.
Classification 2: Software ntsuas hom: Nta: Siv hardness software los ntsuas; yooj yim thiab yooj yim ntawm qhov muag; tuaj yeem ntsuas qhov hardness, ntev, txuag cov duab indentation, cov ntawv ceeb toom, thiab lwm yam.
