Vickers hardness yog tus qauv rau kev qhia txog qhov nyuaj ntawm cov ntaub ntawv uas tau hais los ntawm British Robert L. Smith thiab George E. Sandland hauv xyoo 1921 ntawm Vickers Ltd. Qhov no yog lwm txoj kev sim hardness tom qab Rockwell hardness thiab Brinell hardness testing methods.
1. Lub hauv paus ntsiab lus ntawm Vickers hardness tester:
Lub Vickers hardness tester siv lub nra hnyav ntawm 49.03 ~ 980.7N los nias lub pob zeb diamond cone-puab nrog lub kaum sab xis ntawm 136 ° ntawm qhov chaw ntawm cov khoom. Tom qab tswj nws rau lub sijhawm teev tseg, ntsuas qhov indentation diagonally. Qhov ntev ntawm kab, thiab tom qab ntawd xam Vickers hardness tus nqi raws li cov mis.
2. Load daim ntawv thov ntau yam:
01: Lub Vickers hardness tester nrog lub nra hnyav ntawm 49.03 ~ 980.7N yog qhov tsim nyog rau kev ntsuas qhov nyuaj ntawm cov workpieces loj dua thiab cov khaubncaws sab nraud povtseg tob dua;
02: Lub nra hnyav me me Vickers hardness, kev sim load <1.949.03N, tsim nyog rau kev ntsuas qhov nyuaj ntawm cov khoom ua haujlwm nyias nyias, cov cuab yeej nto lossis cov txheej txheem;
03: Micro-Vickers hardness, test load <1.961N, tsim nyog rau kev ntsuas qhov nyuaj ntawm cov hlau foils thiab cov txheej txheem nyias nyias heev.
Tsis tas li ntawd xwb, nws muaj lub cuab yeej ntsuas Knoop indenter, nws tuaj yeem ntsuas qhov nyuaj ntawm Knoop ntawm cov khoom siv tawg yooj yim thiab tawv xws li iav, ceramics, agate, thiab cov pob zeb cuav.
3 Qhov Zoo ntawm Vickers hardness tester:
1) Qhov ntsuas ntau yam yog dav, xws li cov hlau mos mus rau cov khoom siv kuaj ultra-hardness mus rau cov hlau super-hard, thiab qhov ntsuas ntau yam yog txij li ob peb mus rau peb txhiab Vickers hardness tus nqi.
2) Qhov indentation me me thiab tsis ua rau lub workpiece puas tsuaj. Nws tuaj yeem siv rau kev sim qhov nyuaj ntawm cov workpieces uas qhov chaw tsis tuaj yeem puas tsuaj.
3) Vim nws lub zog me me, lub zog tsawg kawg nkaus tuaj yeem ncav cuag 10g, yog li nws tuaj yeem ntes tau qee qhov workpieces nyias thiab me me.
4 Qhov tsis zoo ntawm Vickers hardness tester: Piv nrog Brinell thiab Rockwell hardness testing methods, Vickers hardness test muaj qhov yuav tsum tau rau qhov du ntawm qhov chaw ua haujlwm, thiab qee qhov workpieces yuav tsum tau polished, uas yog siv sijhawm thiab siv zog ntau; kev txij nkawm Lub hardness tester yog qhov tseeb thiab tsis haum rau kev siv hauv cov chaw ua haujlwm lossis hauv chaw. Nws feem ntau yog siv hauv cov chaw soj nstuam.
5 Vickers hardness tester series
1) Kev ntsuas Vickers hardness pheej yig
2) Cov zaub digital kov npo Vickers hardness tester
3) Lub tshuab ntsuas Vickers hardness tag nrho
