Chiyambi cha nyimbo zolimbitsa thupi
Kuumitsa kwapadera ndi muyeso woyimira magetsi okhudzana ndi Robert L. Smith ndi George E. Tsitsi lina lankhondo lolimbana ndi njira zoyeserera komanso brinelve.
Mfundo ya Vickers Hardness Oness:
Ma teckers hardness amagwiritsa ntchito katundu wa 49.03 ~ 980.7n kukanikiza diamondi yolumikizira ndi gawo la 136 ° kukhala pamwamba pa nkhaniyi. Atangoigwira kwa nthawi yodziwika, mtengo wolumikizidwa wa Vickers amawerengedwa ndikuyeza kutalika kwa diagonil.
Ntchito Zogwiritsira Ntchito Zapamwamba za Mitundu Itatu ya Vickers (Micro Vickers):
Makina owonera a Vickers omwe ali ndi katundu wa 49.03 ~ 980.7Nn ndi yoyenera kufalikira kwamitundu ikuluikulu yamiyala ikuluikulu.
Katundu wotsika kwambiri, mayeso oyeserera <1.949.03n, yoyenera kufalikira kwamitundu yochepa, malo a chida, kapena zokutira;
Micro Vickers Harness, kuyesa katundu <1.961N, yoyenera kukula kwa matope achitsulo ndi zigawo zowonda kwambiri.
Kuphatikiza apo, okhala ndi cholembera, imatha kuyeza kuuma kwa knoti kovuta komanso kovuta monga galasi, ma ceramic, agate, ndi miyala yamtengo wapatali.
Ubwino wa Vickers Harts Tester:
1. Njira yoyeserera ili ndi zitsulo zambiri, kuchokera ku zitsulo zopita ku Superhard Zitsulo, ndipo zimatha kupezeka, kuyambira pa mitengo yochepa mpaka itatu mpaka itatu.
2. Kuzindikira ndi kochepa ndipo sikuwononga ntchito, yomwe itha kugwiritsidwa ntchito pakuyenerera kwa zojambula zomwe sizingawonongeke pamwamba pa ntchitoyo
3. Chifukwa cha mphamvu yake yaying'ono yoyesa, mphamvu yoyeserera imatha kufika 10g, yomwe imatha kuwona zoonda zina zazing'ono komanso zazing'ono
Zovuta za ma vickers hareder:
Poyerekeza ndi njira zoyeserera za Brinell ndi zoyeserera, kuyesedwa kwa nyimbo za Vickers kuli ndi zofunikira zosemphana ndi malo ogwirira ntchito. Zojambula zina zimafuna kupukuta, komwe kuli nthawi yambiri komanso otanganidwa
Ma tester hardles owoneka bwino amakhala olondola ndipo sayenera kugwiritsa ntchito pantchito kapena pamalo, ndipo amagwiritsidwa ntchito kwambiri mu labotaries.
