Kuumitsa kwapadera ndi muyezo wofotokozera kuuma kwa zinthu zomwe zidafunidwa ndi Brith Robert Lt. Slithge E. Ichi ndi njira ina yoyeserera yoyeserera njira zoyeserera.
Mfundo 1 ya Vickers Harder:
Ma teckers handeness amagwiritsa ntchito katundu wa 49.03 ~ 980.7n kuti akakakanikizire ma cereser a cungu owoneka bwino ndi 136 ° pazinthu. Atakhalabe ndi nthawi yodziwika, yesetsani kuthana ndi vuto. Kutalika kwa mzere, kenako kuwerengera mtengo wovuta malinga ndi mawonekedwe.
2. Kwezani ntchito:
01: Woyimba molimba mtima ndi katundu wa 49.03 ~ 980.7Nn ndi yoyenera kufalikira kwamitundu ikuluikulu yamiyala ikuluikulu;
02: Mayeso ang'onoang'ono owombera, kuyesa katundu <1.949.03n, yoyenera kufalikira kwamitundu yopyapyala, pachida champhamvu kapena zokutira;
03: 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.
3 Ubwino wa Vickers Hardness Onecy:
1) Kufananira kwake kuli kochulukirapo, kuyambira pazitsulo zofewa kupita ku ma trates ogwirira ntchito ku zitsulo zapamwamba, ndipo muyeso wofanana ndi mikhalidwe yocheperako mpaka 3,000.
2) Kuzindikira ndikochepa ndipo sikuwononga ntchito yogwira ntchito. Itha kugwiritsidwa ntchito pakuyesa kwamitundu yomwe imatha kuwonongeka.
3) Chifukwa cha mphamvu yake yaying'ono, mphamvu yochepera ingafikire 10g, kotero imatha kuwona ntchito zazing'ono komanso zazing'ono.
4 Zoyipa za Mavalidwe a Vickers Haster: Poyerekeza ndi njira za Brinell ndi Kuyeserera kwa Ruckerde ali ndi zofunikira za malo osungirako malowo, ndipo zomangamanga zina zimayenera kupukutidwa, zomwe zimagwiritsidwa ntchito kwambiri komanso nthawi yayitali kwambiri; kukonza tester yolimba imakhala yotsimikizika ndipo sioyenera kugwiritsa ntchito mumisonkhano kapena pamalopo. Amagwiritsidwa ntchito kwambiri mu labotaries.
5 ma vickers hardness tester
1) chuma chambiri
2) digito yowonetsera digito
3) Zovala zokwanira mavalidwe
