1. Gwiritsani ntchito njira ya Vickers hardness tester ya ma welded (Weld Vickers hardness test) njira:
Popeza microstructure ya olowa mbali ya kuwotcherera (wotcherera msoko) pa kuwotcherera adzasintha pa mapangidwe ndondomeko, zikhoza kupanga ofooka ulalo mu welded dongosolo.Kuuma kwa kuwotcherera kumatha kuwonetsa mwachindunji ngati kuwotcherera ndikoyenera.Ndiye Vickers kuuma Njira yoyendera ndi njira yomwe imathandiza kuyesa ubwino wa welds.Vickers hardness tester wa Laizhou Laihua Hardness Tester Factory amatha kuyesa kuuma pazigawo zowotcherera kapena zowotcherera.Mukamagwiritsa ntchito Vickers hardness tester kuyesa zida zowotcherera, zotsatirazi ziyenera kudziwidwa:
Kukhazikika kwachitsanzo: Tisanayambe kuyesa, timagaya weld kuti tiyesedwe kuti ikhale yosalala, yopanda oxide wosanjikiza, ming'alu ndi zolakwika zina.
Pakatikati pa mzere wowotcherera, tengani mfundo pamtunda wokhotakhota mamilimita 100 aliwonse kuti muyese.
Kusankha magulu osiyanasiyana oyesera kumabweretsa zotsatira zosiyanasiyana, choncho tiyenera kusankha mphamvu yoyesera yoyenera tisanayesedwe.
2. Momwe mungagwiritsire ntchito Vickers hardness tester (micro Vickers hardness tester) kuti muwone kuya kwa wosanjikiza?
Kodi mungazindikire bwanji kuya kwa gawo lolimba la zitsulo zokhala ndi chithandizo chapamwamba monga carburizing, nitriding, decarburization, carbonitriding, etc., ndi zitsulo zomwe zidazimitsidwa?
Kuzama kosanjikiza kogwira mtima kumagwiritsidwa ntchito kwambiri kutenthetsa m'deralo kuti apangitse kusintha kwamapangidwe ndi magwiridwe antchito pamtunda wachitsulo kuti akwaniritse zotsatira za kuuma kowonjezereka ndi mphamvu ndi kulimba.Zimatanthawuza muyeso kuchokera kumayendedwe oyima a gawolo kupita kumalire a microstructure omwe atchulidwa.Kapena mtunda wowumitsidwa wosanjikiza wa microhardness yotchulidwa.Nthawi zambiri timagwiritsa ntchito njira ya gradient hardness tester ya Vickers hardness tester kuti tizindikire kuya kwake kolimba kwa chogwiriracho.Mfundo yake ndikuzindikira kuya kolimba kolimba kutengera kusintha kwa kuuma kwa Micro-Vickers kuchokera pamwamba kupita pakati pa gawolo.
Panjira zinazake zogwirira ntchito, chonde onani vidiyo ya kampani yathu ya Vickers hardness tester.Zotsatirazi ndi zoyambira zosavuta:
Konzani chitsanzo monga momwe mukufunikira, ndipo malo oyesera ayenera kupukutidwa pagalasi.
Sankhani mphamvu yoyesera ya Vickers hardness tester.Kuuma kwa gradient kumayesedwa pawiri kapena kupitilira apo.Kuuma kwa Vickers kumayesedwa pamzere umodzi kapena zingapo zofananira pamtunda.
Kujambula kuuma kokhotakhota kutengera deta yoyezedwa, zitha kudziwika kuti mtunda wowongoka kuchokera pamwamba pa gawolo kupita ku 550HV (nthawi zambiri) ndiye kuzama kolimba kosanjikiza.
3. Momwe mungagwiritsire ntchito Vickers hardness tester poyesa kulimba kwa fracture (njira yoyezetsa kuuma kwa Vickers)?
Kulimba kwa fracture ndiko kukana komwe kumasonyezedwa ndi zinthu pamene chitsanzo kapena chigawocho chimasweka pansi pazifukwa zosakhazikika monga ming'alu kapena zowonongeka.
Kulimba kwa fracture kumayimira kuthekera kwazinthu kuteteza kufalikira kwa ming'alu ndipo ndi chizindikiro cha kulimba kwa chinthu.
Mukayesa kulimba kwa fracture, choyamba pukutani pamwamba pa chitsanzo choyesera pagalasi.Pa Vickers hardness tester, gwiritsani ntchito conical diamondi indenter ya Vickers hardness tester kuti mupange indentation pamtunda wopukutidwa ndi katundu wa 10Kg.Ming'alu yokonzedweratu imapangidwa pamizere inayi ya chizindikirocho.Nthawi zambiri timagwiritsa ntchito Vickers hardness tester kuti tipeze deta yolimba ya fracture.
