Na te pakeke o Vickers me te whakamatautau microhardness, he rite tonu te koki taimana o te indenter e whakamahia ana mo te ine. Me pehea te whiriwhiri a nga kaihoko i te whakamatautau pakeke Vickers? I tenei ra, ka whakaahua poto ahau i te rereketanga i waenga i te whakamatautau pakeke Vickers me te whakamatautau microhardness.
Whakamātautau wehenga rahi kaha Vickers pakeke me te microhardness tauine whakamātautau
Vickers te whakamaarama pakeke: te kaha whakamatautau F≥49.03N ranei≥HV5
Uta iti Vickers pakeke: kaha whakamatautau 1.961N≤F <49.03N ranei HV0.2 ~ < HV5
Kaiwhakamatau Microhardness: kaha whakamatautau 0.09807N≤F <1.96N ranei HV0.01 ~ HV0.2
Na me pehea e whiriwhiri ai i te kaha whakamatautau tika?
Me whai tatou i te kaupapa ko te nui ake o te nuku, ka tika ake te ine ine mena ka whakaaetia e nga tikanga mahi, me te whiriwhiri i nga mea e hiahiatia ana, no te mea ko te iti o te nuku, ka nui ake te hapa i te ine i te roa hauroki, ka piki ake te hapa o te uara pakeke.
Ko te kaha whakamatautau o te kaiwhakamaori moroiti kei te nuinga o te waa: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.90N, 4.90N. (1000gf) (19.6N (2.0Kgf) hei kōwhiri)
Ko te whakanui i te nuinga o te waa: 100 nga wa (matakitaki), 400 nga wa (ine)
Ko te taumata kaha whakamatautau o te Vickers pakeke tester ka taea te wehewehe ki: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kgf), 49.0N (5.0Kgf), 49.0N (5.0Kgf), 49.0N (5.0Kgf), 49.0N (5.0Kgf). 196N (20Kgf), 294N (30Kgf), 490N (50Kgf) (he rereke nga whirihoranga kaha o nga tauira rereke.)
Ko te whirihoranga whakanui ko te tikanga: 100 nga wa, 200 nga wa
Ka taea e te Vickers te whakamaarama pakeke o Shandong Shancai/Laizhou Laihua Whakamatau Taonga Whakamātautau te mahi i nga whakamatautau pakeke i runga i nga waahanga paiherea, i nga waahi whakapiri ranei.
E ai ki te uara pakeke ine, ka taea te whakatau i te kounga o te weld me nga huringa whakarewa. Hei tauira, he nui rawa te pakeke na te nui o te wera i te wa e whakapiri ana, engari ko te iti rawa o te pakeke ka tohu i te kore rawa o te whakapiri, i te raru o te kounga rauemi.
Ko te punaha inenga Vickers kua whirihorahia ka whakahaere i tetahi kaupapa whakamatautau aunoa me te whakaatu me te tuhi i nga hua e rite ana.
Mo nga hua o te whakamatautau ine, ka taea te whakaputa aunoa i te purongo whakairoiro.
He mea nui kia mohio koe i te wa e whiriwhiri ana i tetahi waahi tohu o'Ko te weld hei waahi whakamatautau, me whakarite kia kore he pores o tenei waahi, he kapiti me etahi atu koha ka pa ki nga hua whakamatautau.
