Kubera ubukana bwa Vickers hamwe na microhardness test, inguni ya diyama ya indenter ikoreshwa mugupima ni imwe. Nigute abakiriya bagomba guhitamo ikizamini cya Vickers? Uyu munsi, nzasobanura muri make itandukaniro riri hagati yikizamini cya Vickers nikizamini cya microhardness.
Ingano yingero zingana Kugabana Vickers gukomera hamwe na microhardness igipimo cyipimisha
Vickers gukomera kwipimisha: imbaraga zo kugerageza F.≥49.03N cyangwa≥HV5
Umutwaro muto Vickers gukomera: imbaraga zo kugerageza 1.961N≤F <49.03N cyangwa HV0.2 ~ <HV5
Ikizamini cya Microhardness: imbaraga zo kugerageza 0.09807N≤F <1.96N cyangwa HV0.01 ~ HV0.2
Nigute dushobora guhitamo imbaraga zikwiye zo kugerageza?
Tugomba gukurikiza ihame rivuga ko uko indentation nini, niko arushaho kumenya neza agaciro ko gupima niba akazi kakozwe, kandi tugahitamo nkuko bikenewe, kuko uko indentasiyo ntoya, niko ikosa rinini ryo gupima uburebure bwa diagonal, bizatuma habaho kwiyongera kw'ikosa ry'agaciro gakomeye.
Imbaraga zipimisha za microhardness zipima muri rusange zifite ibikoresho: 0.098N (10gf), 0.245N (25gf), 0.49N (50gf), 0.98N (100gf), 1.96N (200gf), 2.94 (300gf), 4.90N (500gf), 9.80N (1000gf) (19.6N (2.0Kg))
Gukuza muri rusange bifite ibikoresho: inshuro 100 (kwitegereza), inshuro 400 (gupima)
Urwego rwikizamini cyikizamini cya Vickers rushobora kugabanywamo: 2.94N (0.3Kgf), 4.9N (0.5Kgf), 9.8N (1.0Kgf), 19.6N (2.0Kgf), 29.4N (3.0Kgf), 49.0N (5.0Kgf), 98.0N (30Kgf), 196N (20Kgf), 196N (50Kgf) (moderi zitandukanye zifite ibizamini byo kugerageza bitandukanye.)
Ibikoresho byo gukuza ni rusange: inshuro 100, inshuro 200
Ikigeragezo gikomeye cya Vickers cya Shandong Shancai / Laizhou Laihua Igikoresho cyo Kwipimisha kirashobora gukora ibizamini byo gukomera kubice byasuditswe cyangwa ahantu ho gusudira.
Ukurikije agaciro gapimye, agaciro k'impinduka zo gusudira hamwe na metallurgjiya zishobora kugenzurwa. Kurugero, gukomera cyane birashobora guterwa nubushyuhe bukabije mugihe cyo gusudira, mugihe ubukana buke cyane bushobora kwerekana gusudira bidahagije cyangwa ibibazo byubuziranenge bwibintu.
Sisitemu yo gupima ya Vickers izakora porogaramu yikizamini cyuzuye kandi yerekana kandi yandike ibisubizo bijyanye.
Kubisubizo byikizamini cyo gupima, raporo ishushanyije irashobora guhita ikorwa.
Ni ngombwa kumenya ko mugihe uhitamo agace gahagarariye?gusudira nkibizamini, menya neza ko kariya gace katagira imyenge, ibice cyangwa izindi nenge zishobora kugira ingaruka kubisubizo.
Niba ufite ikibazo kijyanye no kugenzura weld, wumve neza
