I-9H isho ubulukhuni bese i-9D isho ukugoba kolwelwesi.
Kodwa ayikho i-9D yangempela, kungakhathaliseki ukuthi mangaki amafilimu e-D tempered ahlukaniswe kuphela ama-curvature amathathu: indiza, i-2.5D, ne-3D.
I-9H ibhekisela ebulukhunini, empeleni obubhekisela ebukhuni bepensela, hhayi ubulukhuni be-Mohs.Ngisho nocezu lwengilazi lungadlula lobu bunzima, obuphinde bube yi-gimmick yokumaketha.
Ukuqina kuhlukaniswe:
1. Ukuqina kokuqina.Ngokuyinhloko isetshenziselwa ukuqhathanisa izinga lokuthambile nobulukhuni bamaminerali ahlukene.Indlela yokukhetha induku enomkhawulo owodwa oqinile futhi enye ithambile kwenye, bese unwaya impahla ehloliwe eduze kwenduku, futhi unqume ukuthambile nokuqina kwempahla ehloliwe ngokuya ngokuma kokuklwebheka.Uma sikhuluma ngokufaneleka, imihuzuko eyenziwa izinto eziqinile mide, futhi imihuzuko eyenziwa izinto ezithambile mifishane.
2. Ukuqina kokucindezela.Ikakhulukazi esetshenziselwa izinto zensimbi, indlela yokucindezela i-indenter ecacisiwe ezintweni ezihloliwe ngomthwalo othile, futhi uqhathanise ubulukhuni bezinto ezihloliwe nosayizi we-deformation yepulasitiki yendawo ebusweni bento.
Ngenxa yomehluko we-indenter, ubude bomthwalo nomthwalo, kunezinhlobo eziningi zokuqina kokuhlehlisa, ikakhulukazi ukuqina kwe-Brinell, ukuqina kwe-Rockwell, ubulukhuni be-Vickers kanye nokuqina okuncane.
3. Ukubopha kabusha ubulukhuni.Ikakhulukazi esetshenziselwa izinto zensimbi, indlela yokwenza isando esincane esikhethekile siwe ngokukhululekile ukusuka ekuphakameni okuthile ukuze sibe nomthelela kusampula yezinto ezizohlolwa, futhi sisebenzise inani lamandla obunzima agcinwe (bese ekhululwa) yisampula ngesikhathi sokuhlolwa. inqubo yomthelela (ngokubuya kwesando esincane).jump height determination) ukunquma ubulukhuni bento.
Indlela yokuhlola ubulukhuni be-Rockwell yi-SP yaseMelika Ephakanyiswe ngu-Rockwell ngo-1919, inqoba ngokuyisisekelo ukushiyeka okukhulunywe ngenhla kokuhlolwa kwe-Brinell.I-indenter esetshenziselwa ubulukhuni be-Rockwell iyikhoni yedayimane ene-taper angle engu-120° noma ibhola lensimbi elinobubanzi obuyi-intshi engu-1/16 (intshi engu-1 ilingana no-25.4 mm), futhi ukujula kokuhlehlisa kusetshenziswa njengesisekelo sokulinganisa ubulukhuni. inani.
