Rockwell Knoop uye Vickers kuomarara nzira dzekuyedza dzealuminium nitride ceramics uye nzira dzekuyedza dzesimbi inotenderedza mabheji.

1.Rockwell Knoop Vickers kuoma kwekuedza nzira yealuminium nitride ceramics
Sezvo zvinhu zveceramic zvine chimiro chakaomarara, chakaoma uye chine brittle muzvisikwa, uye zvine madiki epurasitiki deformation, iyo inowanzoshandiswa kuomarara nzira dzekutaura dzinosanganisira Vickers kuomarara, Knoop kuomarara uye Rockwell kuomarara. Shancai Kambani ine akasiyana siyana ekuomarara testers, ine akasiyana bvunzo yekuomarara uye akasiyana ane chekuita nekuomarara testers.
Aya mazinga anotevera anogona kushandiswa sereferensi:
GB/T 230.2 Metallic Materials Rockwell Hardness Test:
Kune akawanda Rockwell kuomarara zviyero, uye zvinhu zveceramic zvinowanzo shandisa HRA kana HRC zviyero.
GB/T 4340.1-1999 Metal Vickers kuoma bvunzo uye GB/T 18449.1-2001 Metal Knoop kuoma bvunzo.
Iyo Knoop neMicro-Vickers yekuyera nzira dzakafanana, mutsauko ndiwo akasiyana indenters anoshandiswa.
Zvakakosha kucherechedza kuti nekuda kwechimiro chakakosha chechigadzirwa, tinogona kubvisa zvisizvo Vickers indentations zvinoenderana nemamiriro eiyo indentation panguva yekuyera kuti tiwane data rakawanda.
2.Test nzira dzesimbi inokungurutsa mabheya
Zvinoenderana nekuoma kwekuomarara nzira dzesimbi uye dzisiri simbi inotakura zvikamu zvakatsanangurwa muJB/T7361-2007, kune dzakawanda nzira dzekuyedza zvinoenderana neiyo workpiece maitiro, ese anogona kuyedzwa neShancai hardness tester:
1）Vickers kuomarara nzira yekuyedza
Kazhinji, nzvimbo dzakaomeswa dzekutakura dzinoedzwa neVickers kuomarara nzira yekuyedza. Kuchenjerera kunofanira kubhadharwa kumucheto wepamusoro we workpiece uye kusarudzwa kwesimba rekuedza.
2）Rockwell kuomarara nzira yekuyedza
Yakawanda Rockwell kuomarara bvunzo dzinoitwa uchishandisa HRC chiyero. Shancai Rockwell hardness tester akaunganidza makore gumi nemashanu echiitiko uye anogona kuzadzisa zvese zvinodiwa.
3）Leeb kuomarara nzira yekuyedza
Muyedzo wekuoma kweLeeb unogona kushandiswa kumabhengi akaiswa kana kunetsa kupatsanura. Kuyera kwayo kuyerwa hakuna kunaka senge yebenchtop hardness tester.
Iyi chiyero inonyanya kushanda kune kuomarara bvunzo yesimbi inotakura zvikamu, annealed uye hasha dzinotakura zvikamu uye dzakapedzwa kutakura zvikamu pamwe neasina-ferrous simbi inotakura zvikamu.
