Nzira dzekuongorora kuomarara kweRockwell Knoop naVickers dzealuminium nitride ceramics uye nzira dzekuongorora mabheyaringi esimbi anotenderera

1.Rockwell Knoop Vickers nzira yekuyedza kuomarara kwesimbi dzealuminium nitride
Sezvo zvinhu zveceramic zvine chimiro chakaoma, zvakaoma uye zvinoputsika, uye zvine purasitiki diki, nzira dzinowanzo shandiswa dzekuratidza kuomarara dzinosanganisira Vickers hardness, Knoop hardness uye Rockwell hardness. Shancai Company ine mhando dzakasiyana dzevanoedza kuomarara, ine bvunzo dzakasiyana dzehardness uye dzakasiyana-siyana dzine chekuita nekuomarara.
Zvinotevera zvinogona kushandiswa senzira yekutarisa:
GB/T 230.2 Kuedza Kuomarara kweZvinhu zvesimbi zveRockwell:
Kune zviyero zvakawanda zveRockwell zvekuomarara, uye zvinhu zveceramic zvinowanzoshandisa zviyero zveHRA kana HRC.
GB/T 4340.1-1999 Kuedza kuomarara kweMetal Vickers uye GB/T 18449.1-2001 Kuedza kuomarara kweMetal Knoop.
Nzira dzekuyera dzeKnoop neMicro-Vickers dzakafanana, musiyano uripo ndewemhando dzakasiyana dze indenter dzinoshandiswa.
Zvakakosha kuziva kuti nekuda kwehunhu hwakakosha hwechigadzirwa ichi, tinogona kubvisa maburi eVickers asina kukodzera zvichienderana nemamiriro eburi remaburi panguva yekuyerwa kuti tiwane data rakarurama.
2. Nzira dzekuedza mabheyaringi esimbi anotenderera
Zvichienderana nenzira dzekuyedza kuomarara kwezvikamu zvesimbi nesimbi isina ferrous zvakatsanangurwa muJB/T7361-2007, kune nzira dzakawanda dzekuyedza zvichienderana nemaitiro ebasa, dzese dzinogona kuyedzwa neShancai hardness tester:
1） Nzira yekuedza kuomarara kweVickers
Kazhinji, zvikamu zvesimbi dzakasimba pamusoro pechinhu zvinoedzwa nenzira yekuedza kuomarara kwechinhu chebasa cheVickers. Kutarisirwa kunofanira kupihwa pakupedzwa kwechinhu chebasa uye kusarudzwa kwesimba rekuedza.
2）Rockwell nzira yekuedza kuomarara
Miedzo yakawanda yeRockwell hardness inoitwa uchishandisa HRC scale. Shancai Rockwell hardness tester ine ruzivo rwemakore gumi nemashanu uye inogona kusangana nezvinodiwa zvese.
3） Nzira yekuedza kuomarara kweLeeb
Kuedza kuomarara kweLeeb kunogona kushandiswa pamabheyaringi akaiswa kana akaoma kupatsanura. Kunyatsorongeka kwayo pakuyera hakuna kunaka sekwemuongorori wesimba rebenchtop.
Mutemo uyu unonyanya kushanda pakuyedzwa kwekuoma kwezvikamu zvesimbi zvinotakura, zvikamu zvesimbi zvinonamirwa uye zvinodziya uye zvikamu zvesimbi zvinopera pamwe chete nezvisina ferrous metal bearing.
