Fasteners zvinhu zvakakosha zvemakinika yekubatanidza, uye kuoma kwavo mwero ndechimwe chezviratidzo zvakakosha kuyera kunaka kwavo.
Zvinoenderana neakasiyana ekuomarara nzira dzekuedza, Rockwell, Brinell uye Vickers kuomarara nzira dzekuyedza dzinogona kushandiswa kuyedza kuomarara kwezvisungo.
Iyo Vickers kuomarara bvunzo inoenderana neISO 6507-1, iyo Brinell kuomarara bvunzo inoenderana neISO 6506-1, uye Rockwell kuomarara bvunzo inoenderana neISO 6508-1.
Nhasi, ini ndichasuma iyo micro-Vickers kuomarara nzira yekuyera iyo yepasi decarburization uye kudzika kweiyo decarburized layer yezvisungo mushure mekupisa kupisa.
Kuti uwane ruzivo, ndapota tarisa kune iyo yenyika standard GB 244-87 yeyero yekuyera mirau pakadzika kweiyo decarburized layer.
Iyo micro-Vickers bvunzo nzira inoitwa zvinoenderana neGB/T 4340.1.
Sample inogaro gadzirirwa nesampling, kugaya nekupukuta, yozoiswa pamicro-hardness tester kuti ione chinhambwe kubva kumusoro kusvika pakasvika kukosha kwekuomarara kunodiwa.Iwo chaiwo mashandiro nhanho anotemerwa nechiyero che automation yehukukutu tester yakashandiswa chaizvo.
