Umvavanyi wobulukhuni be-Universal ngokwenene zizixhobo zovavanyo ezipheleleyo ezisekelwe kwimigangatho ye-ISO kunye ne-ASTM, evumela abasebenzisi ukuba benze uvavanyo lobunzima beRockwell, Vickers kunye neBrinell kwizixhobo ezifanayo. Umvavanyi wobulukhuni be-universal uvavanywa ngokusekelwe kwimigaqo yeRockwell, Brinell, kunye neVickers endaweni yokusebenzisa ubudlelwane bokuguqulwa kwenkqubo yobunzima ukufumana amaxabiso amaninzi obulukhuni.
Izikali ezintathu zobunzima ezifanelekileyo zokulinganisa izinto zokusebenza
Isikali sobunzima be-HB Brinell sifanelekile ukulinganisa ubunzima besinyithi esityhidiweyo, ii-alloys ezingezizo iintsimbi, kunye neentsimbi ezahlukeneyo ezifakwe isinyithi neziqinisiweyo. Asifanelekanga ukulinganisa iisampulu okanye izinto zokusebenza eziqinileyo kakhulu, ezincinci kakhulu, ezincinci kakhulu, kwaye ezingavumeli ukuxinana okukhulu kumphezulu.
Isikali sobulukhuni se-HR Rockwell sifanelekile: ukulinganisa ubulukhuni bovavanyo lweenkuni, ukucima, ukucima kunye nokushisa iindawo eziphathwe ngobushushu.
Isikali sobulukhuni se-HV Vickers sifanelekile ukulinganisa ubulukhuni beesampuli kunye neenxalenye ezineendawo ezincinci kunye namaxabiso aphezulu obulukhuni, ubulukhuni beeleya ezifakwe ngaphakathi okanye iingubo emva konyango oluhlukeneyo lomphezulu, kunye nobulukhuni bezinto ezincinci.
Uluhlu olutsha lwabavavanyi bobulukhuni bendalo yonke
Yahlukile kwi-universal hardness tester yesiqhelo: i-universal hardness tester yesizukulwana esitsha isebenzisa iteknoloji ye-force sensor kunye nenkqubo yempendulo yamandla evaliweyo ukuze ithathe indawo yemodeli yokulawula ukulayisha ubunzima, okwenza umlinganiselo ube lula kwaye ixabiso elilinganisiweyo lizinze ngakumbi.
Idigri yokuzikhethela yokwenza izinto ngokuzenzekelayo: uhlobo lokuphakamisa oluzenzekelayo lwentloko yomatshini, uhlobo lokubonisa isikrini sedijithali, uhlobo lokulinganisa ikhompyutha
