Njengoko sonke sisazi, indlela nganye yokuvavanya ubulukhuni, nokuba yiBrinell, Rockwell, Vickers okanye i-portable Leeb hardness tester, inemida yayo kwaye ayinamandla onke. Kwizinto zokusebenza ezinkulu, ezinzima nezingaqhelekanga zejometri ezifana nale iboniswe kumzekelo olandelayo, iindlela ezininzi zokuvavanya zangoku zisebenzisa i-portable Leeb hardness testers ukulawula ubulukhuni bazo.
Indlela yokulinganisa eguquguqukayo yesivavanyi sobunzima beLeeb inezinto ezininzi ezichaphazela ukuchaneka kwayo kobunzima: ezinje: i-modulus ye-elastic yezinto ezibonakalayo, ukusetyenziswa kwentloko yebhola, uburhabaxa bomphezulu we-workpiece, i-curvature radius, ubunzulu bomaleko obuqinileyo, njl. Xa kuthelekiswa neendlela zokulinganisa ezingashukumiyo zikaBrinell, Rockwell kunye noVickers, impazamo inkulu kakhulu. Ukuba ubunzima bufuna ukuchaneka okuphezulu, singayikhetha njani isivavanyi sobunzima?
Olu hlobo lomsebenzi onzima kwinkqubo yovavanyo oluqhelekileyo lovavanyo lobunzima, ngaphambi kokuba uvavanyo lulayishe kwaye lukhuphe umvavanyi wobunzima, kunye nokukhupha umvavanyi wobunzima kuya kuzisa umthwalo omkhulu womsebenzi kwinkqubo yokusebenza, ngoko ke sikhetha njani umvavanyi wobunzima? Oku kulandelayo kucebisa ukusetyenziswa komvavanyi wobunzima onesakhiwo sokuphakamisa intloko ukugqiba yonke inkqubo yovavanyo. Njengoko kubonisiwe ngezantsi:
Esi sisombululo sovavanyo lobunzima sinokufezekisa uvavanyo lobunzima beRockwell/Vickers kunye novavanyo lobunzima beBrinell ngokwemigangatho yovavanyo lobunzima (GB/T 231.1, GB/T 4340.1, ISO6507, ISO6508, ASTM E18, njl.njl.), kwaye sihlangabezane neemfuno zovavanyo oluchanekileyo kunye nemveliso esebenzayo yezinto ezinzima.
Umvavanyi wobunzima bokuphakamisa intloko ngokuzenzekelayo unebhentshi yokusebenzela esisigxina, enciphisa impazamo ebangelwa sisikrufu kunye nokuphakanyiswa kwebhentshi yokusebenzela ukuya kumgangatho ochanekileyo wokulinganisa ubunzima. Ibhentshi yokusebenzela inkulu ngobukhulu kwaye inokwamkela izinto zokusebenza ezinkulu ezinobunzima. Ukulinganisa ngeqhosha elinye kunciphisa kakhulu impazamo yovavanyo kunye nomsebenzi womvavanyi, nto leyo elula kwaye ikhawuleza.
