Nazi izinto zokusebenza ezithunyelwe ngumthengi ukuze kuvavanywe ubulukhuni bokugquma.
Ekubeni ubukhulu bengubo budla ngokuba buncinci kakhulu kwaye bulinganiswa ngee-micrometer, kunzima ukufumana amaxabiso achanekileyo obulukhuni ngeendlela eziqhelekileyo. Ke ngoko, indlela yovavanyo lobulukhuni be-micro Vickers idla ngokusetyenziswa xa kulinganiswa ubulukhuni bengubo, ngokubanzi ibonakaliswa yi-HV.
Njengoko umaleko wokugquma ubhityile kakhulu, ukulinganisa ubulukhuni ngqo kwingubo kuyingxaki. Izinto ezisetyenziswa phantsi komhlaba okanye ungqimba olungaphantsi ziya kuphazamisana neziphumo zovavanyo lobulukhuni. Ngaphambi kokuvavanya, silungisa izinto zokusebenza zibe ziisampuli eziqhelekileyo size emva koko senze uhlolo lobulukhuni.
I. Inkqubo yoLungiselelo lweeMpawu
Ukuthatha isampuli:Isampuli yokugquma isikwa ngesixhobo sokufaka i-metallographic ukuqinisekisa ukuba icandelo elinqamlezileyo liqulathe ngokupheleleyo umaleko wokugquma kunye nezinto ezisisiseko ze-substrate.
Ukufakelwa:Sebenzisa i-metallographic mounting press ukufaka isampuli ukuthintela ukudilika komphetho kunye nokuqhekeka kwengubo.
Ukusila nokupolisha:Gaya isampuli inyathelo ngenyathelo ukusuka kwiphepha lesanti elirhabaxa ukuya kwiphepha lesanti elincinci, uze uyipolish nge-metallographicukugayaumatshini wokupolisha ude ungabi nandawo yokukrwela, umda phakathi kwengubo kunye nesiseko ucacile, kwaye akukho maleko okhubazekileyo oseleyo.
II.Inkqubo yoVavanyo loBulukhuni
Sisebenzisa isixhobo sokuvavanya ubunzima seVickers esingezantsi esixhotyiswe ngenkqubo yokulinganisa ngokuzenzekelayo yokuvavanya.
Beka isampuli elungisiweyo ngokuthe chu kwitafile yokusebenza yesivavanyi sobunzima kunye necandelo elinqamlezileyo lengubo elijonge phezulu. Lungisa isampuli ngobunono ngebhloko yokucinezela ukuqinisekisa ukuba ayishukumi kwaye ayithambeki.
III.Inkqubo yoVavanyo
Ukugxila ngesandla (Ukhetho lweModeli yokugxila ngokuzenzekelayo)
Lungisa ngesandla indawo ekugxilwe kuyo isixhobo ukuze sibonise ngokucacileyo ubume bomphezulu wesixhobo somsebenzi kwi-interface yekhompyutha.
Qalisa Umlinganiselo
Seta indlela yokulinganisa kwikhompyutha uze ucofe uQala ukuze uqalise inkqubo yovavanyo.
Ukulayisha Ukuzibopha Okuzenzekelayo
Esi sixhobo sisebenzisa ngokuzenzekelayo amandla ovavanyo abekwe → ukubamba okuhlala → ukukhupha izinto, size senze ukuxinana kweVickers okumile okwedayimani.
Ukulinganisa Ukuzibopha Okuzenzekelayo
Ilensi ichonga ngokuzenzekelayo ubude obujikelezayo bokutsalwa, kwaye inkqubo ibala ngokuzenzekelayo ixabiso le-Vickers hardness HV.
Ukubalwa koBungqingqwa bokugquma
Misela indawo yojongano phakathi kwengubo kunye ne-substrate, kwaye isoftware ibala ngokuzenzekelayo.
Ukuba unomdla kwezi zixhobo zokulungiselela iisampulu kunye novavanyo lobunzima be-micro Vickers, nceda ubone uluhlu lweemveliso kwaye uzive ukhululekile ukunxibelelana nathi ukuze ufunde okungakumbi ngazo.
