1 Ukulungiselela ngaphambi kovavanyo
1) Isivavanyeli sobulukhuni kunye ne-indenter esetyenziselwa uvavanyo lobulukhuni beVickers kufuneka ihambelane nemigaqo ye-GB/T4340.2;
2) Ubushushu begumbi ngokubanzi kufuneka bulawulwe ngaphakathi koluhlu lwe-10 ~ 35℃. Kwiimvavanyo ezineemfuno ezichanekileyo, kufuneka zilawulwe kwi (23±5)℃.
Iisampulu ezi-2
1) Umphezulu wesampuli kufuneka ube tyaba kwaye uthambile. Kucetyiswa ukuba uburhabaxa bomphezulu wesampuli buhlangabezane neemfuno: Ixabiso eliphezulu leparameter yoburhabaxa bomphezulu: Isampuli yobunzima beVickers 0.4 (Ra)/μm; isampuli yobunzima beVickers yomthwalo omncinci 0.2 (Ra)/μm; isampuli yobunzima beVickers encinci 0.1 (Ra)/μm
2) Kwiisampuli zeVickers ezincinci kunye neemicro Vickers, kucetyiswa ukuba ukhethe ukupholisha okufanelekileyo kunye nokupholisha nge-electrolytic ukuze kulungiswe umphezulu ngokweentlobo zezinto.
3) Ubukhulu besampulu okanye umaleko wovavanyo kufuneka bube buphindwe kayi-1.5 ubude be-diagonal yobude be-indentation
4) Xa usebenzisa umthwalo omncinci kunye nee-micro Vickers ukuvavanya, ukuba isampuli incinci kakhulu okanye ayilunganga, isampuli kufuneka ifakwe okanye ibotshelelwe ngento ekhethekileyo ngaphambi kokuvavanya.
3Indlela yovavanyo
1) Ukukhethwa kwamandla ovavanyo: Ngokobunzima, ubukhulu, ubungakanani, njl.njl. besampulu, amandla ovavanyo aboniswe kwiTheyibhile 4-10 kufuneka akhethwe kuvavanyo.
2) Ixesha lokufaka amandla ovavanyo: Ixesha ukususela ekuqaleni kokufaka amandla ukuya ekugqityweni kokufaka amandla ovavanyo olupheleleyo kufuneka libe phakathi kwemizuzwana emi-2 ukuya kwengama-10. Kwiimvavanyo zobunzima be-Vickers kunye ne-micro Vickers, isantya sokuhla kwe-indenter akufuneki sidlule kwi-0.2 mm/s. Ixesha lokubamba amandla ovavanyo yimizuzwana eli-10 ukuya kweli-15. Kwizinto ezithambileyo ngakumbi, ixesha lokubamba linokwandiswa, kodwa impazamo kufuneka ibe phakathi kwemizuzwana emi-2.
3) Umgama ukusuka embindini womngxunya ukuya kumphetho wesampuli: Iintsimbi, ubhedu kunye nee-alloys zobhedu kufuneka zibe bubude obuphindwe ka-2.5 ubude be-diagonal bomngxunya; iintsimbi ezikhanyayo, i-lead, i-tin kunye nee-alloys zazo kufuneka zibe bubude obuphindwe ka-3 ubude be-diagonal bomngxunya. Umgama phakathi kwamaziko ee-indenti ezimbini ezikufutshane: kwi-alloys zentsimbi, ubhedu kunye nobhedu, kufuneka zibe bubude obuphindwe ka-3 bomgca we-diagonal wophawu lokuma; kwi-alloys ezikhanyayo, i-lead, i-tin kunye nee-alloys zazo, kufuneka zibe bubude obuphindwe ka-6 bomgca we-diagonal womngxunya.
4) Linganisa i-avareji yezibalo zobude bee-diagonals ezimbini ze-indentation, uze ufumane ixabiso lobunzima beVickers ngokwetheyibhile, okanye ubale ixabiso lobunzima ngokwefomula.
Umahluko kubude bee-diagonals ezimbini ze-indentation kwi-plane akufuneki udlule i-5% yexabiso eliqhelekileyo lee-diagonals. Ukuba lidlula, kufuneka liphawulwe kwingxelo yovavanyo.
5) Xa kuvavanywa kwisampulu yomphezulu ogobileyo, iziphumo kufuneka zilungiswe ngokwetafile.
6) Ngokubanzi, kuyacetyiswa ukuba kuxelwe amaxabiso ovavanyo lobunzima bamanqaku amathathu kwisampulu nganye.
Udidi lwe-4 Vickers hardness tester
Kukho iintlobo ezimbini zeeVickers hardness testers ezisetyenziswa rhoqo. Oku kulandelayo sisandulela sokusetyenziswa kweeVickers hardness tester ezisetyenziswa rhoqo:
1. Uhlobo lokulinganisa i-eyepiece;
2. Uhlobo lokulinganisa isoftware
Udidi 1: Uhlobo lokulinganisa i-eyepiece Iimpawu: Sebenzisa i-eyepiece ukulinganisa. Ukusetyenziswa: Umatshini wenza i-inbot (yedayimani ◆), kwaye ubude be-diagonal bedayimani bulinganiswa nge-eyepiece ukuze kufunyanwe ixabiso lobunzima.
Udidi 2: Uhlobo lokulinganisa isoftware: Iimpawu: Sebenzisa isoftware yobunzima ukulinganisa; kulula kwaye kulula emehlweni; inokulinganisa ubunzima, ubude, igcine imifanekiso yokuqina, iingxelo zemiba, njl. Ukusetyenziswa: Umatshini wenza ukuqina (idayimani ◆), kwaye ikhamera yedijithali iqokelela ukuqina kwikhompyutha, kwaye ixabiso lobunzima lilinganiswa kwikhompyutha.
