1. Sebenzisa indlela yokuhlola ubulukhuni be-Vickers yezingxenye ezihlanganisiwe (indlela yokuhlola ubulukhuni be-Weld Vickers):
Njengoba isakhiwo esincane sengxenye ehlangene ye-weldment (umthungo we-weld) ngesikhathi sokushisela sizoshintsha ngesikhathi senqubo yokwakheka, singakha isixhumanisi esibuthakathaka esakhiweni esishisiwe. Ubulukhuni bokushisela bungabonisa ngqo ukuthi inqubo yokushisela inengqondo yini. Khona-ke indlela yokuhlola ubulukhuni be-Vickers iyindlela esiza ukuhlola ikhwalithi yama-weld. Umhloli wobulukhuni be-Vickers we-Laizhou Laihua Hardness Tester Factory angenza ukuhlolwa kobulukhuni ezingxenyeni ezishisiwe noma ezindaweni zokushisela. Uma usebenzisa umhloli wobulukhuni be-Vickers ukuhlola izingxenye ezishisiwe, kufanele kuqashelwe izimo zokuhlola ezilandelayo:
Ukuthamba kwesampula: Ngaphambi kokuhlola, sigaya i-weld ezohlolwa ukuze senze ubuso bayo bube bushelelezi, bungenawo ungqimba lwe-oxide, imifantu nezinye izinkinga.
Emugqeni ophakathi nendawo yokushisela, thatha iphuzu endaweni egobile njalo nge-100 mm ukuze uvivinye.
Ukukhetha amandla okuhlola ahlukene kuzoholela emiphumeleni ehlukene, ngakho-ke kumelwe sikhethe amandla okuhlola afanele ngaphambi kokuhlola.
2. Ungayisebenzisa kanjani i-Vickers hardness tester (i-micro Vickers hardness tester) ukuthola ukujula kwesendlalelo esiqinile?
Ungakubona kanjani ukujula kwengqimba eqinile yezingxenye zensimbi ngokwelashwa kwendawo efana ne-carburizing, i-nitriding, i-decarburization, i-carbonitriding, njll., kanye nezingxenye zensimbi ezicinyiwe?
Ukujula kwesendlalelo esiqinisiwe okusebenzayo kusetshenziselwa kakhulu ukushisa indawo ukuze kubangele izinguquko zesakhiwo kanye nokusebenza ebusweni bensimbi ukuze kufezwe umphumela wokwanda kobulukhuni namandla kanye nokuqina. Kubhekisela ekulinganisweni kusukela ohlangothini oluqondile lobuso bengxenye kuya emngceleni wesakhiwo esincane esibekiwe. Noma ibanga lesendlalelo esiqinisiwe lobunzima obuncane obubekiwe. Ngokuvamile sisebenzisa indlela yokuqina kwe-gradient yesihloli sokuqina kwe-Vickers ukuthola ukujula kwesendlalelo esiqinisiwe okusebenzayo kwento yokusebenza. Umgomo ukuthola ukujula kwesendlalelo esiqinisiwe okusebenzayo ngokusekelwe ekushintsheni kobulukhuni be-micro-Vickers kusukela ebusweni kuya enkabeni yengxenye.
Ukuze uthole izindlela ezithile zokusebenza, sicela ubheke ividiyo yokusebenza kwe-Vickers hardness tester yenkampani yethu. Okulandelayo isingeniso esilula sokusebenza:
Lungisa isampula njengoba kudingeka, bese indawo yokuhlola kufanele ipholishwe ibe yindawo yesibuko.
Khetha amandla okuhlola esihloli sokuqina kwe-Vickers. I-gradient yokuqina ilinganiswa ezindaweni ezimbili noma ngaphezulu. Ukuqina kwe-Vickers kulinganiswa emgqeni owodwa noma ngaphezulu ohambisanayo oqonde phezulu.
Ukudweba ijika lobunzima ngokusekelwe kudatha elinganisiwe, kungaziwa ukuthi ibanga eliqondile ukusuka ebusweni bengxenye kuya ku-550HV (ngokuvamile) ukujula kwengqimba eqinile okusebenzayo.
3. Ungayisebenzisa kanjani i-Vickers hardness tester ekuhlolweni kokuqina kokuphuka (indlela yokuhlola ukuqina kokuphuka kwe-Vickers)?
Ukuqina kokuqhekeka yinani lokumelana eliboniswa yizinto lapho isampula noma ingxenye iqhekeka ngaphansi kwezimo ezingazinzile njengokuqhekeka noma amaphutha afana nokuqhekeka.
Ukuqina kokuqhekeka kumelela ikhono lento yokuvimbela ukusabalala kwemifantu futhi kuyinkomba yobuningi bokuqina kwezinto.
Uma wenza isivivinyo sokuqina kokuqhekeka, qala ngokupholisha ubuso besampula yesivivinyo bube sendaweni yesibuko. Ku-Vickers hardness tester, sebenzisa i-conical diamond indenter ye-Vickers hardness tester ukuze wenze i-indenti endaweni epholishiwe enomthwalo ongu-10Kg. Imifantu elungisiwe kusengaphambili ikhiqizwa kuma-vertices amane ophawu. Ngokuvamile sisebenzisa i-Vickers hardness tester ukuthola idatha yokuqina kokuqhekeka.
