1. Sebenzisa indlela ye-Vickers hardness tester yezingxenye ezishiselwe (ukuhlola ubulukhuni be-Weld Vickers):
Njengoba i-microstructure yengxenye ehlangene ye-weldment (i-weld seam) ngesikhathi se-welding izoshintsha ngesikhathi senqubo yokubunjwa, ingase yakhe isixhumanisi esibuthakathaka esakhiweni esihlanganisiwe.Ukuqina kwe-welding kungabonisa ngokuqondile ukuthi inqubo yokushisela inengqondo yini.Bese ubulukhuni be-Vickers Indlela yokuhlola iyindlela esiza ukuhlola izinga lokushisela.Umhloli wokuqina we-Vickers wase-Laizhou Laihua Hardness Tester Factory angakwazi ukuhlola ubulukhuni ezingxenyeni ezishiselwe noma ezindaweni zokushisela.Uma usebenzisa isihloli sokuqina sokuqina kwe-Vickers ukuhlola izingxenye ezishiselwe, kufanele kuqashelwe izimo zokuhlola ezilandelayo:
Ukucaba kwesampula: Ngaphambi kokuhlola, sigaya i-weld ukuze ihlolwe ukwenza indawo yayo ibushelelezi, ingabi nangqimba ye-oxide, imifantu nokunye ukukhubazeka.
Emgqeni ophakathi nendawo we-weld, thatha iphuzu endaweni egobile njalo ngo-100 mm ukuze uhlolwe.
Ukukhetha amandla okuhlola ahlukene kuzoholela emiphumeleni ehlukene, ngakho kufanele sikhethe amandla okuhlola afanele ngaphambi kokuhlola.
2. Isetshenziswa kanjani i-Vickers hardness tester (i-micro Vickers hardness tester) ukuze kutholwe ukujula kongqimba oluqinile?
Ungakubona kanjani ukujula kongqimba oluqinile lwezingxenye zensimbi ngokwelashwa okungaphezulu okufana ne-carburizing, i-nitriding, i-decarburization, i-carbonitriding, njll., nezingxenye zensimbi eziye zacinywa?
Ukujula kwesendlalelo esiqinile okusebenzayo kusetshenziselwa kakhulu ukushisa endaweni ukuze kubangele izinguquko zesakhiwo nokusebenza endaweni yensimbi ukuze kuzuzwe umphumela wokukhulisa ubulukhuni namandla nokuqina.Isho ukulinganisa ukusuka ekuqondeni okuqondile kwendawo engaphezulu kuya emngceleni wesakhiwo esincane esicacisiwe.Noma ibanga lesendlalelo esiqinile sokuqina okuncane okucacisiwe.Ngokuvamile sisebenzisa indlela yobulukhuni begradient yesihloli sokuqina sokuqina kwe-Vickers ukuze sithole ukujula kwesendlalelo esiqinile esisebenzayo socezu lokusebenza.Umgomo uwukuthola ukujula kongqimba oluqinile olusebenzayo ngokusekelwe ekushintsheni kokuqina kwe-micro-Vickers kusuka phezulu kuya maphakathi nengxenye.
Ukuze uthole izindlela ezithile zokusebenza, sicela ubheke ividiyo yenkampani yethu yomhloli wokuqina we-Vickers.Okulandelayo isingeniso esilula sokusebenza:
Lungiselela isampula njengoba kudingeka, futhi indawo yokuhlola kufanele ipholishwe endaweni yesibuko.
Khetha amandla okuhlola okuhlola ubulukhuni be-Vickers.Igradient yokuqina ikalwa ezindaweni ezimbili noma ngaphezulu.Ukuqina kwe-Vickers kukalwa emugqeni owodwa noma ngaphezulu ohambisanayo obheke phezulu.
Ukudweba ijika lokuqina ngokusekelwe kudatha elinganisiwe, kungaziwa ukuthi ibanga eliqondile ukusuka ebusweni bengxenye ukuya ku-550HV (ngokuvamile) ukujula kongqimba oluqinile olusebenzayo.
3. Isetshenziswa kanjani i-Vickers tester yokuqina kokuqina kokuqina kokuphuka (indlela yokuhlola ubulukhuni be-Vickers)?
Ukuqina kokuqhekeka yivelu yokumelana eboniswa okokusebenza lapho isifanekiso noma ingxenye iphuka ngaphansi kwezimo ezingazinzile njengokuqhekeka noma ukonakala okufana nokuqhekeka.
Ukuqina kokuphuka kumelela ikhono lempahla ukuvimbela ukusakazeka kokuqhekeka futhi kuyinkomba yobuningi bokuqina kwento.
Uma wenza ukuhlolwa kokuqina kokuphuka, qala ngokupholisha ingaphezulu lesampula lokuhlola endaweni yesibuko.Esihlolini sokuqina sokuqina kwe-Vickers, sebenzisa i-indenter yedayimane eyindilinga yesihloli sokuqina sokuqina kwe-Vickers ukuze wenze i-indent endaweni epholishiwe enomthwalo ongu-10Kg.Imifantu eyenziwe ngaphambilini ikhiqizwa kuma-vertices amane ophawu.Ngokuvamile sisebenzisa i-Vickers tester hardness ukuze sithole idatha yokuqina kokuphuka.
