Ubulukhuni bukaVickers buyindlela ejwayelekile yokuveza ubulukhuni bezinto eziphakanyiswe yiBritish Robert L. Smith noGeorge E. Sandland ngo-1921 kwaVickers Ltd. Lena enye indlela yokuhlola ubulukhuni elandela izindlela zokuhlola ubulukhuni bukaRockwell noBrinell.
1 Isimiso sokuhlola ubulukhuni be-Vickers:
Isihloli sokuqina kwe-Vickers sisebenzisa umthwalo ongu-49.03 ~ 980.7N ukucindezela i-intruder yedayimane enesikwele esine-engeli engu-136° ebusweni bezinto ezibonakalayo. Ngemva kokuyigcina isikhathi esithile, kala i-indent ngokuvundlile. Ubude bomugqa, bese ubala inani lokuqina kwe-Vickers ngokwefomula.
2. Ububanzi besicelo sokulayisha:
01: Isihloli sokuqina kwe-Vickers esinomthwalo ongu-49.03 ~ 980.7N sifanelekela ukulinganisa ubulukhuni bezinto zokusebenza ezinkulu kanye nezendlalelo ezijulile;
02: Ubunzima be-Vickers yomthwalo omncane, umthwalo wokuhlola <1.949.03N, ofanele ukulinganisa ubulukhuni bezinto zokusebenza ezincane, izindawo zamathuluzi noma izembozo;
03: Ubulukhuni be-Micro-Vickers, umthwalo wokuhlola <1.961N, kufanelekile ekulinganisweni kobulukhuni be-foil yensimbi kanye nezendlalelo zobuso ezincane kakhulu.
Ngaphezu kwalokho, ifakwe i-Knoop indenter, ingalinganisa ubulukhuni be-Knoop bezinto ezibuthakathaka neziqinile njengengilazi, izinto zobumba, i-agate, namatshe ayigugu okwenziwa.
Izinzuzo ezi-3 zomhloli wokuqina kwe-Vickers:
1) Ububanzi bokulinganisa bubanzi, kusukela ezinsimbini ezithambile kuya kubahloli bokuqina kakhulu kuya ezinsimbini eziqinile kakhulu, kanti ububanzi bokulinganisa busukela emananini obuqinile be-Vickers ambalwa kuya kwayizinkulungwane ezintathu.
2) Ukugoba kuncane futhi akulimazi umsebenzi. Kungasetshenziswa ekuhlolweni kobulukhuni bezinto zokusebenza ezingaphezulu kwazo okungenakulimala.
3) Ngenxa yamandla ayo amancane okuhlola, amandla amancane okuhlola angafinyelela ku-10g, ngakho-ke ingathola ezinye izinto zokusebenza ezincane nezincane.
4 Izimo ezimbi zomhloli wobulukhuni be-Vickers: Uma kuqhathaniswa nezindlela zokuhlola ubulukhuni be-Brinell ne-Rockwell, ukuhlolwa kobulukhuni be-Vickers kunezidingo zokushelela kwendawo yokusebenza, kanti ezinye izinto zokusebenza zidinga ukupholishwa, okuthatha isikhathi futhi kudinga umsebenzi omningi; ukulungiswa Umhloli wobulukhuni unembile futhi awufanele ukusetshenziswa ezindaweni zokusebenzela noma endaweni. Usetshenziswa kakhulu ezindaweni zokucwaninga.
Uchungechunge lwe-Vickers hardness tester olu-5
1) Isihloli sokuqina kwe-Vickers esingabizi
2) Isivivinyo sokuqina kwesikrini sokuthinta sedijithali i-Vickers
3) Isihloli sokuqina kwe-Vickers esizenzakalelayo ngokuphelele
Isikhathi sokuthunyelwe: Disemba 15-2023
