Gukomera kwa Vickers ni igipimo cyo kwerekana ubukana bwibikoresho byasabwe n’umwongereza Robert L. Smith na George E. Sandland mu 1921 muri Vickers Ltd. Ubu ni ubundi buryo bwo gupima ubukana bukurikira ubukana bwa Rockwell hamwe nuburyo bwo gupima ubukana bwa Brinell.
1 Ihame rya Vickers igerageza gukomera:
Igeragezwa rya Vickers rikoresha umutwaro wa 49.03 ~ 980.7N kugirango ukande umurambararo wa diyama winjiye ufite impande enye zingana na 136 ° hejuru yibintu.Nyuma yo kuyibungabunga mugihe cyagenwe, bapima indentation cyane.Uburebure bwumurongo, hanyuma ubare Vickers gukomera agaciro ukurikije formula.
2.Umurongo wo gusaba:
01: Ikigeragezo gikomeye cya Vickers gifite umutwaro wa 49.03 ~ 980.7N gikwiranye no gupima ubukana bwibikorwa binini hamwe nubutaka bwimbitse;
02.
03: Micro-Vickers gukomera, umutwaro wikizamini <1.961N, ukwiranye no gupima ubukana bwa fayili yicyuma hamwe nubutaka bworoshye cyane.
Mubyongeyeho, ifite ibikoresho bya Knoop indenter, irashobora gupima ubukana bwa Knoop bwibikoresho byoroshye kandi bikomeye nk'ikirahure, ububumbyi, agate, n'amabuye y'agaciro.
3 Ibyiza bya Vickers igerageza:
1) Ibipimo byo gupima ni binini, uhereye ku byuma byoroheje kugeza ku bizamini bya ultra-hardness kugeza ku byuma bikomeye cyane, kandi ibipimo bipima kuva ku bihumbi bike kugeza ku bihumbi bitatu Vickers.
2) Indentation ni nto kandi ntabwo yangiza igihangano.Irashobora gukoreshwa mugupima ubukana bwibikorwa bidafite ubuso budashobora kwangirika.
3) Kubera imbaraga zayo zo kwipimisha, imbaraga ntarengwa zo kugerageza zishobora kugera kuri 10g, bityo irashobora gutahura uduce duto duto kandi duto.
4 Ingaruka zo gupima ubukana bwa Vickers: Ugereranije nuburyo bwo gupima ubukana bwa Brinell na Rockwell, ikizamini gikomeye cya Vickers gifite ibisabwa kugirango uburinganire bwakazi bukorwe, kandi ibihangano bimwe na bimwe bigomba gukosorwa, bikaba bitwara igihe kandi bitwara akazi;kubungabunga Ikizamini cyo gukomera kirasobanutse neza kandi ntigikwiriye gukoreshwa mumahugurwa cyangwa kurubuga.Ikoreshwa cyane muri laboratoire.
5 Vickers gukomera kwipimisha urukurikirane
1) Ubukungu Vickers igerageza gukomera
2) Kugaragaza ibyuma bya digitale ya ecran ya Vickers igerageza
3) Byuzuye byikora Vickers igerageza
