Ubukana bwa Vickers ni igipimo ngenderwaho cyo kugaragaza ubukana bw'ibikoresho byatanzwe n'Umwongereza Robert L. Smith na George E. Sandland mu 1921 muri Vickers Ltd. Ubu ni ubundi buryo bwo gupima ubukana bukurikiza uburyo bwo gupima ubukana bwa Rockwell na Brinell.
1 Ihame ry'igikoresho cyo gupima ubukana bwa Vickers:
Igipimo cy'ubukana bwa Vickers gikoresha umutwaro wa 49.03 ~ 980.7N kugira ngo gikanda diyama ifite ishusho ya kare ifite inguni ya 136° ku buso bw'ibikoresho. Nyuma yo kuyigumana igihe runaka, pima aho intera iri hagati y'umurongo n'umurongo. Uburebure bw'umurongo, hanyuma ubare agaciro k'ubukana bwa Vickers ukurikije formula.
2. Urutonde rw'ibikoresho byo gushyiramo:
01: Imashini ipima ubukana bwa Vickers ifite umutwaro wa 49.03 ~ 980.7N ikwiriye gupima ubukana bw'ibikoresho binini n'ibice by'ubuso byimbitse;
02: Ubukana bw'umutwaro muto wa Vickers, umutwaro w'igerageza <1.949.03N, ukwiriye gupima ubukana bw'ibikoresho byoroshye, ubuso bw'ibikoresho cyangwa irangi;
03: Ubukana bwa Micro-Vickers, uburemere bw'ikizamini <1.961N, bukwiriye gupima ubukana bwa foil z'icyuma n'ibice by'ubuso bito cyane.
Byongeye kandi, ifite Knoop indenter, ishobora gupima ubukana bwa Knoop bw'ibikoresho byoroshye kandi bikomeye nk'ibirahure, ibumba, agate, n'amabuye y'agaciro y'ubukorano.
Ibyiza 3 by'igikoresho gipima ubukana bwa Vickers:
1) Ingano y'ibipimo ni nini, kuva ku byuma byoroshye kugeza ku bikoresho bipima ubukana bwabyo kugeza ku byuma bikomeye cyane, kandi ingano y'ibipimo iri hagati y'agaciro k'ubukana bwa Vickers n'ibihumbi bitatu.
2) Icyuho ni gito kandi nticyangiza igikoresho. Gishobora gukoreshwa mu gupima ubukana bw'ibikoresho bifite ubuso budashobora kwangirika.
3) Kubera imbaraga nke zo gupima, imbaraga nke zo gupima zishobora kugera kuri 10g, bityo ikabasha kubona uduce duto n'utworoshye two gukora.
4 Ingaruka mbi z'igikoresho gipima ubukana bwa Vickers: Ugereranyije n'uburyo bwa Brinell na Rockwell bwo gupima ubukana bwa Vickers, ikizamini cy'ubukana bwa Vickers gifite ibisabwa kugira ngo ubuso bw'igikoresho burusheho koroha, kandi bimwe mu bikoresho bigomba gusigwa, bifata igihe kinini kandi bisaba imbaraga nyinshi; kubungabunga Iki gipimo cy'ubukana cyarakozwe neza kandi ntikibereye gukoreshwa mu mashami cyangwa aho bakorera. Gikoreshwa cyane muri laboratwari.
Urutonde rwa 5 rw'ibikoresho byo gupima ubukana bwa Vickers
1) Igipimo cy'ubukana bwa Vickers gihendutse
2) Imashini ipima ubukana bwa Vickers ikoresheje ecran ya digitale
3) Igipimo cy'ubukana bwa Vickers cyikora burundu
