Vickers hardness o se faʻataʻitaʻiga mo le faʻaalia o le maaa o mea na faʻatulagaina e le British Robert L. Smith ma George E. Sandland i le 1921 i Vickers Ltd. O le isi lea o suʻega faʻataʻitaʻiga e mulimuli i le Rockwell hardness ma Brinell hardness testing method.
1 Fa'avae ole Vickers maaa su'ega:
O le Vickers maaa suʻega faʻaaogaina se uta o le 49.03 ~ 980.7N e faʻapipiʻi ai se faʻailoga taimane faʻailoga sikuea faʻatasi ma le faʻaogaina o le 136 ° i luga o le meafaitino.A mae'a ona fa'atumauina mo se taimi fa'apitoa, fua le fa'ailoga fa'ata'oto.Ole umi ole laina, ona fuafua lea ole tau ole maaa Vickers e tusa ai ma le fua.
2. Load vaega talosaga:
01: O le Vickers hardness tester ma le uta o le 49.03 ~ 980.7N e talafeagai mo le fuaina o le maaa o mea faigaluega tetele ma le loloto o luga o luga;
02: Laiti uta Vickers faigata, faʻataʻitaʻiga faʻataʻitaʻiga <1.949.03N, talafeagai mo le fuaina o le maaa o mea faigaluega manifinifi, luga o meafaigaluega poʻo ufiufi;
03: Micro-Vickers maʻaʻa, uta suʻega <1.961N, talafeagai mo le fuaina o le maaa o pepa uʻamea ma pito sili ona manifinifi.
E le gata i lea, faʻapipiʻiina i le Knoop indenter, e mafai ona fuaina le Knoop maʻaʻa o mea vaivai ma mea faigata e pei o tioata, ceramics, agate, ma maʻa taua.
3 Fa'amanuiaga ole Vickers hardness tester:
1) E lautele le fua, e amata mai i uʻamea vaivai i suʻega ultra-malosi i uʻamea sili-malosi, ma o le fua faʻatatau e amata mai i ni nai i le tolu afe Vickers faʻamaua taua.
2) E laʻititi le faʻailoga ma e le faʻaleagaina ai le mea faigaluega.E mafai ona fa'aoga mo su'ega ma'a'a o mea faigaluega e le mafai ona fa'aleagaina o latou luga.
3) Ona o le laʻititi laʻititi o le suʻega, e mafai ona oʻo atu i le 10g le malosi o le suʻega, ina ia mafai ai ona iloa ni mea manifinifi ma laiti.
4 Le lelei o le Vickers maaa suʻega: Faʻatusatusa i Brinell ma Rockwell metotia suʻega, o le Vickers faigata suʻega e iai manaʻoga mo le lamolemole o le mea faigaluega, ma o nisi mea faigaluega e manaʻomia ona faʻalelei, lea e alu ai le taimi ma galue malosi;tausiga O le su'ega ma'a'a e fai si sa'o ma e le talafeagai mo le fa'aoga i faleaoga po'o luga ole nofoaga.E masani ona faʻaaogaina i fale suʻesuʻe.
5 Vickers ma'a'a su'ega fa'asologa
1) Fa'atauga Vickers faigata su'ega
2) Fa'amatalaga fa'atekinolosi mata pa'i Vickers ma'a'a su'ega
3) Otometi atoatoa Vickers faigata su'ega
