Origon of Vickers hardness tester
Vickers hardness o se faʻataʻitaʻiga mo le faʻatusaina o mea maʻaʻa na fuafuaina e Robert L. Smith ma George E. Sandland i le 1921 i Vickers Ltd. O le isi lea metotia suʻega maaa e mulimuli i le Rockwell maaa ma Brinell metotia suʻega.
Fa'avae ole Vickers hardness tester:
E faʻaaogaina e le Vickers hardness tester se uta o le 49.03 ~ 980.7N e faʻapipiʻi ai se taimane conical sikuea ma se tulimanu faʻatatau o le 136 ° i luga o le mea.A maeʻa ona taofi mo le taimi faʻapitoa, o le Vickers hardness value e faʻatatau i le fuaina o le umi o le diagonal o le indentation ma le faʻaogaina o le fua.
Ole fa'aogaina ole uta o ituaiga e tolu o Vickers (micro Vickers):
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.
Uta maualalo Vickers faigata, faʻataʻitaʻiga faʻataʻitaʻiga<1.949.03N, talafeagai mo le fuaina o le maaa o mea faigaluega manifinifi, luga o meafaigaluega, poʻo faʻaofuofu;
Micro Vickers ma'a'a, uta su'ega<1.961N, talafeagai mo le fuaina maaa o pepa u'amea 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.
Tulaga lelei ole Vickers hardness tester:
1. E lautele le fuaina, mai masini komepiuta i metals superhard, ma e mafai ona iloa, e amata mai i ni nai i le tolu afe Vickers tulaga faigata.
2. O le faʻailoga e laʻititi ma e le faʻaleagaina ai le mea faigaluega, lea e mafai ona faʻaaogaina mo suʻega faigata i luga o mea faigaluega e le mafai ona faʻaleagaina i luga o le mea faigaluega.
3. Ona o le laʻititi laʻititi o le suʻega, e mafai ona oʻo atu i le 10g le malosi o le suʻega, lea e mafai ona iloa ai ni mea manifinifi ma laiti.
Le lelei ole Vickers hardness tester:
Pe a faatusatusa i le Brinell ma Rockwell metotia suʻega maaa, o le Vickers faigata suʻega e iai manaʻoga mo le lamolemole luga ole mea faigaluega.O nisi mea faigaluega e manaʻomia le faʻamalo, lea e alu ai le taimi ma galue malosi
Vickers malosi su'ega e fai si sa'o ma e le talafeagai mo le fa'aoga i totonu o faleaoga po'o luga ole nofoaga, ma e tele lava ina fa'aoga i fale su'esu'e.
Shandong Shancai Vickers ma'a'a su'ega fa'asologa (ata mo Wang Songxin)
1. Economic Vickers faigata su'ega
2. Fa'aaliga numera ma mata pa'i Vickers maaa su'ega
3. Otometi atoatoa Vickers maaa su'ega
