Vickers hardness ke tekanyetso ea ho hlalosa ho thatafala ha thepa e hlahisitsoeng ke British Robert L. Smith le George E. Sandland ka 1921 ho Vickers Ltd. Ena ke mokhoa o mong oa ho hlahloba boima bo latelang mekhoa ea ho hlahloba thata ea Rockwell le Brinell.
1 Molao-motheo oa Vickers hardness tester:
Vickers hardness tester e sebelisa mojaro oa 49.03 ~ 980.7N ho hatella sekoaelo sa taemane se nang le sekoaelo sa daemane se nang le angle e kenyellelitsoeng ea 136 ° holim'a thepa.Ka mor'a ho e boloka ka nako e itseng, lekanya indentation ka diagonally.Bolelele ba mela, ebe u bala boleng ba boima ba Vickers ho latela foromo.
2.Moroalo oa ts'ebeliso ea lisebelisoa:
01: The Vickers hardness tester e nang le mojaro oa 49.03 ~ 980.7N e loketse ho lekanya boima ba li-workpieces tse kholoanyane le likarolo tse tebileng tsa holim'a metsi;
02: boima bo bonyenyane ba Vickers, boima ba teko <1.949.03N, bo loketseng tekanyo ea boima ba li-workpieces tse tšesaane, lisebelisoa tsa lisebelisoa kapa liaparo;
03: boima ba li-Micro-Vickers, boima ba teko <1.961N, bo loketseng tekanyo ea boima ba li-foil tsa tšepe le likarolo tse tšesaane haholo tsa holim'a metsi.
Ho feta moo, e nang le "indenter" ea Knoop, e khona ho lekanya boima ba Knoop ba lisebelisoa tse brittle le tse thata tse kang khalase, ceramics, agate le mahakoe a maiketsetso.
3 Melemo ea Vickers hardness tester:
1) Lethathamo la litekanyo le pharaletse, ho tloha ho litšepe tse bonolo ho isa ho li-ultra-hardness testers ho lirafshoa tse thata haholo, 'me mefuta ea litekanyo e tloha ho tse seng kae ho isa ho tse likete tse tharo tsa boleng ba boima ba Vickers.
2) The indentation e nyenyane 'me ha e senye workpiece.E ka sebelisoa bakeng sa tlhahlobo ea boima ba li-workpieces tseo bokaholimo ba tsona bo ke keng ba senyeha.
3) Ka lebaka la matla a eona a fokolang a teko, matla a fokolang a teko a ka fihla ho 10g, kahoo a ka lemoha lisebelisoa tse nyenyane le tse nyenyane tsa mosebetsi.
4 Mefokolo ea Vickers hardness tester: Ha e bapisoa le mekhoa ea ho hlahloba boima ba Brinell le Rockwell, tlhahlobo ea boima ba Vickers e na le litlhoko tsa ho boreleli ha karolo ea mosebetsi, 'me lisebelisoa tse ling li hloka ho belisoa, tse jang nako le mosebetsi o boima;tlhokomelo The hardness tester e batla e nepahetse 'me ha ea lokela ho sebelisoa lithupelong kapa setšeng.E sebelisoa haholo lilaboratoring.
