Tšimoloho ea Vickers hardness tester
Vickers hardness ke tekanyetso ea ho emela boima ba lintho tse bonahalang bo sisintsoeng ke Robert L. Smith le George E. Sandland ka 1921 ho Vickers Ltd. Ena ke mokhoa o mong oa ho hlahloba boima ba 'mele o latelang mekhoa ea ho hlahloba boima ba Rockwell le Brinell.
Molao-motheo oa Vickers hardness tester:
The Vickers hardness tester e sebelisa mojaro oa 49.03 ~ 980.7N ho hatella daemane e sekoahelo e nang le sekhahla sa 136 ° ka holim'a thepa.Ka mor'a ho e tšoara ka nako e behiloeng, boleng ba boima ba Vickers bo baloa ka ho lekanya bolelele ba diagonal ba indentation le ho sebelisa foromo.
Lenane la ts'ebeliso ea mojaro ea mefuta e meraro e latelang ea Vickers (micro Vickers):
The Vickers hardness tester e nang le mojaro oa 49.03 ~ 980.7N e loketse tekanyo ea boima ba lisebelisoa tse kholoanyane le likarolo tse tebileng tsa bokaholimo.
Boima bo tlaase ba Vickers, boima ba teko <1.949.03N, bo loketseng tekanyo ea boima ba li-workpieces tse tšesaane, lisebelisoa tsa lisebelisoa, kapa liaparo;
Boima ba Micro Vickers, boima ba teko <1.961N, bo loketseng tekanyo ea boima ba 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.
Melemo ea Vickers hardness tester:
1. Lethathamo la litekanyo le pharaletseng, ho tloha ho lisebelisoa tsa software ho ea ho lirafshoa tse matla haholo, 'me li ka fumanoa, ho tloha ho tse seng kae ho ea ho tse likete tse tharo tsa litekanyetso tsa boima ba Vickers.
2. Indentation e nyenyane 'me ha e senye workpiece, e ka sebelisetsoang tlhahlobo ea boima holim'a li-workpieces tse ke keng tsa senyeha holim'a sebaka sa mosebetsi.
3. Ka lebaka la matla a eona a manyenyane a ho etsa liteko, matla a fokolang a ho hlahloba a ka fihla ho 10g, a khonang ho lemoha lisebelisoa tse nyenyane le tse nyenyane tsa mosebetsi.
Mathata a Vickers hardness tester:
Ha ho bapisoa le mekhoa ea tlhahlobo ea ho thatafala ha Brinell le Rockwell, tlhahlobo ea boima ba Vickers e na le litlhoko tsa boreleli ba bokaholimo ba mosebetsi.Lisebelisoa tse ling li hloka ho belisoa, e leng nako e jang le e hlokang mosebetsi o boima
Litlhahlobo tsa hardness tsa Vickers li batla li nepahetse 'me ha lia lokela ho sebelisoa lithupelong kapa setšeng,' me li sebelisoa haholo lilaboratoring.
Shandong Shancai Vickers letoto la liteko tsa hardness (setšoantšo sa Wang Songxin)
1. Economic Vickers hardness tester
2. Pontšo ea digital le skrine ea ho ama Vickers hardness tester
3. Ka ho feletseng jarolla ka ho iketsa Vickers boima teko
