Asalin gwajin taurin Vickers
Vickers hardness shine ma'auni don wakiltar taurin kayan da Robert L. Smith da George E. Sandland suka gabatar a 1921 a Vickers Ltd. Wannan wata hanya ce ta gwajin taurin ta bin hanyoyin gwajin taurin Rockwell da Brinell.
Ka'idar gwajin taurin Vickers:
Mai gwada taurin Vickers yana amfani da nauyin 49.03 ~ 980.7N don danna lu'u lu'u-lu'u mai murabba'i tare da kusurwar dangi na 136 ° a cikin saman kayan.Bayan riƙe shi don ƙayyadadden lokacin, ana ƙididdige ƙimar taurin Vickers ta hanyar auna tsayin diagonal na indentation da amfani da dabara.
Kewayon aikace-aikacen lodi na nau'ikan Vickers guda uku masu zuwa (micro Vickers):
Mai gwada taurin Vickers tare da nauyin 49.03 ~ 980.7N ya dace don auna ma'auni na manyan kayan aiki da yadudduka masu zurfi.
Low load Vickers taurin, gwajin gwaji <1.949.03N, dace da taurin ma'auni na bakin ciki workpieces, kayan aiki saman, ko coatings;
Micro Vickers taurin, gwajin gwaji <1.961N, dace da ma'aunin taurin foils na ƙarfe da yadudduka na bakin ciki sosai.
Bugu da kari, sanye take da indenter na Knoop, zai iya auna taurin Knoop na gagajewa da kayan aiki masu wuya kamar gilashi, yumbu, agate, da duwatsu masu daraja.
Amfanin mai gwada taurin Vickers:
1. Ma'aunin ma'auni yana da faɗi, daga karafa na software zuwa karafa masu ƙarfi, kuma ana iya gano shi, daga 'yan kaɗan zuwa ƙimar taurin Vickers dubu uku.
2. Ƙaƙwalwar ƙarami ne kuma baya lalata kayan aiki, wanda za'a iya amfani dashi don gwajin gwagwarmaya akan kayan aikin da ba za a iya lalacewa ba a saman kayan aikin.
3. Saboda ƙananan ƙarfin gwajinsa, mafi ƙarancin ƙarfin gwajin zai iya kaiwa 10g, wanda zai iya gano wasu sirara da ƙananan kayan aiki.
Rashin amfanin Vickers hardness tester:
Idan aka kwatanta da hanyoyin gwajin taurin Brinell da Rockwell, gwajin taurin Vickers yana da buƙatu don santsin saman kayan aikin.Wasu kayan aikin suna buƙatar goge goge, wanda ke ɗaukar lokaci kuma yana ɗaukar aiki
Vickers hardness testers suna da madaidaici kuma ba su dace da amfani da su a wuraren bita ko a wurin ba, kuma galibi ana amfani da su a dakunan gwaje-gwaje.
