Rockwell Knoop da hanyoyin gwajin taurin Vickers don yumbu nitride aluminium da hanyoyin gwaji don birgima na ƙarfe

Hanyar gwajin taurin 1.Rockwell Knoop Vickers don ceramics nitride aluminum
Tunda kayan yumbu suna da tsari mai rikitarwa, suna da wuya kuma suna da rauni a yanayi, kuma suna da ƙananan nakasar filastik, hanyoyin maganganun taurin da aka saba amfani da su sun haɗa da taurin Vickers, taurin Knoop da taurin Rockwell. Kamfanin Shancai yana da nau'ikan gwaje-gwajen tauri iri-iri, tare da gwaje-gwajen taurin daban-daban da masu gwada tauri iri-iri.
Ana iya amfani da ma'auni masu zuwa azaman tunani:
GB/T 230.2 Abubuwan Karfe na Rockwell Hardness Gwajin:
Akwai ma'aunin taurin Rockwell da yawa, kuma kayan yumbu gabaɗaya suna amfani da ma'aunin HRA ko HRC.
GB/T 4340.1-1999 Metal Vickers gwajin tauri da GB/T 18449.1-2001 Metal Knoop gwajin taurin.
Hanyoyin ma'auni na Knoop da Micro-Vickers iri ɗaya ne, bambanci shine nau'in indenters daban-daban da aka yi amfani da su.
Yana da kyau a lura cewa saboda yanayin musamman na samfurin, zamu iya cire indentations na Vickers mara inganci bisa ga yanayin shigarwa yayin aunawa don samun ƙarin cikakkun bayanai.
2.Testing hanyoyin don karfe mirgina bearings
Dangane da hanyoyin gwajin taurin ƙarfe da sassa masu ɗaukar ƙarfe mara ƙarfe da aka kayyade a cikin JB/T7361-2007, akwai hanyoyin gwaji da yawa bisa ga tsarin aikin aiki, waɗanda duk ana iya gwada su tare da gwajin taurin Shancai:
1) Hanyar gwajin taurin Vickers
Gabaɗaya, ana gwada sassa masu taurin kai ta hanyar gwajin taurin Vickers. Ya kamata a biya hankali ga ƙarewar saman aikin da zaɓin ƙarfin gwajin.
2) Hanyar gwajin taurin Rockwell
Yawancin gwaje-gwajen taurin Rockwell ana yin su ta amfani da sikelin HRC. Shancai Rockwell taurin gwargwado ya tara shekaru 15 gwaninta kuma zai iya m biyan duk bukatun.
3) Hanyar gwajin taurin Leeb
Ana iya amfani da gwajin taurin Leeb don bearings ɗin da aka girka ko da wuya a haɗa su. Daidaiton ma'aunin sa bai kai na ma'aunin taurin benchtop ba.
Wannan ma'auni ya fi dacewa da gwajin taurin sassa na ƙarfe, ɓoyayyiya da sassa masu ɗauri da gamammen sassa da kuma sassan da ba na ƙarfe ba.
