Gwaje-gwaje da yawa na yau da kullun na gwajin taurin Vickers

 

1. Yi amfani da hanyar gwajin taurin Vickers na sassan da aka haɗa (gwajin taurin Weld Vickers):

Tunda tsarin haɗin gwiwa na walda (dinkin walda) yayin walda zai canza yayin tsarin samarwa, yana iya samar da rauni a cikin tsarin walda. Taurin walda na iya nuna kai tsaye ko tsarin walda ya dace. Sannan taurin Vickers Hanyar dubawa hanya ce da ke taimakawa wajen tantance ingancin walda. Mai gwajin taurin Vickers na Laizhou Laihua Masana'antar Gwajin Taurin Vickers na iya yin gwajin taurin a kan sassan walda ko wuraren walda. Lokacin amfani da mai gwajin taurin Vickers don gwada sassan walda, ya kamata a lura da waɗannan sharuɗɗan gwaji:

Daidaiton samfurin: Kafin a gwada, muna niƙa walda don a gwada ta don ta yi laushi, ba tare da wani lahani na oxide ba, tsagewa da sauran lahani.

A tsakiyar layin walda, ɗauki maki ɗaya a kan saman lanƙwasa kowane 100 mm don gwaji.

Zaɓar ƙarfin gwaji daban-daban zai haifar da sakamako daban-daban, don haka dole ne mu zaɓi ƙarfin gwaji da ya dace kafin a yi gwaji.

2. Yadda ake amfani da na'urar gwajin taurin Vickers (micro Vickers taurin gwajin) don gano zurfin taurin Layer?

Ta yaya za a gano zurfin Layer mai tauri na sassan ƙarfe ta hanyar amfani da maganin saman kamar su carburizing, nitriding, decarburization, carbonitriding, da sauransu, da sassan ƙarfe waɗanda aka kashe su?

Zurfin Layer mai tauri mai tasiri galibi ana amfani da shi don dumama saman a gida don haifar da canje-canje a cikin tsari da aiki a saman ƙarfe don cimma tasirin ƙara tauri da ƙarfi da tauri. Yana nufin aunawa daga tsaye na saman ɓangaren zuwa iyakar tsarin da aka ƙayyade. Ko kuma nisan Layer mai tauri na takamaiman microhardness. Yawanci muna amfani da hanyar tauri mai sauƙi na Vickers don gano zurfin Layer mai tauri mai tasiri na aikin. Ka'idar ita ce gano zurfin Layer mai tauri mai tasiri bisa ga canjin tauri na micro-Vickers daga saman zuwa tsakiyar ɓangaren.

Don takamaiman hanyoyin aiki, da fatan za a duba bidiyon aikin gwajin taurin Vickers na kamfaninmu. Ga gabatarwar aiki mai sauƙi:

Shirya samfurin kamar yadda ake buƙata, kuma ya kamata a goge saman gwajin zuwa saman madubi.

Zaɓi ƙarfin gwajin na'urar gwajin taurin Vickers. Ana auna matakin taurin a wurare biyu ko fiye. Ana auna taurin Vickers akan layi ɗaya ko fiye a layi ɗaya a tsaye a saman.

Zana lanƙwasa mai tauri bisa ga bayanan da aka auna, za a iya sanin cewa nisan tsaye daga saman ɓangaren zuwa 550HV (gabaɗaya) shine zurfin Layer mai tauri mai tasiri.

3. Yadda ake amfani da na'urar gwajin taurin Vickers don gwajin taurin karyewa (hanyar gwajin taurin karyewa ta Vickers)?

Taurin karyewa shine ƙimar juriya da kayan ke nunawa lokacin da samfurin ko ɓangaren ya karye a ƙarƙashin yanayi mara tabbas kamar tsagewa ko lahani kamar tsagewa.

Taurin karyewa yana wakiltar ikon abu na hana yaɗuwar tsagewa kuma alama ce ta adadi na taurin abu.

Lokacin yin gwajin taurin karyewa, da farko a goge saman samfurin gwajin zuwa saman madubi. A kan na'urar gwajin taurin Vickers, yi amfani da ma'aunin lu'u-lu'u mai siffar conical na na'urar gwajin taurin Vickers don yin matsi a saman da aka goge tare da nauyin 10Kg. Ana samar da tsage-tsage da aka riga aka ƙera a wurare huɗu na alamar. Gabaɗaya muna amfani da na'urar gwajin taurin Vickers don samun bayanai game da taurin karyewa.
