1. Yi amfani da Vickers hardness tester na welded sassa (Weld Vickers hardness test) hanya:
Tun da microstructure na ɓangaren haɗin gwiwa na walƙiya (weld seam) a lokacin waldi zai canza a lokacin tsarin samuwar, yana iya haifar da haɗin gwiwa mai rauni a cikin tsarin welded.Taurin walda zai iya nuna kai tsaye ko tsarin walda yana da ma'ana.Sannan taurin Vickers Hanyar dubawa hanya ce da ke taimakawa tantance ingancin walda.Vickers hardness tester na Laizhou Laihua Hardness Tester Factory na iya yin gwajin taurin akan sassa na walda ko wuraren walda.Lokacin amfani da ma'aunin taurin Vickers don gwada sassan walda, ya kamata a lura da yanayin gwajin masu zuwa:
Lalacewar samfurin: Kafin gwaji, muna niƙa weld ɗin da za a gwada don sanya saman sa santsi, babu oxide Layer, fasa da sauran lahani.
A kan tsakiyar layin walda, ɗauki batu a kan mai lanƙwasa kowane 100 mm don gwaji.
Zaɓin rundunonin gwaji daban-daban zai haifar da sakamako daban-daban, don haka dole ne mu zaɓi ƙarfin gwajin da ya dace kafin gwaji.
2. Yadda za a yi amfani da Vickers hardness tester (micro Vickers hardness tester) don gano zurfin taurin Layer?
Yadda za a gano zurfin daɗaɗɗen sassa na ƙarfe tare da jiyya na sama kamar carburizing, nitriding, decarburization, carbonitriding, da dai sauransu, da sassan karfe waɗanda aka kashe?
Ana amfani da zurfin zurfin zurfin daɗaɗɗen mai inganci don zafi a cikin gida don haifar da canje-canjen tsari da aiki akan saman ƙarfe don cimma tasirin ƙara ƙarfi da ƙarfi da ƙarfi.Yana nufin ma'auni daga madaidaiciyar shugabanci na ɓangaren ɓangaren zuwa ƙayyadadden ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun tsarin microstructure.Ko nisan Layer na ƙayyadadden microhardness.Yawancin lokaci muna amfani da hanyar taurin gradient na mai gwada taurin Vickers don gano ingantaccen zurfin Layer na kayan aiki.Ka'idar ita ce gano zurfin zurfin Layer mai tasiri mai ƙarfi dangane da canji a cikin taurin micro-Vickers daga saman zuwa tsakiyar ɓangaren.
Don takamaiman hanyoyin aiki, da fatan za a koma zuwa kamfaninmu na Vickers hardness tester video aiki.Mai zuwa shine gabatarwar aiki mai sauƙi:
Shirya samfurin kamar yadda ake buƙata, kuma gwajin gwajin ya kamata a goge shi zuwa saman madubi.
Zaɓi ƙarfin gwaji na mai gwajin taurin Vickers.Ana auna gradient taurin a wurare biyu ko fiye.Ana auna taurin Vickers akan layi ɗaya ko fiye daidai da saman.
Zana madaidaicin taurin dangane da bayanan da aka auna, ana iya sanin cewa nisa a tsaye daga saman ɓangaren zuwa 550HV (gaba ɗaya) shine ingantaccen zurfin Layer.
3. Yadda ake amfani da Vickers hardness tester don gwajin taurin karaya (hanyar gwajin karye taurin Vickers)?
Karya taurin shine ƙimar juriya da kayan ke nunawa lokacin da samfurin ko bangaren ya karye ƙarƙashin yanayi mara ƙarfi kamar tsaga ko lahani mai kama.
Karya taurin yana wakiltar ƙarfin abu don hana yaɗuwar fashe kuma alama ce mai ƙididdigewa na taurin abu.
Lokacin yin gwajin taurin karaya, fara goge saman samfurin gwajin zuwa saman madubi.A kan ma'aunin taurin Vickers, yi amfani da maƙallan lu'u-lu'u na conical na na'urar gwajin taurin Vickers don yin nuni a saman da aka goge tare da nauyin 10Kg.Ana haifar da tsagewar da aka riga aka keɓance a kusurwa huɗu na alamar.Gabaɗaya muna amfani da mai gwajin taurin Vickers don samun bayanan taurin karaya.
