Hanyar gwajin taurin Micro Vickers wurin walda

Taurin da ke wurin da ke kewaye da walda zai iya taimakawa wajen tantance karyewar walda, ta haka zai taimaka maka ka tantance ko walda tana da ƙarfin da ake buƙata, don haka hanyar gwajin taurin Vickers hanya ce da ke taimakawa wajen tantance ingancin walda.

Kamfanin Gwajin Taurin Vickers na Shandong Shancai /Laizhou Laihua na Kamfanin Gwajin Kayan Aiki na Vickers zai iya yin gwajin taurin a kan sassan walda ko wuraren walda. Lokacin gwada taurin wurin walda, za a yi ma'aunin maki da yawa a wani nisa daga gefen samfurin ko saman wurin walda. Bayan samun ma'aunin maki da yawa, ana iya auna ƙimar taurin ta hanyar aunawa akai-akai kuma ana iya samun jadawalin lanƙwasa.

Lokacin amfani da na'urar gwajin taurin Vickers don gwada sassan da aka haɗa, ya kamata a lura da waɗannan yanayin gwaji:

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

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

3. 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.

Mai gwajin microhardness yana da buƙatu don kammala saman samfurin da aka gwada, wanda ke buƙatar a shirya shi da kyau bisa ga samfurin ƙarfe.

Ka'idar gwajin taurin kai a cikin hanyar gwajin taurin kai iri ɗaya ce da taurin Vickers, amma nauyin da aka yi amfani da shi ya fi ƙanƙanta fiye da taurin Vickers mai ƙarancin nauyi, yawanci ƙasa da 1000g, kuma sakamakon shiga shine ƙananan microns zuwa ƙananan microns biyu, don haka gwajin taurin kai yana ba da hanya mai sauƙi don nazarin halayen tsarin ƙananan Layer ɗin da za a iya shiga. Ana amfani da shi sosai don tantance taurin kowane mataki a saman da kuma a cikin Layer ɗin da ke shiga.

Alamar taurin micro yawanci ana bayyana ta ta hanyar HV, kuma ƙa'idar tantancewa da hanyarta sun yi kama da hanyar taurin Vickers. Tsarin lodi, tsarin aunawa da daidaiton indent na mai gwajin taurin micro sun fi buƙata fiye da na mai gwajin taurin Vickers mai ƙarancin nauyi. A halin yanzu, ana amfani da mai gwajin taurin micro sosai a cikin ƙananan kayan aiki, kuma saboda girman girman zai iya kaiwa sau 400, sau da yawa ana amfani da shi azaman ƙaramin na'urar hangen nesa ta ƙarfe.

A lokacin amfani, ya kamata a kula da nauyin kaya, micrometer da indent na na'urar gwajin microhardness, wanda ya kamata a duba kafin amfani, kuma ana amfani da toshewar taurin don cikakken gano ƙimar da ke nuna shi.

Mai gwajin ƙarfin lantarki yana amfani da nauyin da ke cikin aikin gwaji kamar yadda ya kamata, ba tare da tasiri ko girgiza ba. Domin tabbatar da daidaiton sakamakon gwajin, yawanci yana da mahimmanci a auna sau da yawa a sassa daban-daban, kuma a nemo matsakaicin ƙimar da za ta wakilci ƙimar ƙarfin matakin gwajin iska ko matakin ƙarfe. Ga matakin shigar iska da ake amfani da shi a babban zafin jiki, ana iya auna taurinsa ta amfani da na'urar gwajin ƙarfin lantarki mai zafi.
