Iko kuoma panzvimbo yakapoteredza weld kunogona kubatsira kuongorora brittleness ye weld, nokudaro zvichikubatsira kuona kana weld ine simba rinodiwa, saka weld Vickers kuoma kwekuedza nzira inzira inobatsira kuongorora kunaka kweweld.
Shandong Shancai / Laizhou Laihua Testing Instrument Company's Vickers hardness tester inogona kuedza kuomarara pazvikamu zvakakanyiwa kana nzvimbo dzekubatira.Paunenge uchiyedza kuomarara kwenzvimbo yewelding, kuyerwa kwe-multi-point kuchaitwa pane imwe chinhambwe kubva kumucheto wesample kana pamusoro peiyo welding point.Mushure mekuwana iyo yakawanda-point indentation, kukosha kwekuoma kunogona kuyerwa nekuyera kunoramba kuripo uye curve graph inogona kuwanikwa.
Paunenge uchishandisa Vickers kuomarara tester kuyedza zvikamu zvakasungwa, zvinotevera bvunzo mamiriro anofanirwa kucherechedzwa:
1. Flatness yemuenzaniso: Tisati taedza, tinokuya weld kuti iongororwe kuti iite kuti nzvimbo yaro igare yakatsetseka, isina oxide layer, kuputika uye zvimwe zvikanganiso.
2. Pamutsetse wepakati we weld, tora poindi pane yakakombama pese 100 mm yekuongorora.
3. Kusarudza masimba ekuedza akasiyana kunoguma nemigumisiro yakasiyana, saka tinofanira kusarudza simba rekuedza rakakodzera tisati taedzwa.
Iyo microhardness tester ine zvinodiwa zvekupedza pamusoro peiyo yakaedzwa sampu, iyo inoda kunyatsogadzirirwa zvinoenderana nemetallographic sample.
Iyo microhardness test musimboti muiyo microhardness test nzira yakangofanana nekuoma kweVickers, asi mutoro unoshandiswa idiki pane yakaderera-mutoro Vickers kuomarara, kazhinji isingasviki 1000g, uye inokonzeresa indentation ingori mashoma mamicrons kune mashoma maviri. microns, saka iyo microhardness bvunzo inopa yakanakira nzira yekudzidza iyo microstructure zvimiro zvepermeable layer.Inoshandiswa zvakanyanya kuona kuoma kwechikamu chimwe nechimwe pamusoro uye muchikamu chinopinda.
Chiratidzo che microhardness chinowanzo ratidzwa neHV, uye iyo yekutsunga musimboti uye nzira yakafanana neiyo Vickers kuoma nzira.Iyo yekurodha sisitimu, yekuyera sisitimu uye indenter chaiyo ye microhardness tester iri kudiwa kupfuura iyo yakaderera-mutoro Vickers kuomarara tester.Parizvino, microhardness tester inoshandiswa zvakanyanya mumatete workpieces, uye nekuti magnification anogona kusvika mazana mana nguva, inowanzoshandiswa seyakapusa metallographic maikorosikopu.
Mukuita kwekushandisa, kutarisisa kunofanirwa kubhadharwa kune mutoro, micrometer uye indenter yeiyo microhardness tester, iyo inofanirwa kuongororwa isati yashandiswa, uye iyo yakaoma block inoshandiswa pakuzivikanwa kwakazara kweiyo inoratidza kukosha kwayo.
Iyo microhardness tester inoshandisa iyo mutoro muyedzo mashandiro seyakatsetseka uye yunifomu sezvinobvira, pasina kukanganisa uye vibration.Kuti uve nechokwadi chechokwadi chemhedzisiro yebvunzo, zvinowanzodikanwa kuyera kakati wandei muzvikamu zvakasiyana, uye kuwana avhareji kukosha kumiririra kukosha kwekuoma kweiyo permeability test layer kana alloy phase.Kune iyo infiltration layer inoshandiswa pakupisa kwepamusoro, kuomarara kwayo kunogona kuyerwa nekushandisa tembiricha yepamusoro microhardness tester.
